Diagnosis Procedure

CONSULT ACTIVE TEST

1. Turn the ignition switch OFF.
2. Disconnect the headlamp low connector.
3. Turn the ignition switch ON.
4. Select "EXTERNAL LAMPS" of IPDM E/R active test item.
5. 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	20		Lo	Battery voltage
   LH		18		Off	0 V

   Is the measurement value normal? 

   YES: GO TO 2.

   NO: GO TO  3.

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

   IPDM E/R			Headlamp low		Continuity
   Connector		Terminal	Connector	Terminal
   RH	E12	20	E74	1	Existed
   LH		18	E71	1

   Does continuity exist? 

   YES: GO TO  5.

   NO: Repair the harnesses or connectors.

1. Turn the ignition switch OFF.
2. Check that the following fuses are not fusing.

   Unit	Lotion	Fuse No.	Capacity
   Headlamp LO (LH)	IPDM E/R	#49	15 A
   Headlamp LO (RH)	IPDM E/R	#50	15 A

   Is the fuse fusing? 

   YES: GO TO 4.

   NO: Replace IPDM E/R.

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

   IPDM E/R			Ground	Continuity
   Connector		Terminal
   RH	E12	20		Not existed
   LH		18

   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.)

1. Turn the ignition switch OFF.
2. Disconnect the headlamp low connector.
3. Check continuity between the headlamp low harness connector and the ground.

   Headlamp low			Ground	Continuity
   Connector		Terminal
   RH	E74	2		Existed
   LH	E71	2

   Does continuity exist? 

   YES: Perform the xenon headlamp diagnosis. Refer to "DESCRIPTION ".

   NO: Repair the harnesses or connectors.
