DIAGNOSIS AND REPAIR WORK FLOW

If two or more DTCs are detected, refer to BCS-50, "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 CONFIR MATION 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.

YES >> GO TO 7.
NO >> Monitor input data from related sensors or check voltage of related module terminals using CON- SULT.
