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.
