Diagnosis Procedure

1.CHECK DAYTIME RUNNING LIGHT RELAY FUSE
Check that the following fuse is not fusing.





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





Is the measurement value normal?
YES - GO TO 3.
NO - Repair harnesses or connectors.
3.CHECK DAYTIME RUNNING LIGHT RELAY
Check the daytime running light relay. Component Inspection.
Is the daytime running light relay normal?
YES - GO TO 4.
NO - Replace the daytime running light relay.
4.CHECK DAYTIME RUNNING LIGHT RELAY CONTROL SIGNAL OUTPUT
CONSULT-III ACTIVE TEST
1. Turn the ignition switch OFF.
2. Install the daytime running light relay.
3. Turn the ignition switch ON.
4. Select "EXTERNAL LAMPS" of IPDM E/R active test item.
5. With operating the test item, check voltage between the IPDM E/R harness connector and the ground.





Is the measurement value normal?
YES - Check the parking lamp circuit. Diagnosis Procedure.
Fixed at 0 V - GO TO 5.
Fixed at battery voltage -Replace IPDM E/R.
5.CHECK DAYTIME RUNNING LIGHT RELAY CONTROL SIGNAL OPEN CIRCUIT
