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 con-
troller 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).
