Diagnosis Procedure
- CHECK HEADLAMP (HI) OUTPUT VOLTAGE
CONSULT-III ACTIVE TEST
- Turn the ignition switch OFF.
- Disconnect the front combination lamp connector.
- Turn the ignition switch ON.
- Select "EXTERNAL LAMPS" of IPDM E/R active test item.
- With operating the test items, check the voltage between the IPDM E/R harness connector and the ground.VOLTAGE REFERENCE CHART
Terminals Test item Voltage (Approx.) (+) (-) IPDM E/R Ground EXTERNAL LAMPS Connector Terminal RH E8 89 Hi Battery voltage Off 0 V LH 90 Hi Battery voltage Off 0 V Is the measurement value normal?
YES: GO TO 2.
NO: GO TO 3.
- CHECK HEADLAMP (HI) OPEN CIRCUIT
- Turn the ignition switch OFF.
- Disconnect IPDM E/R connector.
- Check continuity between the IPDM E/R harness connector and the front combination lamp harness connector.CONTINUITY REFERENCE CHART
IPDM E/R Front combination lamp Continuity Connector Terminal Connector Terminal RH E8 89 E28 7 Existed LH 90 E58 7 Does continuity exist?
YES: Replace the front combination lamp.
NO: Repair the harnesses or connectors.
- CHECK HEADLAMP (HI) FUSE
- CHECK FRONT COMBINATION LAMP (HI) SHORT CIRCUIT
- Disconnect IPDM E/R connector.
- Check continuity between the IPDM E/R harness connector terminal and the ground.CONTINUITY REFERENCE CHART
IPDM E/R Ground Continuity Connector Terminal RH E8 89 Not existed LH 90 Does continuity exist?
YES: Repair the harnesses or connectors. And then replace the fuse.
NO: Replace the fuse. (Replace IPDM E/R if the fuse is fusing again.)
