Transmission Position Sensor/Switch: Testing and Inspection

Mode Switch Test





1. Remove the screws securing the mode switch, then remove the switch.
2. Disconnect the connector from the switch.
3. Check the S mode switch for continuity between connector terminals No. 3 and No. 5.
There should be continuity while pressing the S mode switch, and no continuity when the switch released.
4. Check the D mode switch for continuity between connector terminals No. 1 and No. 5.
There should be continuity while pressing the D mode switch, and no continuity when the switch is released.
5. If either switch is faulty, replace it.
6. If the switch is OK, but switch failure occurred, check and repair the wire harness on the mode switch circuit.
