Diagnosis by CONSULT-II NOTICE 1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each solenoid). 2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Manual may differ slightly. This occurs because of the following reasons: I Actual shift schedule has more or less tolerance or allowance, I Shift schedule indicated in Service Manual refers to the point where shifts start. 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 displayed 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 RESULT TEST MODE Refer to AT-14.
