Susmic Controller (cont)
The controller incorporates four LED’s which indicate the condition of the transmission control system. The LED’s and their function are as follows:
POWER (Green) Monitors the external voltage (after the starter switch) when the engine is running. If the voltage is correct this LED will be permanently lit.
SYSTEM (Green) Monitors the controllers internal 5V DC supply. If the voltage is within limits this LED will be permanently lit.
MODE (Yellow) Software check. Normally flashes continuously at a rate of approximately one flash per second.
Status (Red) System error indicator This LED is normally not lit. If the controller detects a fault in the system the LED will flash. It will flash in a pattern determined by the nature of the fault. The pattern is based on a repeating sequence of four
flashes, which are either long ( _ ) or short ( . )(rather like Morse Code). The actual pattern of flashes indicates the nature of the fault. (See following page.) The LED error signals and their causes are described overleaf. Note that two or more LED’s may be indicating errors at the same time.
