After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT

1. Turn ignition switch “ON”. (Do not start engine.)

2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT.

3. Start engine.

4. Drive vehicle and maintain the following conditions for at least 2 consecutive seconds.

ACCELE POSI: More than 1.0/8

5. If DTC is detected, go to 

TM-51, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT”.

Diagnosis Procedure

INFOID:0000000007357130
