1	One or more on-board diagnostic functions inoperative
DESCRIPTION	• Malfunction in door lock linkage system
POSSIBLE CAUSE	• Malfunction in door lock linkage • Malfunction in PJB door lock/unlock signal circuit - PJB malfunction


STEP	INSPECTION		ACTION
1	VERIFY THAT ALL DOORS LOCK AND UNLOCK DURING ON-BOARD DIAGNOSIS • Do all doors unlock and lock during on-board diagnostic function operation?	Yes	Reinspect the malfunction symptoms, then repeat from Step 1 if the malfunction recurs.

2		No	Inspect the door lock linkage.
*3	INSPECT IF MALFUNCTION IS IN DOOR LOCK ACTUATOR, PJB GROUND CIRCUIT OR ELSEWHERE • Measure the voltage at PJB terminals J-05 AP, and J-05 Y. - All doors locked: Cycles 1.0 V or less → B+ → 1.0 V or less (terminal J-05 AP) - All doors unlocked: Cycles B+ → 1.0 V or less → B+ (J-05 Y) • Is the voltage as above?	Yes	Reinspect the malfunction symptoms, then repeat from Step 1 if the malfunction recurs.
*3		No	• Inspect the PJB connector. • Inspect the wiring harness between the PJB and door lock actuator. - If the above parts are normal, go to the next step. - If any of above parts are malfunctioning, repair the malfunctioning part.
4	REINSPECT MALFUNCTION SYMPTOM AFTER REPAIR • Does the keyless entry system operate properly?	Yes	• Troubleshooting completed. • Explain repairs to the customer.
