TROUBLESHOOTING PROCEDURES
Table 1 lists common malfunctions that you may encounter with your equipment along with the
troubleshooting procedure related to that malfunction. Refer to the list and locate the particular problem
you are experiencing. Once you have found the problem in the list, go to the specific troubleshooting
procedure detailed in WP 0009 00 related to that problem. Perform the tests, inspections, and corrective
actions in the order they appear in the troubleshooting procedure.
The fault codes listed in Table 1 refer to codes displayed visually via the System Fault advisory light and
heard audibly through the in-tent controller assembly. For example, if the System Fault advisory light
flashes 5 times accompanied by 5 audible tones, this indicates a Fault Code 5 which, by referring to
Table 1, indicates an “Glow Plug” problem. You would then refer directly to Item Number 9 in the
troubleshooting work package for detailed troubleshooting procedures on that subject.
This table cannot list all the malfunctions that may occur, all the tests and inspections needed to find the
fault, or all the corrective actions needed to correct the fault. If the equipment malfunction is not listed or
actions listed do not correct the fault, notify your supervisor and they will notify unit maintenance.
