STEP 13. Check the harness wires between power window
sub switch connector E-05 and ETACS-ECU connector C-
81.
NOTE: After checking intermediate connector C-72, check the
wires. If intermediate connector C-72 is damaged, repair or
replace it. Refer to GROUP 00E, Harness Connector
Inspection

P.00E-2

.

Q: Are the harness wires between power window sub

switch connector E-05 and ETACS-ECU connector C-81
in good condition?
YES : Replace the ETACS-ECU. The door lock switch input

signal should be able to be checked and the central
door locking system should work normally.

NO : Repair them. The door lock switch input signal should

be able to be checked and the central door locking
system should work normally.

STEP 2. Check the hood switch ground circuit at the hood
switch connector A-25.
(1)Disconnect the hood switch connector A-25 and measure at

the harness side.

(2)Measure the resistance between terminal 1 and ground.

Q: Is the resistance less than 2 ohm?

YES : Go to Step 5.
NO : Go to Step 3.

STEP 3. Check hood switch connector A-25 for damage.
Q: Is hood switch connector A-25 in good condition?

YES : Go to Step 4.
NO : Repair or replace it. Refer to GROUP 00E, Harness

. The hood switch input

signal should be able to be checked and the theft-
alarm system should work normally.

STEP 4. Check the harness wires between hood switch
connector A-25 and ground.
Q: Are the harness wires between hood switch connector

A-25 and ground in good condition?
YES : There is no action to be taken.
