CAUTIONCOMMENTS 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 (RH)
- Malfunction of the ETACS-ECU
- Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
Step 3. Measure the resistance at the E-25 front door lock actuator (RH) connector.
- Disconnect the connector, and measure at the wiring harness side.
- Resistance between E-25 front door lock actuator (RH) connector terminal No.3 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-25 front door lock actuator (RH) connector terminal No.3 and body earth
NOTE: Prior to the wiring harness inspection, check intermediate connector C-30, 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 6. Check the wiring harness from E-25 front door lock actuator (RH) connector terminal Nos.1 and 2 to C-220 ETACS-ECU connector terminal Nos.35 and 36.
NOTE: Prior to the wiring harness inspection, check intermediate connector C-30, 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.
