Description
The bcm sends a daytime light request to the ipdm e/r via the can communication lines. The power flows through fuse 29 located in fuse block j/b to the daytime light relay coil. When the ipdm e/r operates the daytime light relay, power is sent to the daytime lamps.
Diagnosis procedure
Regarding Wiring Diagram information, refer to EXL-38, "Wiring Diagram".
1.Check daytime light relay voltage supply
Is the inspection result normal? Yes >> go to 3.
No >> go to 2.
2.Check daytime light relay fuse
Check that the following fuses are not blown.
Is the fuse blown? Yes >> replace the blown fuse after repairing the affected circuit.
No >> repair or replace the harness or connector.
3.Check daytime light relay control circuit
Is the inspection result normal? Yes >> go to 4.
No >> repair or replace the harness or connector.
4.Check daytime light relay
Check the daytime light relay. Refer to exl-93, "component inspection".
Is the inspection result normal? YES >> GO TO 5.
NO >> Replace relay.
5.Check daytime light circuit (open or short to ground)
Is the inspection result normal? Yes >> go to 6.
No >> repair or replace the harness or connector.
6.Check daytime light ground circuit for open
Is the inspection result normal? Yes >> inspect daytime light bulb.
No >> repair or replace the harness or connector.
Component inspection
1. Check daytime light relay
Is the inspection result normal? Yes >> inspection end.
No >> replace daytime light relay.
