ECU DIAGNOSIS INFORMATION

Reference Value
INFOID:0000000009267864
VALUES ON DIAGNOSIS TOOL
• The CONSULT 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 display. If the difference is notice-
able, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical parts in
accordance with the specified diagnostic procedures.
• Shift schedule (that implies gear position) on CONSULT may slightly differ from that described in Service
Manual. This occurs for the following reasons:
- Actual shift schedule has more or less tolerance or allowance
- Shift schedule in Service Manual refers to the point where shifting starts
- Gear position on CONSULT indicates the point where shifting completes
• Display of solenoid valves on CONSULT changes at the start of shifting, while gear position is displayed
upon completion of shifting (which is computed by TCM).
NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
