DTC P1217 ENGINE
OVER TEMPERATURE
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the reser voir tank or 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-III
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-890," Diagnosis Procedure " or
EC-890, " Diagnosis Procedure " .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-890," Diagnosis Procedure " or
EC-890, " Diagnosis Procedure " .
3. Turn ignition switch ON.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON- SULT-III.

Power supply for the throttle control motor is provided to the ECM via throttle control motor relay. The throttle
control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends
an ON signal to throttle control motor relay and batte ry voltage is provided to the ECM. When the ignition
switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not
provided to the ECM.
