TROUBLESHOOTING USING GSC FAULT CODES - Continued
CID 170 E FMI 01
Fuel filter change required.
FMI 01 - Data is Valid but Data is Below Normal Operating Range.
Event Code. Inspect fuel filter for leaks, proper mounting, cracks, damage, or missing parts and
change fuel filter.
Set Battery Disconnect Switch to ON; Set DEAD CRANK SWITCH to NORMAL.
On EMCP, turn ENGINE CONTROL switch to COOL DOWN/ STOP.
Reset CATSW1 after fuel filter change.
Record fuel filter maintenance.
Verify the fault code has cleared.
The following codes are generated when the air manifold temperature sensor sees a
temperature greater than 194 F (90 C) for two seconds or longer (FMI 00); or greater than
228 F (109 C) (FMI 11) for two seconds or longer. This problem is often caused by one of the
Incorrect fuel injection timing
Low air inlet system pressure
Restriction in air inlet
