1.CHECK HEADLAMP (HI) 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 | 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.
2.CHECK HEADLAMP (HI) OPEN CIRCUIT

1. Turn the ignition switch OFF.
2. Disconnect the 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 | 89 | E58 | 7 | Existed
   LH | 90 | E28 | 7

Does continuity exist?
YES (Without daytime running light system)>>GO TO 5.
YES (With daytime running light system)>>GO TO 6.
NO>>Repair the harnesses or connectors.
3.CHECK HEADLAMP (HI) FUSE

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

   Unit | Location | Fuse No. | Capacity
   Headlamp HI (RH) | IPDM E/R | #55 | 10 A
   Headlamp HI (LH) | IPDM E/R | #54 | 10 A

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

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

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

Front combination lamp | Ground | Continuity
Connector | Terminal
RH | E58 | 3 | Existed
LH | E28 | 3

Does continuity exist?
YES>>Replace the headlamp (HI) bulb. (Bulb socket is abnormally.)
NO>>Repair the harnesses or connectors.
6.CHECK HEADLAMP (HI) GROUND OPEN CIRCUIT (LH)
Check continuity between the front combination lamp LH harness connector and the ground.

Front combination lamp | Ground | Continuity
Connector | Terminal | Existed
LH | E28 | 3

Does continuity exist?
YES>>GO TO 7.
NO>>Repair the harnesses or connectors.
7.CHECK CONTINUITY BETWEEN HEADLAMP HIGH (RH) AND DAYTIME RUNNING LIGHT RELAY

1. Remove the daytime running light relay.
2. Check continuity between the front combination lamp RH harness connector and the daytime running light relay harness connector.

   Front combination lamp | Daytime running light relay | Continuity
   Connector | Terminal | Connector | Terminal | Existed
   RH | E58 | 3 | E84 | 3

Does continuity exist?
YES>>GO TO 8.
NO>>Repair the harness or connector.
8.CHECK THE DAYTIME RUNNING LIGHT RELAY GROUND OPEN CIRCUIT
Check continuity between the daytime running light relay harness connector and the ground.

Daytime running light relay | Ground | Continuity
Connector | Terminal | Existed
E84 | 4

Does continuity exist?
YES>>GO TO 9.
NO>>Repair the harness or connector.
9.CHECK THE DAYTIME RUNNING LIGHT RELAY
Check the daytime running light relay. Refer to Component Inspection.
Is the daytime running light relay normal?
YES>>Replace the headlamp (HI) bulb. (Bulb socket is abnormally.)
NO>>Replace the daytime running light relay.
