Service & Maintenance

Troubleshooting

Diagnostics

In the event there is a problem with the AutoShift, there are three primary 
tasks the driver should perform:

1.

Note the driving condition under which the problem occurred.

2.

Note the condition of the AutoShift under which the problem 
occurred (i.e. operation mode (Drive, MANUAL, LOW), current gear, 
engine speed, etc).

3.

Reset the system.

Transmission Reset Procedure

In some cases, proper transmission operation can be restored by “resetting” 
the transmission Electronic Control Unit (ECU). Use the following procedure 
to reset the ECU:

1.

When it is safe to do so, stop the vehicle.

2.

Place the transmission shift lever in Neutral and turn the ignition key 
to the “off” position.

3.

Wait at least 2 minutes.

4.

Restart the engine.

5.

If the problem continues, contact a service facility to have the vehicle 
and transmission system evaluated.
