1.CHECK HEADLAMP (LO) OUTPUT VOLTAGE CONSULT-III ACTIVE TEST

1. Turn the ignition switch OFF.
2. Disconnect the front combination lamp 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 | E8 | 83 | Lo | Battery voltage
   Off | 0 V
   LH | 84 | Lo | Battery voltage
   Off | 0 V

Is the measurement value normal?
YES>>GO TO 2.
NO>>GO TO 3.
2.CHECK HEADLAMP (LO) OPEN CIRCUIT

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 combination lamp harness connector.

   IPDM E/R | Front combination lamp | Continuity
   Connector | Terminal | Connector | Terminal
   RH | E8 | 83 | E58 | 5 | Existed
   LH | 84 | E28 | 5

Does continuity exist?
YES>>GO TO 5.
NO>>Repair the harnesses or connectors.
3.CHECK HEADLAMP (LO) FUSE

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

   Unit | Lotion | Fuse No. | Capacity
   Headlamp LO (RH) | IPDM E/R | #57 | 15 A
   Headlamp LO (LH) | IPDM E/R | #56 | 15 A

Is the fuse fusing?
YES>>GO TO 4.
NO>>Replace IPDM E/R.
4.CHECK HEADLAMP (LO) SHORT CIRCUIT

1. Disconnect the 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 | E8 | 83 | Not existed
   LH | 84

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.)
5.CHECK HEADLAMP (LO) GROUND OPEN CIRCUIT
Check continuity between the front combination lamp harness connector and the ground.

Front combination lamp | Ground | Continuity
Connector | Terminal
RH | E58 | 1 | Existed
LH | E28 | 1

Does continuity exist?
YES>>Perform the xenon headlamp diagnosis. Refer to Description.
NO>>Repair the harnesses or connectors.
