Pinpoint Test 1: All Door Locks Are Inoperative From One Switch
PINPOINT TEST 1: ALL DOOR LOCKS ARE INOPERATIVE FROM ONE SWITCHNormal Operation
The smart junction box (SJB) monitors circuits (GY/Y) and (V/GY) for a ground signal. If the door lock control switch connects circuit (GY/Y) to ground circuit (B/Y) or circuit (B/L) the doors lock. If the door lock control switch connects circuit (V/GY) to the ground circuit (B/Y) or circuit (B/L) the doors unlock.
DTC B1309 - (Power Door Lock Circuit Short To Ground) - is an on demand DTC that sets when the SJB senses a short to ground on circuit (GY/Y).
DTC B1341 - (Power Door Unlock Circuit Short To Ground) - is an on demand DTC that sets when the SJB senses a short to ground on circuit (V/GY).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door lock control switch(es)
- Passenger door lock control switch
- SJB
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
