Multi-Function Transmission Range (TR) Switch, Checking



MULTI-FUNCTION TRANSMISSION RANGE (TR) SWITCH, CHECKING

Note:
- Check the measuring value block for the TR-switch display group number 004.
- 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.
2. Multi-function switch with 10-pin connector.

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 multifunction 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.
















Note: If function check was OK, check voltage supply to Multi-function TR switch -F125-.

2. Multi-function Transmission Range (TR) switch -F125- (8-pin connector), testing






- Release spring catch securing 8-pin connector -2- to connector on wiring to Multifunction TR switch.

- Check at connector with spring clips (cavities) to Transmission Control Module (TCM).






- Pin assignment for 8 - pin connector of multi-function (TR) switch -F125- (to TCM).

- Use multi-meter VAG 1526A or Vehicle Diagnosis, Measuring and Information System VAS 5051.

Voltage measurement: switch multimeter to 20 V measuring range






- If the specified value is not read, check fuses and wiring connectors according to wiring diagram and make necessary repairs.

Note: If the check results and the voltage supply to the Multi-function TR switch were OK, check wiring connections from Transmission Control Module (TCM) -J217- to Multi-function Transmission Range (TR) switch.

3. Wiring from Transmission Control Module (TCM) -J217- to Multi-function Transmission Range (TR) switch -F125- (8-pin connector), checking.






- Switch off ignition.

- Disconnect connector from TCM -J217-, located in front of right seat under the cover in the footwell.

- Connect test box VAG 1598/20 to harness connector.






- Connect both 8-pin connectors -2- to multi-function switch -F125- as shown in the illustration.

- Use multi-meter VAG 1526A or Vehicle Diagnosis, Measuring and Information System VAS 5051.











4. Wiring from Transmission Control Module (TCM) -J217- to Multi-function Transmission Range (TR) switch -F125- (8-pin connector), checking

- Switch ignition off.






- Release spring catch securing 8-pin connector -2- to connector on wiring to multi-function TR switch.






- Pin assignment on 8-pin connector of multi-function switch -F125- (cavities toward TCM).

- Check between 8-pin connector with spring clip closure (cavities) and test box VAG 1598/20 at connector of TCM.

- Use multi-meter VAG 1526A or Vehicle Diagnosis, Measuring and Information System VAS 5051

MULTI-FUNCTION TRANSMISSION RANGE (TR) SWITCH (10-PIN CONNECTOR), TESTING

1. Function Test






- Release spring catch securing 10-pin connector -2- to connector of 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 10 - pin connector of multi-function (TR) switch -F125-.

- Use multi-meter VAG 1526A or Vehicle Diagnosis, Measuring and Information System VAS 5051.
















- If function test is OK, check voltage supply to Multi-function TR switch -F125-.

2. Voltage supply for Multi-function TR switch (10-pin connector), testing






- Release spring catch securing 10-pin connector -2- to connector to multi-function TR switch.

- Check at connector with spring clips (cavities) to Transmission Control Module (TCM).






- Pin assignment for 10 - pin connector of multi-function (TR) switch -F125- (cavities to TCM).

- Use multi-meter VAG 1526A or Vehicle Diagnosis, Measuring and Information System VAS 5051.

Voltage measurement: switch multimeter to 20 V measuring range






- If the specified value is not read, check fuses and wiring connectors according to wiring diagram and make necessary repairs.

Note: If the check results and the voltage supply to the multi-function TR switch were OK, check wiring connections from Transmission Control Module (TCM) -J217- to Multifunction Transmission Range (TR) switch -F125-.

3. Wiring from Transmission Control Module (TCM) -J217- to Multi-function Transmission Range (TR) switch -F125- (10-pin connector), checking






- Switch off ignition.

- Disconnect connector from TCM -J217-, located in front of right seat under the cover in the footwell.

- Connect test box VAG 1598/20 to harness connector.






- Connect both 10 - pin connectors -2- to multi-function switch -F125- as shown in the illustration.

- Use multi-meter VAG 1526A or Vehicle Diagnosis, Measuring and Information System VAS 5051.





















4. Wiring from Transmission Control Module (TCM) -J217- to Multi-function Transmission Range (TR) switch -F125- (10-pin connector), checking

- Switch off ignition.






- Disconnect 10 - pin connector -2- to TR switch -F125-.






- Pin assignment at 10 - pin connectors of multi-function switch -F125- (cavities point to TCM).

Check between 10-pin connector (cavities) with test box VAG 1526A at connector of TCM.

- Use multi-meter VAG 1526A or Vehicle Diagnosis, Measuring and Information System VAS 5051.
