Test E: DTC B1309, B1341, B2474, Or B2475: Door Lock Control Switch Circuit Short To Ground

PINPOINT TEST E: DTC B1309, B1341, B2474, OR B2475: DOOR LOCK CONTROL SWITCH CIRCUIT SHORT TO GROUND

Normal Operation
The SJB sends voltage signals to the door lock control switches through circuits 1296 (OG/BK) and 1316 (WH/VT) for the lock requests, and through circuits 1297 (YE/RD) and 1317 (DB/LG) for the unlock requests. The door lock control switches receive ground through circuit 1205 (BK). When the lock or unlock switch is pressed, the voltage signal is routed to ground.







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