DTC B1320	Door ajar LF circuit open
DETECTION CONDITION	Open circuit in wiring harness between PJB and front door latch switch (driver-side)
POSSIBLE CAUSE	• Open circuit in wiring harness between PJB terminal J-06 W and front door latch and lock actuator (driver-side) terminal G • Front door latch and lock actuator malfunction • PJB malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT FRONT DOOR LATCH AND LOCK ACTUATOR (DRIVER-SIDE) CONNECTOR • Turn the ignition switch off. • Disconnect the front door latch and lock actuator (driver-side) connector. • Inspect the front door latch and lock actuator (driver-side) connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 5.
1		No	Go to the next step.
2	INSPECT PJB CONNECTOR • Disconnect the PJB connector. • Inspect the PJB connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 5.
2		No	Go to the next step.
3	INSPECT FRONT DOOR LATCH AND LOCK ACTUATOR (DRIVER-SIDE) SIGNAL CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between PJB terminal J-06 W (wiring harness-side) and front door latch and lock actuator (driver-side) terminal G (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
3		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 5.
4	INSPECT FRONT DOOR LATCH AND LOCK ACTUATOR (DRIVER-SIDE) • Inspect the front door latch and lock actuator (driver-side). (See FRONT DOOR LATCH AND LOCK ACTUATOR INSPECTION.) • Is there any malfunction?	Yes	Replace the front door latch and lock actuator (driver-side), then go to the next step. (See FRONT DOOR LATCH AND LOCK ACTUATOR REMOVAL/INSTALLATION.)
4		No	Go to the next step.
5	VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PJB memory using the M-MDS. • Perform the self-test. (See PJB SELF-TEST[PJB].) • Is the same DTC present?	Yes	Replace the PJB. (See PASSENGER JUNCTION BOX (PJB) REMOVAL/INSTALLATION.)
5		No	DTC troubleshooting completed.
