Dimmer Switch: Testing and Inspection
Control Unit Input Test
Control Unit Input Test
Driver's Multiplex Control Unit
1. Remove the driver's multiplex control unit from the driver's under-dash fuse/relay box.
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. With the driver's multiplex control unit still disconnected, make these input tests at the connector and driver's under-dash fuse/relay box socket.
-
If any test indicates a problem, find and correct the cause, then recheck the system.
-
If all the input tests prove OK, go to step 4.
