Inspection Procedure O-10


INSPECTION PROCEDURE O-10: The driver's or passenger's door lock actuator switch is not sent to the ETACS-ECU.






CIRCUIT OPERATION
The ETACS-ECU uses the input signal from the driver's, passenger's, rear and back door lock actuator switch to operate the following functions.

TECHNICAL DESCRIPTION (COMMENT)

The input signal from the driver's door lock actuator switch is used to operate the following systems or functions:
- Central door locking system
- Forgotten key prevention function .
- Rolling lock function
- Keyless entry system
- Interior light dimming function
- Theft-alarm system
If the signal fails, these systems or function will not work normally.


TECHNICAL DESCRIPTION (COMMENT)

The input signal from the passenger's door lock actuator switch is used to operate the following systems or functions:

Q: Is driver's door lock actuator switch connector E-13 in good condition?

YES : Go to Step 7.

NO : Repair or replace the damaged component(s). Refer to Harness Connector Inspection. The input signal from the driver's door lock actuator 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 wiring harness between driver's door lock actuator switch connector E-13 (terminal 2 and 3) and ETACS-ECU connector
C-317 (terminal 36 and 35).

NOTE: Also check intermediate connector C-211 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If intermediate connector C-211 is damaged, repair or replace the damaged components) as described in Harness Connector Inspection.

Q: Are the wiring harness between driver's door lock actuator switch connector E-13 (terminal 2 and 3) and ETACS-ECU connector C-317
(terminal 36 and 35) in good condition?

YES : Replace the ETACS-ECU. The input signal from the driver's door lock actuator switch should be able to be checked and the functions, which are described in the 'Technical Description (comment),' should work normally.

NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary. The input signal from the driver's door lock actuator switch should be able to be checked and the functions, which are described in the 'Technical Description (comment),' should work normally.
