Daytime Running Lights Subcontrol Unit Input Test

Daytime Running Lights Subcontrol Unit Input Test

USA ('06-07 models)




1. Disconnect the 14P connector (A) from the daytime running lights subcontrol unit (B).
2. 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 3.




3. 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.
