HOW TO ERASE SELF-DIAGNOSTIC RESULTS (WITH CONSULT-II)
1. If the ignition switch stays “ON” after repair work, be sure to turn
ignition switch “OFF” once. Wait for at least 3 seconds and then
turn it “ON” again.
2. Turn CONSULT-II “ON”, and touch “A/T”.

TROUBLE DIAGNOSES FOR SYMPTOMS
3.CHECK OVERDRIVE CONTROL SWITCH CIRCUIT (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out “OVERDRIVE SWITCH”.
Check the signal of the overdrive control switch is indicated properly.
(Overdrive control switch “ON” displayed on CONSULT-II means
overdrive “OFF”.)
