Measure and record voltage between A6B21 and A6F1 and between A6B21 and
Measure voltage at Load output terminal board, TB2, between terminals L0 and
L1 and between L0 and L3. Record voltages.
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 0090).
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 =
b. If voltage is correct, check continuity between A6P1-A and P7-17 and
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). If
Verify the problem is resolved.
CID 1589 E FMI 02
Turbocharger air inlet pressure sensor.
FMI 02 - Erratic, Intermittent, or Incorrect Signal.
On EMCP, turn ENGINE CONTROL switch to OFF/RESET. Battery Disconnect
Switch is OFF; DEAD CRANK SWITCH is OFF.
Inspect wiring and verify continuity between engine harness ENG-P2 and turbo
air inlet pressure sensor connector ENG-P11 per FO-2, sheet 1. Repair or
replace engine harness wiring (WP 0090) as necessary.
Set Battery Disconnect Switch to ON, Set DEAD CRANK SWITCH to NORMAL.
Turn ENGINE CONTROL switch to COOL DOWN/STOP.
Check for an active 02 diagnostic code. If the fault has not been resolved,
replace turbo air inlet pressure sensor (WP 0100).
If replacing sensor does not resolve fault, replace ECM (WP 0084).
Verify the problem has been resolved.
