BRN Wire Communication Line Test
BRN Wire Communication Line Test
1. Remove the driver's multiplex control unit from the driver's under-dash fuse/relay box.
2. Carefully pry off the driver's door switch trim.
3. Disconnect door multiplex control unit connector A (20P).
4. Check for continuity between the A2 terminal of the driver's under-dash fuse/relay box socket and the No.15 terminal of door multiplex control
unit connector A (20P).
Is there continuity?
YES - Replace the multiplex control unit most closely related to the failure.
NO - Repair an open in the wire between the door multiplex control unit connector and the driver's under-dash fuse/relay box. If the wire is OK,
replace the driver's under-dash fuse/relay box.
Gauge Control Module Input Test
Gauge Control Module Input Test
NOTE: If there is malfunction of the parking brake reminder and speedometer function simultaneously, troubleshooting the vehicle speed signal circuit
first.
1. Remove the gauge control module and disconnect 36P connector B from the gauge control module.
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. Reconnect the connectors to the gauge control module, and 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 gauge internal circuit must be faulty; replace the gauge control module.
