Reference the Service Tool Communication Settings and Connections for additional information if needed.
Verify Plus+1 Service Tool for Cat (P1STC) is communicating with the machine. The connection status must be "Connected" or "Logging" (1). Follow the on-screen instructions under Step 1 (See Illustration 5) if the status is "Disconnected".
P1STC requires a machine-specific "P1D" diagnostic file to service any machine. The machine model and serial number prefix are used to look up the diagnostic file. Select the "P1D Help" icon. Use the cross reference document and make a note of the specific diagnostic "P1D" file name.
Manually select Your machine-specific diagnostic file by selecting the "Open Folder" icon. Then open the Cat Diagnostic Files folder to select and open the diagnostic file.

Flash Screen (4) "ECM Service" Selection | |
When flashing any of the machine system ECMs, the recommendation is to select the "ECM Service" (4) option. The following pages provide step by step procedures for flashing an ECM with the "ECM Service" option.
The "Quick Flash" procedure can be used for the Display, and Compaction ECMs. Configuration settings will need to be selected after flashing the Display. Calibration of the angle sensor will need to be performed after flashing the Compaction ECM.
The "Quick Flash" procedure will NOT save the machine parameters or calibrations. If flashing the "Main Machine Control" ECM, a "Propel Currents Calibration" procedure must be performed if parameters are not saved. Refer to Systems Operation, Testing and Adjusting, UENR2051, "Propel Current Minimum - Calibrate".
Follow steps 6 to 8 for Quick Flash instructions after selecting "Quick Flash" and the "Flash ECM" button.

- Set the configurations if the Display was flashed. Refer to Testing and Adjusting, "Electronic Control Module (ECM) – Configure".
Calibration of the angle sensor is required if the Compaction ECM was flashed. Refer to Testing and Adjusting, "Machine Drive Power Angle Sensor - Calibrate".
This step completes a successful flash procedure. Continue to the next step if the ECM flash was unsuccessful.
Note: If the application (flash file) type does not match the application type already on the ECM, a mismatch error will be displayed. To address this issue, perform the following steps.
- Confirm that the selected flash file is the desired flash file. The selected flash file is listed in the "File Download" window. If the incorrect file was selected, click "Cancel" and repeat the process to select the correct file. If the correct file has been selected, continue to the next step. Enter the new software part number in the location provided.
- Do not include dashes.
- Do not include the revision number.
If the new software name is not accepted, review the service literature that specified the new flash file. Check if an alternate application type has been provided.
Try the "Recover a Controller (ECM)" procedure and repeat the flash procedure.
If the recovery / flash attempt fails, contact your dealership for possible consultation with Caterpillar. This consultation may greatly reduce repair time.
Recovering the ECM may be necessary if the connection was lost during a flash procedure. Recovering the ECM may also be needed if the Plus+1 Service Tool for Caterpillar (P1STC) cannot communicate with the ECM.
