TROUBLE DIAGNOSIS
Check for time difference between actual shift timing and the CONSULT-III display. If the difference is
noticeable, mechanical parts (except solenoids, sens ors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) display ed on CONSULT-III 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-III indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSUL T-III at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).

Diagnosis Procedure without CONSULT-III
INFOID:0000000005397252
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.

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

2. Perform "Diagnostic Procedure Without CONSULT-III" .
3. Turn ignition switch OFF. (The se lf-diagnostic results will be erased.)
