Component Tests and General Diagnostics

Transmission Control Module

In the event of a failure of individual or several components or sensors, the Transmission Control Module (TCM) (J217) activates corresponding substitute functions. This ensures nondestructive operation of the transmission with the consequent effect on the function and quality of the shifts.

Three conditions can be distinguished which are recognized by the multitronic.





1. The trouble code is stored and a substitute program allows the vehicle to continue to be driven (with some limitations). The driver is not alerted to this condition, since it is not critical to safety nor for the transmission. The transmission range display in the instrument cluster indicates as normal the particular range that has been selected - arrow -. The driver may notice a difference in vehicle driveability and contact an authorized dealer.







2 The trouble code is stored and a substitute program allows the vehicle to continue to be driven (with some restrictions). The fully illuminated transmission range display in the instrument cluster shows the driver a simple malfunction - arrow -. This malfunction is barely noticeable to the driver, but the brightly lighted transmission range display is intended to indicate that he or she should consult an authorized dealer as soon as possible to avoid subsequent damage in the transmission.







3 A flashing transmission range indicator in the instrument cluster points to a serious malfunction in the transmission - arrow -. The condition is critical to safety or for the transmission.

CAUTION!
A flashing transmission range display indicator in the instrument cluster means the vehicle could come to an immediate stop or might not continue operation the next time the vehicle is stopped. This could mean that stopping at a traffic signal can cause traffic to be obstructed.

The flashing transmission range display is requesting the driver to stop his or her vehicle at the nearest possible location and to inform an Audi authorized dealer.

• In specific cases following a short wait, driving can be resumed by restarting the engine. In any case, the driver should immediately consult an Audi authorized dealer.

If the TCM fails, for example, due to a loss of the voltage feed, it will not be possible to continue driving.

CAUTION!
When the vehicle is towed, the transmission selector lever must be in the "N" position and it must not be towed more than 50 km and not above 50 km/h, otherwise the transmission will be destroyed.
