INTRODUCTION
This work package contains operator level troubleshooting procedures for correcting unsatisfactory operation
and basic equipment malfunctions for the M915A1 equipped ABS. Operator troubleshooting will not include use
of the ABS diagnostic modes or use of a hand-held diagnostic tool.
Each troubleshooting procedure lists a fault symptom describing a specific problem. Under each symptom is a
list of possible malfunctions in the order of probability that may be the cause of the problem. Finally, each
malfunction is provided a corrective action followed by work package or TM reference, or instruction to notify
Field Maintenance to correct the problem.

NOTE
This TM cannot list all possible malfunctions that may occur. If the
symptom for a particular problem or malfunction is not listed in this
work package, notify your supervisor.
Isolate the component where the malfunction occurs by finding the symptom that most accurately describes
the problem.
Perform troubleshooting procedures in the order in which steps are listed.
Consider the possibility that the problem could be simple in origin and may require only minor adjustment:
use common sense.
If a problem cannot be corrected after performing all corrective actions listed for a given symptom, notify
your supervisor.
If the corrective action is not authorized at the operator level, operators should provide a brief written
description of the problem using Equipment inspection and Maintenance Worksheet, DA-Form 2404 or
