ASIC MPC DIAGNOSTICS CODES
The Amigo controller has a built-in diagnostic feature that will cause the
diagnostic LED lights (Figure 10) to flash a numeric code, indicating service
issues to aid in diagnosis. When indicating a service problem, the diagnostic
lights will flash, hesitate for a moment, and then flash again. Follow the code
listings below to determine the problem. Solutions should be attempted in the
order they are written. If the code indicates a service problem, contact your local
service representative or call the Amigo service department at (800) 248-9131 or
(989) 777-0910 for instructions to verify and correct the problem.
