Inspection steps

1. Connect the SSM4 to the DLC3.
2. Turn the ignition switch to ON.
3. Use SSM4 to display the [Data monitor] screen according to the screen display and check the computer data recorded when the transmission shift switch of the steering wheel ASSY is operated to +/-.

NG: Go to Step  2.

OK: Go to next step

Inspection for problems that do not normally occur (Refer to MALFUNCTION SYMPTOMS AND DTC CHECK )

1. Disconnect the connector A19 of the transmission control computer ASSY.
2. Check the resistance of the terminals. (Refer to ECM TERMINAL ARRANGEMENT  for terminal arrangement of transmission control computer ASSY)
