If two or more DTCs are detected, refer to
BCS-61, "DTC Inspection Priority Chart"
, and determine trouble
diagnosis order.
NOTE:

Instruction. 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.
