STEP 14. Connector check: F-06 rear window
defogger connectorQ: Is the check result normal?
YES :
Go to Step 15.
NO : Repair the connector.
STEP 15. Resistance measurement at F-06 rear
window defogger connector.
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Measure the resistance value between terminal 1
and earth.
OK: 2 ohms or less
Q: Is the check result normal?
YES :
Go to Step 17.
NO : Go to Step 16.

STEP 16. Check the wiring harness between F-06
rear window defogger connector terminal No.1
and earth.
•Check the rear window defogger earth line for
open circuit.Q: Is the check result normal?
YES :
The trouble can be an intermittent
malfunction (Refer to GROUP 00, How to
Cope with Intermittent Malfunction P.00-5).
NO : Repair the wiring harness.
STEP 17. Check the rear window defogger.
Refer to GROUP 54A, Rear window defogger
P.54A-96.
Q: Does the rear window defogger work normally?
YES :
Replace the manual air conditioner control
panel (A/C-ECU) or the heater control unit.
NO : Repair the rear window defogger.
INSPECTION PROCEDURE 8: Rear Window Defogger Timer Function does not Operate.
COMMENTS ON TROUBLE SYMPTOM
Turn ON the rear window defogger switch. If the rear
window defogger does not shut off after roughly 11
minutes then the rear window defogger timer is
malfunctioning.
TROUBLESHOOTING HINTS
•Malfunction of the manual air conditioner control
panel (A/C-ECU) or the heater control unit
DIAGNOSIS
Check the performance of the rear window
defogger timer operations.
(1) Turn the ignition switch to the "ON" position.
(2) Turn the rear window defogger switch to the "ON"
position (operate for approx. 11 minutes)
Q: Does the rear window defogger timer function
work normally?
YES :
Intermittent malfunction
NO : Replace the manual air conditioner control
panel (A/C-ECU) or the heater control unit.

ON-VEHICLE SERVICE
HEATER, AIR CONDITIONER AND VENTILATION55-73
PERFORMANCE TEST M1552001400355
1. The vehicles to be tested should be in a place that
is not in direct sunlight.
2. Close the high and low-pressure valve of the
gauge manifold.
3. Connect the charging hose (blue) to the
low-pressure valve and connect the charging
hose (red) to the high-pressure valve of the gauge
manifold.
CAUTION
•To connect the quick joint, press section A
firmly against the service valve until a click is
heard.
•When connecting, run your hand along the
hose while pressing to ensure that there are
no bends in the hose.
4. Install the quick joint (for low-pressure) to the
charging hose (blue), and connect the quick joint
(for high-pressure) to the charging hose (red).NOTE: The high-pressure service valve is on the
A/C pipe and the low-pressure service valve is on
the suction hose.
5. Connect the quick joint (for low-pressure) to the
low-pressure service valve and connect the quick
joint (for high-pressure) to the high-pressure
service valve.
6. Start the engine.
7. Set the A/C controls as follows:
•A/C switch: A/C − ON position
•Mode selection: FACE position
•Temperature control: MAXIMUM COOLING
position
•Air selection: RECIRCULATION position
•Blower switch: "4" (Fast) position
8. Keep engine speed to idling speed with A/C clutch
engaged.
9. Engine should be warmed up with doors and all
windows opened.
10.Insert a thermometer in the centre air outlet and
operate the engine for 20 minutes.
NOTE: If the clutch cycles, take the reading before
the clutch disengages.
11.Note the discharge air temperature.
