MARK I DIAGNOSIS AND TROUBLESHOOTING
There are three diagnostic programs for the On Board Monitor system with the Mk-1
Navigation Computer with video module.
Based on the customer complaint, one or more of these systems will need to be accessed
with the DIS Tester for diagnostic purposes.
The On Board Monitor system must be fully
functional before any visual displays, inputs
or programming can be carried out.
The Video Module must be fully functional
before any graphical displays can be
transmitted to the Monitor unit.
The Navigation Computer must be fully
functional before any programmed
destinations can be called up for display
and directions.
In all cases fault troubleshooting should begin with the Fault Symptom troubleshooting
paths provided by the DIS.
In the case of positioning errors or faults with the Navigation System, the DIS will request a
Sensor Test be performed prior to carrying out the diagnosis. This test procedure is
outlined in the calibration procedures.
