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.

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

Voltage measurement: switch multimeter to 20 V measuring range - Pin assignment for 8 - pin connector of multi-function (TR) switch -

- 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
