Multi-function Transmission Range (TR) switch, checking - 5 Spd. Automatic Transmission 01V

Note:
^ Check the measuring value block for the TR-switch display group number 004 before checking the TR-switch.
^ Be sure that selector lever cable is properly adjusted.

Two different multi-function switches were used in production:

Note:
1. Multi-function switch with 8-pin connector
