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.
