Specification data are reference valves, and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION

Malfunction Indicator (MI)ECS004QL
1. The malfunction indicator 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 DI-35,
"Schematic" .
(Or see MI & CONSULT-II in EC section. Refer to EC-64,
"Malfunction Indicator (MI)" (WITH EURO-OBD) or EC-568,
"Malfunction Indicator (MI)" (WITHOUT EURO-OBD) or EC-
103, "CONSULT-II Function (ENGINE)" (WITH EURO-OBD)
or EC-604, "
CONSULT-II Function (ENGINE)" (WITHOUT
EURO-OBD).
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 EC-52, "
ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
CONSULT-IIECS004QM
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” AT- 4 5 , place check marks for
results on the “DIAGNOSTIC WORKSHEET”, AT- 5 8
. 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.
