2001 AUDI A8 01V Transmission Electrical Testing Workshop Manual

1) This test cannot be performed on vehicles with E-gas. The signal is transmitted from brake light switch or brake test switch
to Engine Control Module (ECM). The ECM then forwards the signal to the Transmission Control Module via the CAN-Bus. 2) Pin 28 at the control module is vacant for vehicles with 10-pin connector of multi-function switch -F125-.
