SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)
1. Turn on CONSULT-II and touch “ENGINE” for EURO-OBD
detected items or touch “A/T” for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground cir-
cuit. Refer to AT- 9 4 , "
TCM Terminals and Reference Value" . If
result is NG, refer to PG-2, "
POWER SUPPLY ROUTING" .
2. Touch “SELF DIAGNOSIS”.
Display shows malfunction experienced since the last erasing
operation.
CONSULT-II performs “real time diagnosis”.
Also, any malfunction detected while in this mode will be dis-
played at real time.
