When reporting the repair, use "PS4646" as the Part number and "7755" as the Group Number. If administered before failure, use "56" as the Warranty Claim Description Code and use "T" as the SIMS Description Code. If administered after failure, use "96" as the Warranty Claim Description Code and use "Z" as the SIMS Description Code.

NOTE: Although this Program is to be administered as described above on the Affected Product, parts should be removed from parts stock as soon as possible.

NOTE: This Revised Service Letter replaces the May 15, 2000 (Revised June 2000) Service Letter. Changes have been made to the Termination Date, Parts Needed (Flash Files), and the Rework Procedure. Tractors previously reworked do NOT need to be further updated.

TERMINATION DATE

May 31, 2002

PROBLEM

The software in the tractor engine Electronic Control Module (ECM) supporting the Caterpillar Information Display (Cat ID) feature in some early tractors contains errors. The key errors relate to the calculation of fuel consumption and PM intervals. New software has been developed to address these errors. Besides flashing this updated software to the ECM in each of the affected tractors, a new EPROM chip will need to be installed in the Cat ID electronic display module in those tractors so equipped. A later group of tractors needs only the new ECM software flashed. In addition to resolving the problem issues mentioned above, the new EPROM chip and ECM software will also correct the Pin H problem when using the Electronic Technician (ET) with the Universal Data Link Cable detailed in a previous service publication. The capability of the ECM and Cat ID display to support the engine idle shutdown timer has been removed. NOTE: Intermittent screen blanking and occasional complete shutdown of the Cat ID have been recently encountered in applications of the Cat ID in the on-highway trucking market. This Service Letter is primarily software focused, and will not necessarily address that problem. Refer to "Mechanical Failures of Cat ID", Technical Information Bulletin, February 9, 2000.

PARTS DISPOSITION

Handle the parts in accordance with your Warranty Bulletin on warranty parts handling.

Attach. (1-Rework Procedure)

Rework Procedure

Group 1: 1) Using an Electronic Service Tool, ET (Electronic Technician - JERD2124 Version 3.0 [Oct99] or higher), flash the engine ECM with the updated software appropriate to the tractor model. (A 7X-1700 Communications Adapter and proper connecting cables are required.) Additional information can be found in the article "Recommended Service Tooling", on p. 3 of the November 17, 1997, issue of the Service Magazine, and the Service Manual module, "Troubleshooting 3176C and 3196 Engines For Caterpillar Built Machines (For Use In Challenger 65E, 75E, 85E And 95E Ag Tractors)", Form No: RENR1383.

NOTE: Because of errors with the original ECM software, all tractor parameter values related to fuel consumption may not be accurate. Complete the following steps to eliminate or minimize the errors. 2) Obtain factory passwords to allow reprogramming of the ECM lifetime fuel consumption value. (You will need to provide the following: Service Tool S/N, Engine S/N, ECM S/N, Total Tattletale Count, and Reason Code.)

Reference: Troubleshooting (3176C and 3196 Engines for use in Challenger 65E, 75E, 85E and 95E Ag Tractors) Service Manual Module; Form No. RENR1383.

3) Determine if the ECM "Fuel Rate Scaling" factor has been programmed by checking the fuel rate scaling factor tattletale on the configuration screen. (Any tattletale number other than "0" indicates the factor has been programmed.)

4) If the "Fuel Rate Scaling" factor has not been programmed, double check to make sure it is currently set at "0". Go to the Information/Current Totals screen. Then reset the "Total Fuel" value to 0.50 (50%) of the existing number. (For example, if the current "Total Fuel" reading is 1000, reset it to 500.) In like manner, reset the "Total Max Fuel" to 0.50 (50%) of the existing number. These resets will require the previously obtained factory passwords. (In this case, all future software output parameters, including all "Lifetime Totals", will be accurate.)

If the "Fuel Rate Scaling" factor has been programmed, reset it to "0". Then reset the "Total Fuel" consumed value to 0.67 (67%) of the existing number. (For example, if the current "Total Fuel" reading is 1000, reset it to 670.) In like manner, reset the "Total Max Fuel" to 0.67 (67%) of the existing number. This will require the previously obtained factory passwords. (In this case, all future software output parameters, except "Lifetime Totals" related to fuel consumption, will be accurate. The "Lifetime Totals" related to fuel consumption will NOT be accurate. However, lifetime accuracy will improve as more fuel is consumed by the tractor engine.)

2) If the tractor cab is not equipped with a radio, remove the 9U-8263 Cover installed in the right hand opening in the cab headliner bezel. (Refer to Illustration 1.)

3) If the tractor cab is equipped with either the AM/FM Stereo Radio with weatherband and cassette or AM/FM Stereo Radio with cassette and CD changer controls, remove the radio from the headliner bezel support using the proper removal aid (provided with each radio). Disconnect the electrical harness connector, antenna connector, and the CD changer electrical connector (if so equipped). (Refer to Illustration 1.)

4) Open the access door located at the left hand side of the cab headliner bezel.

