Dash Lights Brightness Controller

Controller Input Test

NOTE: The control unit is built into the dash lights brightness controller.

1. Carefully pry the controller out of the dashboard, then disconnect the 3P connector from the controller.

2. Inspect the connector 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, make the following 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 controller must be faulty; replace it.
