INTRODUCTION TO TROUBLESHOOTING
The Troubleshooting table lists common malfunctions found while operating or servicing the M548A1 and M548A3 and its
components. The troubleshooting table is divided into sections. Each section covers malfunctions common to the different
systems of the carrier (e.g., engine, transmission, and electrical, etc.).
The TROUBLESHOOTING TABLE has three divisions: MALFUNCTION, TEST OR INSPECTION, and CORRECTIVE
ACTION. The MALFUNCTIONS are numbered in sequence through the TROUBLESHOOTING TABLE. The
MALFUNCTION is what will bring you to the TROUBLESHOOTING TABLE.
TEST OR INSPECTION is a step you take to isolate the MALFUNCTION. Each TEST OR INSPECTION has a
CORRECTIVE ACTION. You should perform the TEST or INSPECTION and CORRECTIVE ACTION in the order listed.
The TROUBLESHOOTING TABLE for the M548A1 and M548A3 are listed in the symptom index (WP 0055 00).
The manual cannot list all possible malfunctions, nor all the tests or inspections and corrective actions. It is essential that you
record all faults on DA Form 2404 and report them to unit maintenance. If a malfunction is not listed, or is not corrected by
the listed corrective action, notify unit maintenance.
