ON BOARD SELF-DIAGNOSIS SYSTEM DIAGRAM

ON BOARD SELF-DIAGNOSIS OPERATION PROCEDURE

CAUTION:

Start condition of on board self-diagnosis
• ICC system OFF
• DCA system OFF
• Vehicle speed 0 km/h (0 MPH)
1.

Turn the ignition switch OFF.

2.

Start the engine.

3.

Wait for 5 seconds after starting the engine. Push up the
RESUME/ACCELERATE switch 5 times and push down the
SET/COAST switch 5 times within 10 seconds. 
NOTE:
If the above operation cannot be performed within 10 seconds
after waiting for 5 seconds after starting the engine, repeat the
procedure from step 1. 

4.

The DTC is displayed on the set vehicle speed indicator (1) on the ICC system display on the information
display when the on board self-diagnosis starts. Refer to

• 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.