5) If the tractor cab is equipped with a CD Changer Group behind the access door, remove the four (4) 136-5634 Screws at the bottom surface of the headliner which retain the CD changer support bracket. Retain. Carefully slide the CD changer forward into the headliner opening. Once the changer is slid past the bezel and bezel support, rotate the changer away from the right hand edge of the access opening. (Refer to Illustration 2.)

6) Reach in through the now exposed bezel openings to unscrew the two (2) knurled screws retaining the electronic display support bracket. Remove the bracket. Slide the 145-0145 Electronic Display Gp. rearward out of the bezel opening. Disconnect the electrical harness connector. (Refer to Illustration 3.)

7) Grasp both sides of the EPROM cover at the tabs and remove it from the back of the display. Do not use a screwdriver to remove the EPROM cover. Damage to the display will result. (Refer to Illustration 4.)

8) Remove the existing 145-0141 EPROM/Carrier from the display by carefully grasping the tabs at the top and bottom and removing the carrier. Do not use a screwdriver to remove the EPROM/Carrier. Damage to the display will result. Discard. (Refer to Illustration 5.)

9) Install the new 171-2087 EPROM/Carrier. Match the notches at the top and bottom of the EPROM carrier cavity with the EPROM carrier. Insert the EPROM until the top of the carrier is flush with the carrier cavity.

10) Reinstall the removed EPROM cover.

11) Reconnect the electronic display electrical connector to the wiring harness. Slide the display back into the headliner bezel opening. Position the display and retain with the previously removed support bracket and retaining screws.

12) Reposition the CD Changer Group (with support bracket) within the headliner opening, if previously moved in Step 5. Retain with the four (4) removed 136-5634 Screws.

13) Reconnect the radio electrical harness connector, antenna connector, and CD changer electrical connector (if so equipped), if previously disconnected in Step 3. Slide the radio into position in the headliner bezel opening until it snaps in place.

14) If the tractor cab is not equipped with a radio, reinstall the previously removed 9U-8263 Cover in the right hand opening in the cab headliner bezel.

15) Check for proper radio and electronic display operation.

Complete the following steps to reflash the engine ECM software and reprogram selected Cat ID parameters. 16) Using an Electronic Service Tool, ET (Electronic Technician - JERD2124 Version 3.0 [Oct99] or higher), flash the engine ECM with the updated software appropriate to the tractor model. (A 7X-1700 Communications Adapter and proper connecting cables are required.) Additional information can be found in the article "Recommended Service Tooling", on p. 3 of the November 17, 1997, issue of the Service Magazine, and the Service Manual module, "Troubleshooting 3176C and 3196 Engines For Caterpillar Built Machines (For Use In Challenger 65E, 75E, 85E And 95E Ag Tractors)", Form No: RENR1383.
NOTE: While new ECM software is flashed, the Cat ID screen will display "Application Not Recognized." This is normal.

NOTE: Because of errors with the original ECM software, all tractor parameter values related to fuel consumption may not be accurate. Complete the following steps to eliminate or minimize the errors.

17) Note any desired, existing (non-Lifetime Totals) electronic display data; recognizing fuel value accuracy is questionable. (This data will be erased during the next steps.) Complete Steps 18 and 19 using the appropriate electronic display unit input keys. (Refer to the Special Instruction, "Caterpillar Information Display", Form No: REHS0193.) 18) Reset the "Rolling Totals" values.

19) Reset the "Current Field Totals" values TWICE. This will "zero out" the total values for the "Current Field Totals" and the "Last Field Totals."

NOTE: If you are unable to reset "Rolling Totals" and "Field Totals" at the Cat ID screen, the corresponding software parameters need to be reset. Using the ET Service Tool go to the Configuration/ Service screen. Then change the "Rolling Totals Manual Reset Status" from "Enable" to "Disable." Repeat the step with the "Field Totals Manual Reset Status." Complete Steps 20, 21, and 22 using the Electronic Technician.

Obtain factory passwords to allow reprogramming of the ECM lifetime fuel consumption value. (You will need to provide the following: Service Tool S/N, Engine S/N, ECM S/N, Total Tattletale Count, and Reason Code.)

Reference: Troubleshooting (3176C and 3196 Engines for use in Challenger 65E, 75E, 85E and 95E Ag Tractors) Service Manual Module; Form No. RENR1383. 21) Determine if the ECM "Fuel Rate Scaling" factor has been programmed by checking the fuel rate scaling factor tattletale on the configuration screen. (Any tattletale number other than "0" indicates the factor has been programmed.)

22) If the "Fuel Rate Scaling" factor has not been programmed, double check to make sure it is currently set at "0". Go to the Information/Current Totals screen. Then reset the "Total Fuel" value to 0.50 (50%) of the existing number. (For example, if the current "Total Fuel" reading is 1000, reset it to 500.) In like manner, reset the "Total Max Fuel" to 0.50 (50%) of the existing number. These resets will require the previously obtained factory passwords. (In this case, all future software output parameters, including all "Lifetime Totals", will be accurate.)

