With CONSULT: “How to Erase DTC and 1st Trip DTC” in EC-60, "
CONSULT Function".
Without CONSULT: “How to Erase Self-diagnostic Results” in EC-57, "
On Board Diagnosis Function".
- Study the relationship between the cause detected by DTC and the symptom described by the customer.
(Symptom Table is useful. Refer to EC-464, "
Symptom Table".)
3. Check related service bulletins for information.
Is any symptom described and is any DTC detected?

• Perform Component Function Check if DTC CONF IRMATION PROCEDURE is not included on Service
Manual. This simplified check procedure is an effect ive alternative though DTC cannot be detected during
this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC CONFIR-
MATION PROCEDURE.
Is DTC detected?
YES >> GO TO 10.
