• It displays for up to 5 minutes and then stops.
• If multiple malfunctions exist, up to 6 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.

DIAGNOSIS SYSTEM (ADAS CONTROL UNIT)
NOTE:
• Causes of the maximum five cancellations (system cancel) are displayed.
• The displayed cancellation causes display the number of the ignition switch ON/OFF up to 254. It is fixed to
254 if it is over 254. It returns to 0 when the same cancellation cause is detected again.
