dures classified by image failures.”

• If any image failure has occurred, first make the initial checks; then proceed to the corre-

sponding image failure troubleshooting procedure.

4-2.

Initial Checks

• Determine if the failure is attributable to a basic cause or causes.

• Determine if the failure is attributable to an input system (IR) or output system (engine) 

fault.
