Emergency Mode In The Event Of A Fault

When a fault has arisen in the transmission (permanent fault) and is registered by the Transmission Control Module (TCM), a help program for dealing with the fault is activated. The Transmission Control Module (TCM) then performs certain actions to protect the transmission while maintaining as much driveability as possible. Minor faults do not activate any help programs. There are different programs depending on the type of fault.

• Emergency/limp-home mode
• Failsafe action (temporary action)

Failsafe action is activated upon first detection of the fault, if the fault disappears then the system returns to normal function. Emergency mode is activated with less serious faults and Limp-home mode is activated with the most serious faults. If the fault disappears (intermittent fault) then the control module returns to normal function as soon as the ignition is next switched on.

The warning lamp in the combined instrument panel comes on, and a text message is displayed in the text window in the combined instrument panel if emergency/limp-home mode has arisen. No text is displayed when the ignition is switched on until the fault has been detected.
