TROUBLESHOOTING USING GSC FAULT CODES - Continued
NOTE
The following failure is usually a broken wire, or a frayed wire shorting to an adjacent wire or to
ground.
SYMPTOM
17.
CID 100 E FMI 03
CID 100 E FMI 04
MALFUNCTION
Oil pressure sensor.
FMI 03 - Voltage Above Normal.
FMI 04 - Voltage Below Normal.
CORRECTIVE ACTION
Troubleshoot oil pressure sensor using steps in SYMPTOM 13.
NOTE
This failure indicates that GSC is unable to receive any valid data about the coolant temperature
from the ECM.
SYMPTOM
18.
CID 110 E FMI 02
CID 110 E FMI 03
CID 110 E FMI 04
MALFUNCTION
Engine coolant temperature sensor.
FMI 02 - Erratic, Intermittent, or Incorrect Signal.
FMI 03 - Voltage Above Normal.
FMI 04 - Voltage Below Normal.
CORRECTIVE ACTION
STEP 1.
On EMCP, turn ENGINE CONTROL switch to OFF/RESET. Battery Disconnect
Switch is OFF; DEAD CRANK SWITCH is OFF.
STEP 2.
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).
STEP 3.
Conduct an appropriate pull test on wires in the ENG-P2 and ENG-P1
connectors to ensure wires are tight and secure.
STEP 4.
Check the wires on both harnesses for abrasion and pinch points (WP 0090).
Repair and/or replace the connectors and/or wiring (WP 0090).
STEP 5.
Disconnect engine harness connector ENG-P6 from engine coolant temperature
sensor (WP 0090, Figure 1, sheet 1, and FO-2, sheet 1).
