Inspection Procedure O-9

The driver's or passenger's door lock key cylinder switch is not sent to the ETACS-ECU.

Driver's Or Passenger's Door Lock Key Cylinder Switch Input Circuit:




Connectors:






CIRCUIT OPERATION
The ETACS-ECU uses the input signals from the driver's and passengers door lock key cylinder switch to operate the following devices or functions.

TECHNICAL DESCRIPTION (COMMENT)
The driver's and passenger's door lock key cylinder switch input signals is used to operate the following devices or functions:
- Central door locking system
- Theft-alarm system

If the signal fails, these devices will not work normally.

TROUBLESHOOTING HINTS
- Malfunction of the driver's or passenger's door lock key cylinder switch
- Malfunction of the ETACS-ECU
- Damaged harness wires or connectors

DIAGNOSIS

Required Special Tools:
- MB91223: Test Harness Set

- MB991529: Diagnostic Trouble Code Check Harness

STEP 1. Check the location of malfunction.

Q: Which door key switch signal is not input?

Driver's door: Go to Step 2.
Passenger's door: Go to Step 8.







STEP 2. Check the driver's door lock key cylinder switch.

Q: Is the driver's door lock key cylinder switch in good condition?

YES: Go to Step 3.
NO: Replace it. The input signal from the driver's door lock key cylinder switch should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.

STEP 3. Check the driver's door lock key cylinder switch ground circuit at driver's door lock key cylinder switch connector E-14.
1. Disconnect driver's door lock key cylinder switch connector E-14 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 6.
NO: Go to Step 4.




STEP 4. Check driver's door lock key cylinder switch connector E-14 for damage.

Q: Is driver's door lock key cylinder switch connector E-14 in good condition?

YES: Go to Step 5.
NO: Repair or replace it. Refer to Harness Connector Inspection. The input signal from the driver's door lock key cylinder switch should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.




STEP 5. Check the harness wires between driver's door lock key cylinder switch connector E-14 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 driver's door lock key cylinder switch connector E-14 and ground in good condition?

YES: There is no action to be taken.
NO: Repair them. The input signal from the driver's door lock key cylinder switch should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.







STEP 6. Check the driver's door lock key cylinder switch connector E-14 and ETACS-ECU connector C-312 for damage.

Q: Are driver's door lock key cylinder switch connector E-14 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 input signal from the driver's door lock key cylinder switch should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.







STEP 7. Check the harness wires between driver's door lock key cylinder switch connector E-14 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 driver's door lock key cylinder switch connector E-14 and ETACS-ECU connector C-312 in good condition?

YES: Replace the ETACS-ECU. The input signal from the driver's door lock key cylinder switch should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.
NO: Repair them. The input signal from the driver's door lock key cylinder switch should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.







STEP 8. Check the passenger's door lock key cylinder switch.

Q: Is the passenger's door lock key cylinder switch in good condition?

YES: Go to Step 9.
NO: Replace it. The input signal from the passenger's door lock key cylinder switch should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.

STEP 9. Check the passenger's door lock key cylinder switch ground circuit at driver's door lock key cylinder switch connector E-06.
1. Disconnect passenger's door lock key cylinder switch connector E-06 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 passengers door lock key cylinder switch connector E-06 for damage.

Q: Is passenger's door lock key cylinder switch connector E-06 in good condition?

YES: Go to Step 11.
NO: Repair or replace it. Refer to Harness Connector Inspection. The input signal from the passenger's door lock key cylinder switch should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.




STEP 11. Check the harness wires between passenger's door lock key cylinder switch connector E-06 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 passenger's door lock key cylinder switch connector E-06 and ground in good condition?

YES: There is no action to be taken.
NO: Repair them. The input signal from the passenger's door lock key cylinder switch should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.







STEP 12. Check the passenger's door lock key cylinder switch connector E-06 and ETACS-ECU connector C-312 for damage.

Q: Are passenger's door lock key cylinder switch connector E-06 and ETACS-ECU connector C-312 in good condition?

YES: Go to Step 13.
