Test E: DTC B2A25 Trim Panel Lock Switch Circuit Failure

PINPOINT TEST E: DTC B2A25 TRIM PANEL LOCK SWITCH CIRCUIT FAILURE

Normal Operation
The SJB sends voltage signals to the door lock control switches through circuits CPK19 (BU/GN) and CPK23 (YE/VT) for the lock and unlock requests, respectively. When the lock or unlock switch is pressed, the voltage signal is routed to ground. Ground for the LH door lock control switch is provided through circuit GD133 (BK). Ground for the RH door lock control switch is provided through circuit GD148 (BK/YE).

DTC B2A25 (Trim Panel Lock Switch Circuit Failure) - is 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.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door lock control switch
- SJB
