G3412C, G3508, G3512 and G3516 Engines Status Control Module Caterpillar


Engine Shutdown Unexpected and All Fault Indicators Are Flashing

Usage:

G3516 4EK
System Operation Description:

Use this procedure if an engine shutdown occurs and all six fault indicators are flashing. Also use this procedure if all six of the fault indicators are flashing.

Test Step 1. Inspect Electrical Connectors and Wiring

  1. Turn the main disconnect switch to the OFF position.

  1. Thoroughly inspect all of the connectors that are associated with the circuit.

Expected Result:

All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion and of pinch points.

Results:

  • OK - The harness and connectors appear to be OK. Proceed to Test Step 2.

  • Not OK - There is a problem with the connectors and/or wiring.

    Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.

    STOP

Test Step 2. Check the Voltage at the Status Control Module (SCM)

  1. Disconnect the wire from terminal 8 at the SCM.

  1. Turn the main disconnect switch to the ON position.

  1. Measure the voltage between the +Battery terminal and the −Battery terminal at the SCM.

Expected Result:

The fault indicators remain flashing. The voltage is 15 VDC or higher.

Results:

  • OK - The fault indicators remain flashing. The voltage is 15 VDC or higher.

    Repair: Replace the SCM.Verify that the repair eliminates the problem.

    STOP

  • Not OK - The fault indicators remain flashing. The voltage is 15 VDC or less.

    Repair: Charge the battery or replace the battery. Verify the wiring harness is OK.Verify that the repair eliminates the problem.

    STOP

  • Not OK - The fault indicators are not flashing.

    Repair: Check the wiring and/or connectors between the SCM and the battery.Verify that the repair eliminates the problem.

    STOP
