[54D] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Except for Hong Kong spec.> - - SYMPTOM PROCEDURES - CENTRAL DOOR LOCKING SYSTEM - INSPECTION PROCEDURE C-1: Central door locking system does not work. <RH drive vehicles> | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE C-1: Central door locking system does not work. <RH drive vehicles>
| CAUTION Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.
| COMMENTS ON TROUBLE SYMPTOM If the central door locking system does not work at all, the driver's door lock actuator or the ETACS-ECU may be defective.
| POSSIBLE CAUSES Malfunction of the driver's door lock actuator Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Check the power supply circuit. When the ignition switch is turned to the LOCK (OFF) position, check if the hazard warning lamps illuminate. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to Inspection Procedure A-2 "Check the ETACS-ECU battery power supply circuit ."
| Step 2. Pulse check Check the input signal from the driver's door lock actuator switch.
System switch | Check condition
--- | ---
Driver's door lock actuator switch | When the driver's key cylinder or inside lock knob is unlocked or locked
OK: The MUT-II/III sounds or the voltmeter needle fluctuates. Q: Is the check result normal? YES: Go to Step 3. NO: Refer to Inspection Procedure P-13 "The driver's door lock actuator signal is not received ."
| Step 3. Connector check: E-25 driver's door lock actuator connector Q: Is the check result normal? YES: Go to Step 4. NO: Repair the defective connector.
| Step 4. Driver's door lock actuator check Check that the driver's door lock actuator works normally. Refer to GROUP 42 - Door . Q: Is the check result normal? YES: Go to Step 5. NO: Replace the driver's door lock actuator.
| Step 5. Connector check: C-217 ETACS-ECU connector Q: Is the check result normal? YES: Go to Step 6. NO: Repair the defective connector.
| Step 6. Check the wiring harness between C-217 ETACS-ECU connector terminal No.20 and fusible link (1). NOTE: Prior to the wiring harness inspection, check intermediate connectors A-14, C-125 and junction block connector C-204, and repair if necessary. Check the power supply line for open circuit. Q: Is the check result normal? YES: Go to Step 7. NO: Repair the wiring harness.
| Step 7. Retest the system. Check that the central door locking system works normally. Q: Is the check result normal? YES: The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ). NO: Replace the ETACS-ECU.
