DTC Detecting Condition and Trouble Area
NOTE
When DTC P0107 and P0532 are indicated together, it is possible that “GRY/RED” wire circuit open.
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool to DLC.
2) Turn ON ignition switch and clear DTC.
3) Make sure that all accessory switch is tuned OFF.
4) Start engine and warm it up to normal operating temperature (ECT approx. 90 – 95 °C, 193 – 203 °F).
5) Increase engine speed to 3000 rpm.
6) In this state, Turn ON following accessory switch.
• Head lights switch.
• Blower motor switch (max position).
• Rear defogger switch.
7) Decrease engine speed to idle.
8) Check DTC and pending DTC.
