What to do if Simrad AP16 Autopilot System displays 'Memory failure ACXX'?
- JJanet VasquezSep 4, 2025
If your Simrad Autopilot System displays 'Memory failure ACXX', it means there's a wrong checksum on memory parameters or variables, and the Autopilot Computer will use default values. To resolve this: 1. Perform a "Master reset". 2. Switch the system off and on again. 3. If the alarm repeats, replace the Autopilot Computer PCB.
