On Board Diagnosis LogicEBS01208
Overall Function CheckEBS01209
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could be caused by high
pressure fluid escaping from the radiator.

Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-1323,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-1323,
"Diagnostic Procedure" .
3. Turn ignition switch ON.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II.
5. If the results are NG, go to EC-1323, "
Diagnostic Procedure" .

6. Check A/T fluid condition.

If A/T fluid is very dark or smells burned, checking operation
of A/T. Flush cooling system after repair of A/T.

If A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-12,
"RADIATOR" , CO-14, "RADIATOR (ALUMINUM TYPE)" .
7. Install the removed A/T fluid level gauge in the A/T fluid charging
pipe.
CAUTION:
Firmly fix the A/T fluid level gauge to the A/T fluid charging
pipe using a stopper attached.
Changing A/T FluidECS004Q8
1. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid from drain plug and refill with new A/T fluid. Always refill same volume with drained fluid.
Refer to MA-17, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
CAUTION:
Do not reuse drain plug gasket.
4. Run engine at idle speed for five minutes.
5. Check A/T fluid level and condition. Refer to AT- 1 6 , "
Checking
A/T Fluid" . If A/T fluid is still dirty, repeat steps 2 through 5.

4. Set manual shaft to position P.
5. Remove park/neutral position (PNP) switch.
6. Remove bracket from transaxle case.
7. Remove revolution sensor from transaxle case.
8. Remove O-ring from revolution sensor.
9. Remove oil pan and oil pan gasket.

Do not reuse oil pan bolts.
10. Check foreign materials in oil pan to help determine causes of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-12, "
RADIATOR" .
11. Remove magnets from oil pan.
12. Remove control valve assembly according to the following procedures.
a. Remove snap ring from terminal body.
b. Push terminal body into transaxle case and draw out terminal
cord assembly.
