Inspection with CONSULT-II (Self-Diagnosis)

EKS00G8M

CAUTION:

If a CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on which control unit(s) carries out CAN communication.

1.

SELF-DIAGNOSIS RESULT CHECK

1.

Connect CONSULT-II and select "IPDM E/R" on the "SELECT SYSTEM".

2.

Select "SELF-DIAG RESULTS" on the "SELECT DIAG MODE" screen.

3.

Check display content in self-diagnosis results.

NOTE:
The Details for Display for the Period are as follows:

●

CRNT: Error currently detected by IPDM E/R.

●

PAST: Error detected in the past and stored in IPDM E/R memory.

Contents displayed

NO DTC DETECTED. FURTHER TESTING MAY BE REQUIRED.>>INSPECTION END.
