Terminals and Reference Values for TCM

TCM terminal data are reference values, measured between each terminal and ground.












CONSULT Function (TRANSMISSION)

CONSULT can display each diagnostic item using the diagnostic test models shown following.

FUNCTION







CONSULT REFERENCE VALUE

NOTICE:
1.The CONSULT electrically displays shift timing and lock-up timing (that is, operation timing of each solenoid).
Check for time difference between actual shift timing and the CONSULT 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 and that indicated in Service Manual 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 indicates the point where shifts are completed.
3.Shift solenoid valve "A" or "B" is displayed on CONSULT at the start of shifting. Gear position is displayed upon completion of shifting (which is computed by TCM).

Diagnosis Procedure without CONSULT


TCM SELF-DIAGNOSTIC PROCEDURE

Description
If a malfunction occurs in electrical system, turning ignition switch ON will illuminate OD OFF indicator lamp for
2 seconds. To detect a malfunction, entering a self-diagnosis start signal retrieves information on malfunctions from memory and indicates malfunction by blinking OD OFF indicator lamp.
Diagnostic Procedure

1. CHECK OD OFF INDICATOR LAMP

1.Park vehicle on flat surface.





2.Move selector lever to "P" position.
3.Turn ignition switch OFF. Wait at least 5 seconds.





4.Turn ignition switch ON. (Do not start engine.)
Does OD OFF indicator lamp come on about 2 seconds?
YES- GO TO 2.
NO- Stop procedure. "OD OFF Indicator Lamp Does Not Come On" before proceeding.

2. JUDGEMENT PROCEDURE STEP 1

1.Turn ignition switch OFF.
2.Keep pressing shift lock release button.
3.Move selector lever from "P" to "D" position.
4.Turn ignition switch ON. (Do not start engine.)
5.Keep pressing overdrive control switch while OD OFF indicator lamp is lighting up for 2 seconds. (OD
OFF indicator lamp is on.)
6.Keep pressing overdrive control switch and shift selector lever to the "2" position. (OD OFF indicator lamp is on.)
7.Stop pressing overdrive control switch. (OD OFF indicator lamp is on.)
8.Shift selector lever to the "1" position. (OD OFF indicator lamp is on.)
9.Keep pressing overdrive control switch. (OD OFF indicator lamp is off.)
10.Depress accelerator pedal fully while pressing overdrive control switch.
- GO TO 3.

3. CHECK SELF-DIAGNOSIS CODE

Check OD OFF indicator lamp. Refer to "Judgement of Self-diagnosis Code" .

How to Erase Self-diagnostic Results
1.If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait for at least
5 seconds and then turn it ON again.
2.Perform "Diagnostic Procedure Without CONSULT" .
3.Turn ignition switch OFF. (The self-diagnostic results will be erased.)
