-
Record DTC and freeze frame data (Print them out using CONSULT.)
-
Erase DTC.
-
Study the relationship between the cause detected by DTC and the symptom described by the customer.
3.
Check related service bulletins for information.
Are any symptoms described and any DTC detected?
Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.

If two or more DTCs are detected, refer to
BCS-88, "DTC Inspection Priority Chart"
and determine trouble
diagnosis order.
NOTE:
• Freeze frame data is useful if the DTC is not detected.
• Perform Component Function Check if DTC CONFIRMATION PROCEDURE is not included on Service
Manual. This simplified check procedure is an effective 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 the symptom described?
YES
>> GO TO 7.
NO
>> Monitor input data from related sensors or check voltage of related module terminals using CON-
SULT.
