TROUBLESHOOTING USING GSC FAULT CODES - Continued
This procedure is used for FMI codes 03 and 04 for all pressure sensors.
CID 94 E FMI 03
CID 94 E FMI 04
Fuel pressure sensor.
FMI 03 - Voltage Above Normal.
FMI 04 - Voltage Below Normal.
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.
If necessary, disconnect the harness connectors, for the fuel pressure sensor,
engine oil pressure sensor, injection actuation sensor, turbo outlet pressure
sensor, atmospheric pressure sensor, and turbo inlet pressure sensor.
Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to NORMAL.
On EMCP turn the ENGINE CONTROL switch to COOL DOWN/STOP.
