The troubleshooting LEDs are located on the receiver board or accessible on the outside. Use the
following table to identify faults and corrective action.
In order to reach the internal signaling, the receiver must be accessible, connected and the screws
located on the receiver lid must be unscrewed using the proper screw driver whenever the LEDs are not
externally visible.
The LEDs on the receiver board are POWER, STATUS, DIAG1, DIAG2, ORDER, RELAY, CANERR and CANRUN
in that order.
