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-1484,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-1484,
"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-1484, "
Diagnostic Procedure" .
WITHOUT 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-1484,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-1484,
"Diagnostic Procedure" .
3. Start engine.
Be careful not to overheat engine.
4. Set temperature control lever to full cold position.
5. Turn air conditioner switch ON.
6. Turn blower fan switch ON.
7. Run engine at idle for a few minutes with air conditioner operating.
Be careful not to overheat engine.

DTC P0217 ENGINE OVER TEMPERATURE

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic ProcedureEBS0120B
1. CHECK COOLING FAN LOW SPEED OPERATION
With CONSULT-II
1. Disconnect cooling fan relays -2 and -3.
2. Turn ignition switch ON.
3. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II and touch “LOW” on the CONSULT-II screen.
4. Make sure that cooling fans-1 and -2 operate at low speed.
OK or NG
OK >> GO TO 2.
NG >> Check cooling fan low speed control circuit. (Go to EC-
1487, "PROCEDURE A" .)