Group 3:

Complete the following steps to replace the Cat ID electronic display EPROM/Carrier chip.

1) Make sure that the Engine Start Switch is in the OFF position.

2) If the tractor cab is not equipped with a radio, remove the 9U-8263 Cover installed in the right hand opening in the cab headliner bezel. (Refer to Illustration 1.)

4) Open the access door located at the left hand side of the cab headliner bezel.

6) Reach in through the now exposed bezel openings to unscrew the two (2) knurled screws retaining the electronic display support bracket. Remove the bracket. Slide the 164-5766 Electronic Display Gp. rearward out of the bezel opening. Disconnect the electrical harness connector. (Refer to Illustration 3.)

8) Remove the existing 164-5764 EPROM/Carrier from the display by carefully grasping the tabs at the top and bottom and removing the carrier. Do not use a screwdriver to remove the EPROM/Carrier. Damage to the display will result. Discard. (Refer to Illustration 5.)

Group 4: 1) Using an Electronic Service Tool, ET (Electronic Technician - JERD2124 Version 3.0 [Oct99] or higher), flash the engine ECM with the updated software appropriate to the tractor model. (A 7X-1700 Communications Adapter and proper connecting cables are required.) Additional information can be found in the article "Recommended Service Tooling", on p. 3 of the November 17, 1997, issue of the Service Magazine, and the Service Manual module, "Troubleshooting 3176C and 3196 Engines For Caterpillar Built Machines (For Use In Challenger 65E, 75E, 85E And 95E Ag Tractors)", Form No: RENR1383.

NOTE: Because of errors with the original ECM software, all tractor parameter values related to fuel consumption may not be accurate. Complete the following steps to eliminate or minimize the errors.

Obtain factory passwords to allow reprogramming of the ECM lifetime fuel consumption value. (You will need to provide the following: Service Tool S/N, Engine S/N, ECM S/N, Total Tattletale Count, and Reason Code.)

Reference: Troubleshooting (3176C and 3196 Engines for use in Challenger 65E, 75E, 85E and 95E Ag Tractors) Service Manual Module; Form No. RENR1383. 3) Determine if the ECM "Fuel Rate Scaling" factor has been programmed by checking the fuel rate scaling factor tattletale on the configuration screen. (Any tattletale number other than "0" indicates the factor has been programmed.)

NOTE: If a Cat ID electronic display module is installed in the tractor cab at a later time, the "Rolling Totals", "Current Field Totals", and "Last Field Totals" information from the ECM will need to be reset at that time using the display input keys. (Refer to the Special Instruction, "Caterpillar Information Display", Form No: REHS0193.) Group 5: 1) Using an Electronic Service Tool, ET (Electronic Technician - JERD2124 Version 3.0 [Oct99] or higher), flash the engine ECM with the updated software appropriate to the tractor model. (A 7X-1700 Communications Adapter and proper connecting cables are required.) Additional information can be found in the article "Recommended Service Tooling", on p. 3 of the November 17, 1997, issue of the Service Magazine, and the Service Manual module, "Troubleshooting 3176C and 3196 Engines For Caterpillar Built Machines (For Use In Challenger 65E, 75E, 85E And 95E Ag Tractors)", Form No: RENR1383.
NOTE: While new ECM software is flashed, the Cat ID screen will display "Application Not Recognized." This is normal.

NOTE: Because of errors with the original ECM software, all tractor parameter values related to fuel consumption may not be accurate. Complete the following steps to eliminate or minimize the errors.

2) Note any desired, existing (non-Lifetime Totals) electronic display data; recognizing fuel value accuracy is questionable. (This data will be erased during the next steps.) Complete Steps 3 and 4 using the appropriate electronic display unit input keys. (Refer to the Special Instruction, "Caterpillar Information Display", Form No: REHS0193.) 3) Reset the "Rolling Totals" values.

4) Reset the "Current Field Totals" values TWICE. This will "zero out" the total values for the "Current Field Totals" and the "Last Field Totals."

Obtain factory passwords to allow reprogramming of the ECM lifetime fuel consumption value. (You will need to provide the following: Service Tool S/N, Engine S/N, ECM S/N, Total Tattletale Count, and Reason Code.)

Reference: Troubleshooting (3176C and 3196 Engines for use in Challenger 65E, 75E, 85E and 95E Ag Tractors) Service Manual Module; Form No. RENR1383. 6) Determine if the ECM "Fuel Rate Scaling" factor has been programmed by checking the fuel rate scaling factor tattletale on the configuration screen. (Any tattletale number other than "0" indicates the factor has been programmed.)

7) If the "Fuel Rate Scaling" factor has not been programmed, double check to make sure it is currently set at "0". Go to the Information/Current Totals screen. Then reset the "Total Fuel" value to 0.50 (50%) of the existing number. (For example, if the current "Total Fuel" reading is 1000, reset it to 500.) In like manner, reset the "Total Max Fuel" to 0.50 (50%) of the existing number. These resets will require the previously obtained factory passwords. (In this case, all future software output parameters, including all "Lifetime Totals", will be accurate.)
