Dashlights Brightness Controller Test/Replacement

Dashlights Brightness Controller Test/Replacement

1. Remove the instrument fascia Instrument Fascia Removal / Installation.

2. Disconnect the 6P connector (A) from the dashlights brightness controller (B).





3. Remove the two screws and the dashlights brightness controller.

4. Check for continuity between the terminals in each switch position according to the table.

NOTE:

- Make sure the correct test lead (+ or -) is placed on the terminal.
- When checking for continuity across the diode, use the diode setting () on the digital volt/ohm meter to check the diode bias.
- Be careful of this characteristic; a diode is one that conducts fully in one direction (forward) and not at all in the opposite direction (reverse).





5. If the continuity is not as specified or LEDs do not turn on, replace the controller.

6. Install the parts in the reverse order of removal.
