Mark II System Diagnosis

MARK II NAVIGATION SYSTEM DIAGNOSIS
The reduction of Nav system components also reduces the scope of diagnosis. The Nav computer and Board monitor are the systems which must be considered for when diagnosing the total system.




The Mark II Navigation computer does not communicate with the DIS tester. Use the onboard diagnostic screens outlined on the previous pages for navigation system specific diagnosis.

Follow the fault symptom path of the DIS Diagnosis Program for detailed diagnostic procedures of the board monitor and LCD panel.
