CORRECTIVE ACTION - Continued
MALFUNCTION
Wiring Between Connectors J4 and P2 is Faulty (Model B Only).
CORRECTIVE ACTION
CAUTION
Electrical power must be shut OFF from circuit before continuity can be checked.
Failure to comply with this caution may result in damage to test equipment or
electrical system.
NOTE
Digital controller and cab control box are not repairable, therefore, it is necessary
to test digital controller and cab interface wiring harnesses, switches, solenoids,
and other components to identify possible faults other than digital controller and
digital cab controller.
