TROUBLESHOOTING USING GSC FAULT CODES - Continued
On EMCP, turn ENGINE CONTROL switch to OFF/RESET. Battery Disconnect
Switch is OFF; DEAD CRANK SWITCH is OFF.
Inspect connectors ENG-P2 on the engine harness (FO-2, sheet 1) and ENG-P1
on the ECM to EMCP Harness (FO-2, sheet 2).
Conduct an appropriate pull test on wires in the ENG-P2 and ENG-P1
connectors to ensure wires are tight and secure.
Check the wires on both harnesses for abrasion and pinch points (WP 0090).
Repair and/or replace the connectors and/or wiring (WP 0090), as necessary.
Set Battery Disconnect Switch to ON, Set DEAD CRANK SWITCH to NORMAL.
On EMCP, turn ENGINE CONTROL switch to COOL DOWN/STOP.
Check for FMI 03 and/or FMI 04 failure modes with associated fault codes CID
94 and CID 100 simultaneously or CID 164, CID 273, and CID 274
simultaneously. Perform the following steps if any of the fault codes are active.
a. If found, go to STEP 7 and troubleshoot engine wiring harness. Check for
opens or shorts in the sensors common wires.
b. If not found, proceed to STEP 8.
Troubleshoot engine wiring harness per WP 0090, Figure FO-2, Sheets 1 and 2.
a. Disconnect engine wiring harness connectors ENG-P1 and ENG-P2 and the
connectors to sensors listed in STEP 8.
b. Check continuity between ENG-P1 and ENG-P2 and all sensors identified in
If wires all have continuity, reconnect all sensor connectors, ENG-P1 and
ENG-P2. Proceed to STEP 8.
d. If continuity is not found, repair or replace wiring harness as necessary per
e. Reconnect all sensors, ENG-P1 and ENG-P2 and verify is the problem still
exists. If so, proceed to STEP 8.
