Trouble Diagnoses for SymptomsEFS001CC
4WD INDICATOR LAMP DOES NOT COME ON FOR APPROXIMATELY 1 SECOND WHEN THE
IGNITION SWITCH IS TURNED TO ON
Inspection Procedure
1.CHECK BLOWN FUSES BETWEEN IGN AND COMBINATION METER
Check that there are no blown fuses between IGN and combination meter.
OK or NG
OK >> GO TO 2.
NG >> Replace fuse and check again.
2.CHECK CONTINUITY BETWEEN COMBINATION METER AND 4WD/ABS CONTROL UNIT
1. Disconnect combination meter connector and 4WD/ABS control unit connector.
2. Check continuity between combination meter harness connector M44 terminal No.18 (Y/G) and 4WD/ABS
control unit harness C/U connector E122 terminal No.16 (Y/G).
OK or NG
OK >> GO TO 3.
NG >> Check harness between combination meter and 4WD/ABS control unit.
3.CHECK COMBINATION METER POWER CIRCUIT
1. Disconnect combination meter connector.
2. With ignition ON, check the voltage between the combination meter harness connector M44 terminal
No.46 (W/L) (LHD models) or No.59 (W/L) (RHD models) and body ground.
OK or NG
OK >> GO TO 4.
NG >> Check combination meter circuits.
4.CHECK 4WD AUTO LAMP (ON COMBINATION METER) CIRCUIT
Check continuity between combination meter terminal 46 (LHD models) or 59 (RHD models) and terminal 18.
OK or NG
OK >> Using CONSULT-II perform self-diagnosis.
NG >> Check for burned-out bulb in 4WD AUTO lamp.18 (YG) - 16 (Y/G) : Continuity should exist.
LHD models:46 (W/L), RHD models: 59 (W/L) 1(W) - Body ground:
Battery voltage
46 (LHD models) or 59 (RHD models) - 18:
Continuity should exist.
