Inspection Procedure O-8

The driver's or passenger's door switch or door switches signal is not sent to the ETACS-ECU.

Driver's Or Passenger's Door Switch Input Circuit:




Connectors:






CIRCUIT OPERATION
The ETACS-ECU operates various functions according to the input signal from the driver's or passenger's door switch.

TECHNICAL DESCRIPTION (COMMENT)
The driver's and passenger's door switch and door switches are used to operate the following devices or systems:
- Ignition key reminder tone alarm function (driver's door switch only)
- Light reminder tone alarm function (driver's door switch only)
- Door ajar tone alarm function
- Forgotten key prevention function
- Power window timer function
- Keyless entry system
- Sunroof timer function
- Door ajar warning light
- Interior light
- Theft-alarm system

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

TROUBLESHOOTING HINTS
- Malfunction of the driver's or passenger's door 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 door switch.

Q: Is the door switch in good condition?

YES: Go to Step 2.
NO: Replace it. The driver's and passenger's door switch and door switches input signal should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.




STEP 2. Check the door switch installation state.

NOTE: The door switch is grounded to the body through the mounting screws.

Remove the cap and measure the resistance between the lower metal part and the ground.

Q: Is the resistance less than 2 ohm?

YES: Go to Step 3.
NO: Check the installation state and repair. The driver's and passenger's door switch and door switches input signal should be able to be checked and the functions, which are described in the "Technical Description (comment)," should work normally.

STEP 3. Check the location of malfunction.

Q: Which door switch signal is not input?

Driver's door: Go to Step 4.
Passenger's door: Go to Step 6.







STEP 4. Check driver's door switch connector D-13 and ETACS-ECU connector C-311 for damage.

Q: Are driver's door switch connector D-13 and ETACS-ECU connector C-311 in good condition?

YES: Go to Step 5.
NO: Repair or replace them. Refer to Harness Connector Inspection. The driver's door switch input signal 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 switch connector D-13 and ETACS-ECU connector C-311.

NOTE: After checking junction block connector C-314, check the wires. If junction block connector C-314 are damaged, repair or replace it. Refer to Harness Connector Inspection.

Q: Is the harness wires between the driver's door switch connector D-13 and ETACS-ECU connector C-311 in good condition?

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







STEP 6. Check passenger's door switch connector D-21 and ETACS-ECU connectors C-311 and C-313 for damage.

Q: Are front passenger's door switch connector D-21 and ETACS-ECU connectors C-311 and C-313 in good condition?

YES: Go to Step 7.
NO: Repair or replace them. Refer to Harness Connector Inspection. The passenger's door switch input signal 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 passenger's door switch connector D-21 and ETACS-ECU connectors C-311 and C-313.

NOTE: After checking intermediate connector C-210 and junction block connector C-314, check the wires. If intermediate connector C-210 and junction block connector C-314 are damaged, repair or replace them. Refer to Harness Connector Inspection.

Q: Are the harness wires between passenger's door switch connector D-21 and ETACS-ECU connector C-311 and C-313 in good condition?

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