Multi-function Transmission Range (TR)
switch, checking


Note:

Check the measuring value block for the TR-
switch display group number 004 page 01
-

before checking the TR-switch.

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 page 01

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.
