2.2. Switch OFF the ignition.
3. 3. Wait 10 seconds.
4. 4. Start the engine.
5. 5. Select R (reverse will be selected).
6. 6. Select D ( 2 will be selected).
The limp-home mode will be retained until the fault is remedied or the fault code has been erased. Intermittent faults may
be cleared by cycling the ignition OFF/ON. In certain cases the component may need to be operated before the fault code is
cleared eg. a shift solenoid.
Emergency Running (mechanica l/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 alright. 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 th e instrument cluster.
Data concerning OBDII related transmission failures is stored in the ECM for access via the J1962 socket.
Safety Functions
These functions are designed to safeguard against inappropriate actions by the operator as well as system malfunctions.
The electrical and diagnostic system has been designed such that system integrity is protected at all times, the safety
concept being based on th e following three points.
1. 1. The hydraulic system has 'fail-safe' characteristics regardin g its electrical operation, such that should the power
supply be lost to the electro-hydraulic actuators the transmission will initiate a limp-home mode.
2. 2. Recognition of critical shift operation by monitoring the last element in the signal path, ie the solenoid valve, and
checking by means of redundant me asured variables relative to engine, transmission and road speeds.
3. 3. Each time the vehicle is started there is a check on the entire safety hardware and the associated program parts
and signal paths. A malfunction in this part of the system, or triggering of the safety circuit, is communicated to
the operator by a warning messag e on the instrument cluster.
CAUTION: Do not engage R or P with the vehicle in motion.
Should R be engaged with the vehicle in forward motion, the transmission will default to neutral until either the vehicle
speed decreases to 4 mph or D is selected.
Towing
The vehicle may be towed provided that:
Selector in position N Speed < 50 kph Distance < 50 km
