TROUBLESHOOTING USING GSC FAULT CODES - Continued
CORRECTIVE ACTION - Continued
STEP 7.
Measure voltage at Load output terminal board, TB2, between terminals L0 (N)
and L1 and between L0 (N) and L3. Record voltages.
STEP 8.
If voltage is not same as generator output, repair or replace harness between
BTB A6 and generator output per FO-4 sheet 3 and FO-3 sheet 2 (WP 0088).
STEP 9.
Measure voltage between A6J1-A and A6J1-B per FO-4 sheet 5. Value should
be the same as the value in step 4 divided by 15: (208 Vac = 14 Vac) (416 Vac =
28 Vac).
a. If voltage is zero, or resistance measured in STEP 2 was incorrect, replace
A6 (WP 0042)
b. If voltage is correct, check continuity between A6P1-A and P7-17 and
between A6P1-B to P7-18 (WP 0042).
c.
If continuity is not present, repair or replace wiring harness as necessary
d. If problem is not resolved, check all GSC fuses (FO-4, Sheets 3 and 5).
e. If GSC fuses are ok, replace GSC (WP 0041).
STEP 10.
Verify the problem is resolved.
SYMPTOM
64.
CID 1589 E FMI 02
MALFUNCTION
Turbo Air Inlet Pressure Sensor.
FMI 02 - Erratic, Intermittent, or Incorrect Signal.
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 wiring and verify continuity between engine harness ENG-P2 and turbo
air inlet pressure sensor connector ENG-P15 per FO-2, sheet 1. Repair or
replace engine harness wiring (WP 0088).
STEP 3.
Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to NORMAL.
Turn the ENGINE CONTROL switch to COOL DOWN/STOP.
STEP 4.
Check for an active 02 diagnostic code. If the fault has not been resolved,
replace turbo air inlet pressure sensor (WP 0098).
STEP 5.
If replacing sensor does not resolve fault, replace ECM (WP 0082).
STEP 6.
Verify the problem has been resolved.
