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 the following three points.

1. The hydraulic system has "fail-safe" characteristics regarding 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. Recognition of critical shift operation by monitoring the last element in the signal path, ie the solenoid valve, and checking by means of redundant measured variables relative to engine, transmission and road speeds.
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 message on the instrument cluster.

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.
