Malfunction Indicator lamp (MIL)ECS004QL
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.
lIf the malfunction indicator does not light up, refer to "",
“Warning Lamps”.
(Or see MIL & CONSULT-II in EC section. Refer toEC-48,
"Malfunction Indicator (MI)", “Description”, “Malfunction Indi-
cator lamp (MIL)” and "", “CONSULT-II”.)
2. When the engine is started, the malfunction indicator should go
off.
If the lamp remains on, the on board diagnostic system has
detected an emission-related (EURO-OBD) malfunction. For
detail, refer to "njec0029", “ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION”.
CONSULT-IIECS0 04 QM
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)”AT- 4 1 , "SELF-DIAGNOSTIC
PROCEDURE (WITH CONSULT-II)", place check marks for results on the “DIAGNOSTIC WORKSHEET”,
AT- 5 7 , "
DIAGNOSTIC WORKSHEET". 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).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, 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 toAT - 1 2 5 , "
TCM Terminals and Reference Value".If
result is NG, refer toPG-2, "
POWER SUPPLY ROUTING".

MULTI-REMOTE CONTROL SYSTEM
lthrough multi-remote control unit terminal 5
lto time control unit terminal 32.
Then time control unit operates to lock doors and set super lock (models with super lock).
UNLOCK OPERATION
When the UNLOCK signal is input to multi-remote control unit (the antenna of the system is combined with
multi-remote control unit), ground is supplied
lthrough multi-remote control unit terminal 6
lto time control unit terminal 33.
Time control unit operates to unlock driver's door and release super lock (models with super lock).
Then, if an unlock signal is sent from the remote controller again within 5 seconds, all other doors will be
unlocked.
HAZARD REMINDER
When the doors are locked or unlocked by multi-remote controller (signal from driver side unlock sensor), sup-
ply power to hazard warning lamp flashes as follows
lLock operation: Flash once
lUnlock operation: Flash twice
MULTI-REMOTE CONTROLLER ID CODE ENTRY
A maximum of four remote controllers can be entered.
To enter ID code entry, the following signals must be input to the multi-remote control unit.
lIgnition switch (ON)
lSignal from remote controller
For detailed procedure, refer toBL-52, "
ID Code Entry Procedure".
