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-317 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Are driver's door lock key cylinder switch connector E-14 and ETACS-ECU connector C-317 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 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 wiring harness between driver's door lock key cylinder switch connector E-14 (terminal 1 and 3) and ETACS-ECU connector
C-317 (terminal 25 and 42).

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 it. Refer to Harness Connector Inspection.

Q: Are the wiring harness between driver's door lock key cylinder switch connector E-14 (terminal 1 and 3) and ETACS-ECU connector C-317 (terminal 25 and 42) 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 : 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 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 passenger'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 wiring harness side.
