Unit Location Fuse No. Capacity Front fog lamp IPDM E/R #58 15 A Is the fuse fusing?
YES: GO TO 2.
NO: GO TO 3.
- CHECK FRONT FOG LAMP SHORT CIRCUIT
- Disconnect IPDM E/R connector and the front combination lamp connector.
- Check continuity between the IPDM E/R harness connector and the ground.CONTINUITY REFERENCE CHART
IPDM E/R Ground Continuity Connector Terminal RH E8 86 Not existed LH 87 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.)
- CHECK FRONT FOG LAMP BULB

Is the bulb normal?
YES: GO TO 4.
NO: Replace the bulb.
- CHECK FRONT FOG LAMP OUTPUT VOLTAGE
CONSULT-III ACTIVE TEST
- 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
