NO.1 ONE OR MORE ON-BOARD DIAGNOSTIC FUNCTIONS INOPERATIVE[KEYLESS ENTRY SYSTEM]

• When performing an asterisked (*) troubleshooting inspection, slightly shake the wiring harness and connectors while performing the inspection to discover whether poor contact points are the cause of any intermittent malfunctions. If there is a problem, verify that the connectors, terminals and wiring harnesses are connected correctly and undamaged.

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	INSPECT HAZARD WARNING LIGHT OPERATION DURING ON-BOARD DIAGNOSIS • Did hazard warning lights flash during on-board diagnostic function operation?	Yes	Go to Step 3.
No	Go to next step.
2	INSPECT HAZARD WARNING LIGHT CIRCUIT • Do hazard warning lights flash when hazard warning switch is on?	Yes	Go to next step.
No	Inspect hazard warning light circuit.
3	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.
No	Go to the next step.
4	INSPECT DOOR LOCK LINKAGE • Operate the door lock knob and verify the door locks and unlocks manually. • Does every door lock system work?	Yes	Go to the next step.
No	Inspect the door lock linkage.
*5	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.
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.
6	REINSPECT MALFUNCTION SYMPTOM AFTER REPAIR • Does the keyless entry system operate properly?	Yes	• Troubleshooting completed. • Explain repairs to the customer.
No	Reinspect the malfunction symptoms, then repeat from Step 1 if malfunction recurs.
