DIAGNOSIS SYSTEM (ICC SENSOR INTEGRATED UNIT)

• If multiple malfunctions exist, up to 3 DTCs can be stored in memory at the most, and the most recent

one is displayed first. 

WHEN THE ON BOARD SELF-DIAGNOSIS DOES NOT START

If the on board self-diagnosis does not start, check the following items.

HOW TO ERASE ON BOARD SELF-DIAGNOSIS

1.

Turn the ignition switch OFF.

2.

Start the engine, and then start the on board self-diagnosis. 

3.

Press the CANCEL switch 5 times, and then press the DIS-
TANCE switch 5 times under the condition that the on board
self-diagnosis starts. 
NOTE:
• Complete the operation within 10 seconds after pressing the

CANCEL switch first. 

• If the operation is not completed within 10 seconds, repeat the

procedure from step 1. 

4.

DTC 55 is displayed after erasing.
NOTE:
DTCs for existing malfunction can not be erased. 

5.

Turn ignition switch OFF, and finish the diagnosis.
