FIELD LEVEL MAINTENANCE
TROUBLESHOOTING INSTRUCTIONS INTRODUCTION
This chapter contains Field Level troubleshooting procedures to diagnose and correct the most common
malfunctions of the HEMTT THAAD Launcher System. Refer to (TM 9-2320-325-14&P) for M977 series vehicle
troubleshooting and THAAD Launcher IETM for MRP and missile launcher system troubleshooting.
Each troubleshooting procedure in this manual lists a malfunction, followed by tests or inspections, and the
corrective actions needed to correct the malfunction. This manual cannot list all malfunctions that may occur. Nor
can it list all test, inspections, and corrective actions needed to correct the malfunctions. If a malfunction is not
listed, or if listed corrective actions do not correct the malfunction, notify your Supervisor. See (WP 0019) for an
index of THAAD troubleshooting procedures.
Before beginning any troubleshooting procedure, read and understand the operating procedures listed in
Chapter 2 of this manual. Perform all applicable Preventive Maintenance Checks and Services (PMCS)
procedures for the M977 series vehicle (TM 9-2320-325-14&P) and THAAD Launcher System (WP 0050). Ensure
all system setup procedures are completed.
All steps in these troubleshooting procedures must be performed in the order listed, to ensure all system interlocks
are in the correct position for system operations. Listed below is an outline of the conditions required to operate the
HEMTT THAAD Launcher System. All troubleshooting procedures in this manual were written without the MRP
