YES:

Go to Step 11.

NO:

Go to Step 9.

STEP 9. Check ETACS-ECU connector C-301 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is ETACS-ECU connector C-301 in good condition?

YES:

Go to Step 10.

NO:

Repair or replace the connector. Refer to GROUP 00E,

Harness Connector Inspection P.00E-2. Check that the rear
window defogger system works normally.

STEP 10. Check the wiring harness between rear window
defogger relay connector C-306 (terminal 1) and ETACS-
ECU C-301 (terminal 12).

Q:Is the wiring harness between rear window defogger relay

connector C-306 (terminal 1) and ETACS-ECU C-301

(terminal 12) in good condition?

YES:

Check that the rear window defogger system works

normally.

NO:

Repair the wiring harness. Check that the rear window

defogger system works normally.

STEP 11. Check the wiring harness between rear window
defogger relay connector C-306 (terminal 2) and A/C-ECU
connector C-119 (terminal 6).

Q:Is the wiring harness between rear window defogger relay

connector C-306 (terminal 2) and A/C-ECU connector

C-119 (terminal 6) in good condition?

YES:

Go to Step 12.

NO:

Repair or replace the wiring harness. Refer to GROUP

00E, Harness Connector Inspection P.00E-2. Check that the
rear window defogger system works normally.

STEP 12. Check the wiring harness between rear window
defogger relay connector C-306 (terminal 3) and rear
window defogger connector F-20 (terminal 1).

NOTE:

Also check intermediate connector C-32 and D-12 for

loose, corroded, or damaged terminals, or terminals pushed
back in the connector. If intermediate connector C-32 and
D-12 is damaged, repair or replace the connector as
described in GROUP 00E, Harness Connector Inspection P.
00E-2.

MANUAL A/C DIAGNOSIS

Q:Is the wiring harness between rear window defogger relay

connector C-306 (terminal 3) and rear window defogger

connector F-20 (terminal 1) in good condition?

YES:

It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

NO:

Repair or replace the wiring harness. Refer to GROUP

00E, Harness Connector Inspection P.00E-2. Check that the
rear window defogger system works normally.

STEP 13. Check rear window defogger connector F-05 for
loose, corroded or damaged terminals, or terminals pushed
back in the connector.

Q:Is rear window defogger connector F-05 in good

condition?

YES:

Go to Step 14.

NO:

Repair or replace the connector. Refer to GROUP 00E,

Harness Connector Inspection P.00E-2. Check that the rear
window defogger system works normally.

STEP 14. Measure the resistance at rear window defogger
connector F-05.

(1)

Disconnect rear window defogger connector F-05, and
measure at the wiring harness side.

AC604249 0002

Harness side: F-05

(2)

Measure the resistance between terminal 1 and ground.

｠

The measured value should be 2 ohms or less.

Q:Does the measured resistance value correspond with this

range?

YES:

Go to Step 16.

NO:

Go to Step 15.

STEP 15. Check the wiring harness between rear window
defogger connector F-05 (terminal 1) and the ground.

Q:Is the wiring harness between rear window defogger

connector F-05 (terminal 1) and the ground in good

condition?

YES:

Check that the rear window defogger system works

normally.

NO:

Repair or replace the wiring harness. Refer to GROUP

00E, Harness Connector Inspection P.00-15. Check that the
rear window defogger system works normally.
