[54E] SMART WIRING SYSTEM (SWS) USING SWS MONITOR <Except for Hong Kong spec.> - - INPUT SIGNAL PROCEDURES - INSPECTION PROCEDURE P-15: The driver's door lock actuator switch signal is not received. <LH drive vehicles> | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE P-15: The driver's door lock actuator switch signal is not received. <LH drive vehicles>
| CAUTION Whenever the ECU is replaced, ensure that the input signal circuit is normal.
| COMMENTS ON TROUBLE SYMPTOM Input signal from the driver's door lock actuator is used to operate the functions below. If the signal is abnormal, these functions will not work normally. Key reminder function Central door locking Keyless entry system Room lamps
| POSSIBLE CAUSES Malfunction of the front door lock actuator (LH) Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Connector check: E-11 front door lock actuator (LH) connector Q: Is the check result normal? YES: Go to Step 2. NO: Repair the defective connector.
| Step 2. Check the front door lock actuator (LH). Refer to GROUP 42 - Door . Q: Is the check result normal? YES: Go to Step 3. NO: Replace the front door lock actuator (RH).
| Step 3. Measure the resistance at the E-11 front door lock actuator (LH) connector. Disconnect the connector, and measure at the wiring harness side. Resistance between E-11 front door lock actuator (LH) connector terminal No.1 and body earth OK: 2 Ω or less Q: Is the check result normal? YES: Go to Step 5. NO: Go to Step 4.
| Step 4. Check the wiring harness between E-11 front door lock actuator (LH) connector terminal No.1 and body earth NOTE: Prior to the wiring harness inspection, check intermediate connector C-118, and repair if necessary. Check the earth wires for open circuit. 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: Repair the wiring harness.
| Step 5. Connector check: C-220 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 E-11 front door lock actuator (LH) connector (terminal Nos.2 and 3) and C-220 ETACS-ECU connector (terminal Nos.35 and 36). NOTE: Prior to the wiring harness inspection, check intermediate connector C-118, and repair if necessary. Check the input line for open circuit. Q: Is the check result normal? YES: Go to Step 7. NO: Repair the wiring harness.
| Step 7. Pulse check Check the input signal from the driver's door lock actuator switch.
