Daytime Running Lamp Control Unit: Testing and Inspection

Daytime Running Lights Control Unit Input Test (Canada)

1. Remove the driver's dashboard lower cover.




2. Disconnect the 1 4P connector (A) from the daytime running lights control unit (B).
3. Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 4.




4. Make these input tests at the connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the control unit must be faulty; replace it.
