SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)

NHAT0022S01

1.

Turn on CONSULT-II and touch “ENGINE” for OBD-II detected
items or touch “A/T” for TCM self-diagnosis.
If A/T is not displayed, check TCM power supply and ground
circuit. Refer to AT-95. If result is NG, refer to EL-10,
“POWER SUPPLY ROUTING”.

SAT987J

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.
