Test F: DTC B1300, B1310, Or B1982: Door Lock Actuator Relay Circuit Failure

PINPOINT TEST F: DTC B1300, B1310, OR B1982: DOOR LOCK ACTUATOR RELAY CIRCUIT FAILURE

Normal Operation
The SJB contains the all lock, passenger unlock, and the driver unlock relays. They are all non-serviceable relays. All 3 relays receive voltage through the bussed electrical center (BEC) fuse 62 (20A) and circuit 1679 (WH/YE). Ground for the relays is provided through circuit 1205 (BK). Based on input from the door lock control switches, keypad, or remote keyless entry (RKE), the SJB grounds the coil side of the relays, which in turn energizes the relay, and sends voltage to the appropriate output.

If the BEC fuse 62 (20A) has failed or is removed, all three DTCs will be present.
- DTC B1300 (Power Door Lock Circuit Failure) - is a continuous and on-demand DTC that sets when the SJB detects no voltage output from the door lock relay, when the relay is energized.
- DTC B1310 (Power Door Unlock Circuit Failure) - is a continuous and on-demand DTC that sets when the SJB detects no voltage output from the passenger door unlock relay, when the relay is energized.
- DTC B1982 (Driver's Door Unlock Relay Circuit Failure) - is a continuous and on-demand DTC that sets when the SJB detects no voltage output from the driver door unlock relay, when the relay is energized.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Lock actuators
- SJB
