PINPOINT TEST 10: DTC B2A25 - TRIM PANEL LOCK SWITCH CIRCUIT FAILURE - HYBRID
Normal Operation
The smart junction box (SJB) sends voltage signals to the door lock control switches through circuits (L/G) and (Y/V) for the lock and unlock requests. When the lock or unlock switch is pressed, the voltage signal is routed to ground. Ground for both door lock control switches is provided through circuit (B/GY).
- DTC B2A25 (Trim Panel Lock Switch Circuit Failure) - an on-demand DTC that sets when the SJB detects a short to ground from the lock or unlock request input circuits. This DTC may also set if either of the door lock control switches are pressed for longer than 2 minutes.
Possible Causes
- Wiring, terminals or connectors
- Door lock control switch
- SJB
Diagnostic Procedure
CAUTION:Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
