OK: 2

Ω or less

Q: Is the check result normal?

YES :

Go to Step 31.

NO :

Go to Step 30.

Step 30. Check the wiring harness from E-09 rear
power window regulator motor (LH) connector
terminal No.5 to body earth.

NOTE:

Prior to the wiring harness inspection, check interme-
diate connector D-15, and repair if necessary.

• Check the input and output lines to the revolution

detection sensor for open or short circuit.

Q: Is the check result normal?

window sub switch (LH) connector

Q: Is the check result normal?

YES :

Go to Step 32.

NO :

Repair the defective connector.

Step 32. Check the wiring harness from E-08 rear
power window sub switch (LH) connector
terminal Nos.8, 2 and 3 to E-09 rear power
window regulator motor (LH) connector terminal
Nos.3, 2 and 6.

• Check the input and output lines to the revolution

detection sensor for open or short circuit.

Q: Is the check result normal?

YES :

Go to Step 33.

NO :

Repair the wiring harness.

Step 33. Retest the system.
After the rear power window sub switch (LH) is
replaced, check that the rear left door anti-trap func-
tion can be operated by the power window sub
switch.
(1) Replace the rear power window sub switch (LH).
(2) Check that the rear left power window anti-trap

function works.

Q: Is the check result normal?

KEYLESS ENTRY SYSTEM

INSPECTION PROCEDURE E-1: Keyless entry system does not work.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM

If the keyless entry system does not work normally,
the input signal circuits to the components below or
the ETACS-ECU may be defective.

• Key reminder switch

• All of the door switches

• Keyless entry transmitter

• Driver's door lock actuator

POSSIBLE CAUSES

• Malfunction of the key reminder switch

• Malfunction of the door switches

• Malfunction of the keyless entry transmitter

• Malfunction of the driver's door lock actuator

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Check the power supply circuit.
When the ignition switch is turned to the LOCK
(OFF) position, check if the hazard warning lamps
illuminate.

Q: Is the check result normal?

YES :

Go to Step 2.
