Diagnosis Procedure

1. Turn the ignition switch OFF.
2. Check that the following fuse is not fusing.

   Unit	Location	Fuse No.	Capacity
   Front fog lamp	IPDM E/R	#65	15 A

   Is the fuse fusing? 

   YES: GO TO 2.

   NO: GO TO  3.

1. Disconnect IPDM E/R connector and the front fog connector.
2. Check continuity between the IPDM E/R harness connector and the ground.

   IPDM E/R			Ground	Continuity
   Connector		Terminal
   RH	E12	17		Not existed
   LH		16

   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 the applicable lamp bulb.

Is the bulb normal? 

YES: GO TO 4.

NO: Replace the bulb.

CONSULT ACTIVE TEST

1. Disconnect the front fog lamp connector.
2. Turn the ignition switch ON.
3. Select "EXTERNAL LAMPS" of IPDM E/R active test item.
4. With operating the test items, check the voltage between the IPDM E/R harness connector and the ground.

   Terminals				Test item	Voltage (Approx.)
   (+)			(-)
   IPDM E/R			Ground	EXTERNAL LAMPS
   Connector		Terminal
   RH	E12	17		Fog	Battery voltage
   LH		16		Off	0 V

   Is the measurement value normal? 

   YES: GO TO 5.

   NO: Replace IPDM E/R.

1. Turn the ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check continuity between the IPDM E/R harness connector and the front fog lamp harness connector.

   IPDM E/R			Front fog lamp		Continuity
   Connector		Terminal	Connector	Terminal
   RH	E12	17	E48	2	Existed
   LH		16	E30	2

   Does continuity exist? 

   YES: GO TO 6.

   NO: Repair the harnesses or connectors.

Check continuity between the front fog lamp harness connector and the ground.

Does continuity exist? 

YES: Replace the front fog lamp.

NO: Repair the harnesses or connectors.
