Inspection Procedure O-11

The door lock switch (incorporated in power window main switch and power window sub switch) signal is not sent to the ETACS-ECU.

Door Lock Switch Input Circuit:




Connectors:






CIRCUIT OPERATION
The ETACS-ECU uses the input signal from the door lock switch to operate the central door locking system.

TECHNICAL DESCRIPTION (COMMENT)
The door lock switch input signal is used to operate the central door locking system. If the signal fails, the door will not be locked or unlocked when the door lock switch is operated.

TROUBLESHOOTING HINTS
- Malfunction of the power window main switch or power window sub switch (door lock switch)
- Malfunction of the ETACS-ECU
- Damaged harness wires or connectors

DIAGNOSIS

Required Special Tools:
- MB991223: Test Harness Set
- MB991502: Scan Tool (MUT-II)
- MB991529: Diagnostic Trouble Code Check Harness

STEP 1. Check the location of malfunction.

Q: Which door lock switch signal is not Input?

Power window main switch (Driver's door): Go to Step 2.
Power window sub switch (Passenger's door): Go to Step 8.







STEP 2. Check the door lock switch (power window main switch).

Q: Is the door lock switch (power window main switch) in good condition?

YES: Go to Step 3.
NO: Replace the power window main switch. The door lock switch input signal should be able to be checked and the central door locking system should work normally.

STEP 3. Check the power window main switch ground circuit at power window main switch connector E-12.
1. Disconnect power window main switch connector E-12 and measure at the harness side.




2. Measure the resistance between terminal 9 and ground.

Q: Is the resistance less than 2 ohm?

YES: Go to Step 6.
NO: Go to Step 4.




STEP 4. Check power window main switch connector E-12 for damage.

Q: Is power window main switch connector E-12 in good condition?

YES: Go to Step 5.
NO: Repair or replace it. Refer to Harness Connector Inspection. The door lock switch input signal should be able to be checked and the central door locking system should work normally.




STEP 5. Check the harness wires between power window main switch connector E-12 and ground.






NOTE: After checking intermediate connector C-211, check the wires. If intermediate connector C-211 is damaged, repair or replace it. Refer to Harness Connector Inspection.

Q: Are the harness wires between power window main switch connector E-12 and ground in good condition?

YES: There is no action to be taken.
NO: Repair them. The door lock switch input signal should be able to be checked and the central door locking system should work normally.







STEP 6. Check the power window main switch connector E-12 and ETACS-ECU connector C-312 for damage.

Q: Are power window main switch connector E-12 and ETACS-ECU connector C-312 in good condition?

YES: Go to Step 7.
NO: Repair or replace them. Refer to Harness Connector Inspection. The door lock switch input signal should be able to be checked and the central door locking system should work normally.







STEP 7. Check the harness wires between power window main switch connector E-12 and ETACS-ECU connector C-312.






NOTE: After checking intermediate connector C-211, check the wires. If intermediate connector C-211 is damaged, repair or replace it. Refer to Harness Connector Inspection.

Q: Are the harness wires between power window main switch connector E-12 and ETACS-ECU connector C-211 in good condition?

YES: Replace the ETACS-ECU. The door lock switch input signal should be able to be checked and the central door locking system should work normally.
NO: Repair them. The door lock switch input signal should be able to be checked and the central door locking system should work normally.







STEP 8. Check the door lock switch (power window sub switch).

Q: Is the door lock switch (power window sub switch) in good condition?

YES: Go to Step 9.
NO: Replace the power window sub switch. The door lock switch input signal should be able to be checked and the central door locking system should work normally.

STEP 9. Check the power window sub switch ground circuit at power window sub switch connector E-05.
1. Disconnect power window sub switch connector E-05 and measure at the harness side.




2. Measure the resistance between terminal 2 and ground.

Q: Is the resistance less than 2 ohm?

YES: Go to Step 12.
NO: Go to Step 10.




STEP 10. Check power window sub switch connector E-05 for damage.

Q: Is power window sub switch connector E-05 in good condition?

YES: Go to Step 11.
NO: Repair or replace it. Refer to Harness Connector Inspection. The door lock switch input signal should be able to be checked and the central door locking system should work normally.




STEP 11. Check the harness wires between power window sub switch connector E-05 and ground.






NOTE: After checking intermediate connector C-213, check the wires. If intermediate connector C-213 is damaged, repair or replace it. Refer to Harness Connector Inspection.

Q: Are the harness wires between power window sub switch connector E-05 and ground in good condition?

YES: There is no action to be taken.
NO: Repair them. The door lock switch input signal should be able to be checked and the central door locking system should work normally.







STEP 12. Check the power window sub switch connector E-05 and ETACS-ECU connector C-312 for damage.

YES: Go to Step 13.
NO: Repair or replace them. Refer to Harness Connector Inspection. The door lock switch input signal should be able to be checked and the central door locking system should work normally.







STEP 13. Check the harness wires between power window sub switch connector E-05 and ETACS-ECU connector C-312.






NOTE: After checking intermediate connector C-213, check the wires. If intermediate connector C-213 is damaged, repair or replace it. Refer to Harness Connector Inspection.

Q: Are the harness wires between power window sub switch connector E-05 and ETACS-ECU connector C-312 in good condition?

YES: Replace the ETACS-ECU. The door lock switch input signal should be able to be checked and the central door locking system should work normally.
NO: Repair them. The door lock switch input signal should be able to be checked and the central door locking system should work normally.
