[54D] SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR <Except for Hong Kong spec.> - - INPUT SIGNAL PROCEDURES - INSPECTION PROCEDURE P-19: The front passenger’s door lock key cylinder switch signal is not detected. <RH drive vehicles> | PRINT PAGE / INDEX / PRIOR / NEXT

INSPECTION PROCEDURE P-19: The front passenger’s door lock key cylinder switch signal is not detected. <RH drive vehicles>
| CAUTION Whenever the ECU is replaced, ensure that the input signal circuit is normal.
| COMMENTS ON TROUBLE SYMPTOM Input signal from the front passenger's door lock key cylinder switch is used to operate the central door locking function. If the signal is abnormal, the central door locking function will not work normally.
| POSSIBLE CAUSES Malfunction of the front passenger's door lock key cylinder switch Malfunction of the ETACS-ECU Damaged harness wires and connectors
| DIAGNOSIS PROCEDURE
| Step 1. Connector check: E-04 door lock key cylinder switch (LH) connector Q: Is the check result normal? YES: Go to Step 2. NO: Repair the defective connector.
| Step 2. Check the door lock key cylinder switch (LH). Refer to GROUP 42 - Door . Q: Is the check result normal? YES: Go to Step 3. NO: Replace the door lock key cylinder switch (LH).
| Step 3. Measure the resistance at the E-04 door lock key cylinder switch (LH) connector. Disconnect the connector, and measure at the wiring harness side. Resistance between E-04 door lock key cylinder switch (LH) connector terminal No.2 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-04 door lock key cylinder switch (LH) connector terminal No.2 and body earth. NOTE: Prior to the wiring harness inspection, check intermediate connector C-34, and repair if necessary. Check the earth wires for open circuit. Q: Is the check result normal? YES: 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 from E-04 door lock key cylinder switch (LH) connector terminal Nos.1 and 3 to C-220 ETACS-ECU connector terminal Nos.27 and 28. NOTE: Prior to the wiring harness inspection, check intermediate connector C-34, 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. Retest the system. Check that the passenger's door lock key cylinder switch signal is received normally. Q: Is the check result normal? YES: Intermittent malfunction. (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ). NO: Replace the ETACS-ECU.
