Emergency Running (Mechanical/Hydraulic Limp-Home Mode)

Should slip be detected, due to a mechanical failure or loss of pressure, the transmission will either shift to, and hold 3 or shift to, and hold, the last gear which was known to be all right. This condition may be cleared by cycling the ignition OFF/ON following mechanical repair.

The operator will be made aware of certain faults by a warning message on the instrument cluster.

Data concerning OBDII related transmission failures is stored in the ECM for access via the J1962 socket.
