Malfunction Indicator (MI)ECS007NR
1. The malfunction indicator lamp will light up when the ignition
switch is turned ON without the engine running. This is for
checking the lamp.
●If the malfunction indicator does not light up, refer to EC-397
or EC-715 .
(Or see MI & CONSULT-II in EC section. Refer to EC-49
, EC-
87 .
2. When the engine is started, the malfunction indicator should
turned OFF.
If the lamp remains ON, the on board diagnostic system has
detected an emission-related (EURO-OBD) malfunction. For
detail, refer to EC-36.
CONSULT-IIECS007NS
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” AT- 4 1 , place check marks for
results on the “DIAGNOSTIC WORKSHEET”, AT- 5 7
. Reference pages are provided following the items.
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid valve).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoid valves, sensors, etc.) may be malfunctioning. Check
mechanical parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.
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- 1 0 6 , "
TCM Terminals and Reference Value" . If
result is NG, refer to EL-11, "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.
