Daytime Running Light Relay Circuit

DAYTIME RUNNING LIGHT RELAY CIRCUIT





Component Function Check
1.CHECK DAYTIME RUNNING LIGHT OPERATION
CONSULT-III ACTIVE TEST
1. Select "DAYTIME RUNNING LIGHT" of BCM (HEADLAMP) active test item.
2. With operating the test items, check that daytime running light operation.





Is the inspection result normal?
YES - Daytime running light relay circuit is normal.
NO - SEE Diagnosis Procedure.




Diagnosis Procedure
1.CHECK DAYTIME RUNNING LIGHT RELAY 2 FUSE
1. Turn ignition switch OFF.
2. Check that the following fuse is not fusing.





Is the inspection result normal?
YES - GO TO 2.
NO - Replace the fuse after repairing the applicable circuit.
2.CHECK DAYTIME RUNNING LIGHT RELAY 2 POWER SUPPLY
1. Remove daytime running light relay.
2. Check voltage between daytime running light relay 2 harness connector and ground.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace harness.
3.CHECK DAYTIME RUNNING LIGHT RELAY 2
Check daytime running light relay 2. SEE Component Inspection.
Is the inspection result normal?
YES - GO TO 4.
NO - Replace daytime running light relay 2.
4.CHECK DAYTIME RUNNING LIGHT RELAY 2 CONTROL SIGNAL OUTPUT
CONSULT-III ACTIVE TEST
1. Install daytime running light relay 2.
2. Turn ignition switch ON.
3. Select "DAYTIME RUNNING LIGHT" of BCM (HEADLAMP) active test item.
4. With operating the test item, check voltage between IPDM E/R harness connector and ground.





Is the inspection result normal?
YES - Daytime running light relay 2 circuit is OK.
NO-1 (Fixed at 0 V)-GO TO 5.
NO-2 (Fixed at battery voltage) -Replace IPDM E/R.
5.CHECK DAYTIME RUNNING LIGHT RELAY 2 CONTROL SIGNAL OPEN CIRCUIT
1. Turn ignition switch OFF.
2. Remove daytime running light relay 2.
3. Disconnect IPDM E/R harness connector.
4. Check continuity between IPDM E/R harness connector and daytime running light relay 2 harness connector.





Is the inspection result normal?
YES - GO TO 6.
NO - Repair or replace harness.
6.CHECK DAYTIME RUNNING LIGHT RELAY 2 CONTROL SIGNAL SHORT CIRCUIT
Check continuity between IPDM E/R harness connector and ground.





Is the inspection result normal?
YES - Replace IPDM E/R.
NO - Repair or replace harness.




Component Inspection
