FAULT RECOVERY

When a fault is detected by the speed controller, the speed controller will attempt to recover from the fault and resume
normal operation. In the case of an intermittent problem such as a loose wiring connection, the controller may be able
to recover and operate normally for a while, but the problem should be repaired before placing the vehicle in service.
Depending on the type of fault, the controller will attempt to recover immediately after the condition clears or after the
accelerator pedal has been cycled (released and pressed again).
