Transmission Position Sensor/Switch: Testing and Inspection



5 Speed Automatic 01V

Multi-function Transmission Range (TR) switch, checking


NOTE:
- Check the measuring value block for the TR-switch display group number 004 before checking the TR-switch. Refer to "Scan Tool Testing/Measuring Value Blocks (Function 08)/Evaluating Measured Value Blocks -E17-" Testing and Inspection
- Be sure that selector lever cable is properly adjusted.


Two different multi-function switches were used in production:
1. Multi-function switch with 8 - pin connector checking starting.
2. Multi-function switch with 10 - pin connector checking starting.

Multi-Function Transmission Range (TR) Switch -F125- (8-Pin Connector), Testing

1. Function test







- Release spring catch securing 8-pin connector -2- to connector on wiring to multi-function TR switch.
- Unclip connector to multi-function TR switch from retainer or remove retainer together with connector from transmission to gain better access to the pins in the connector.







- Pin assignment for 8 - pin connector of Multi-function (TR) switch -F125-
- Use multi-meter VAG 1526A or Vehicle Diagnosis, Measuring and Information System VAS 5051.
