Section II. TROUBLESHOOTING PROCEDURES
This section contains information on locating faults and causes of hydraulic malfunctions that may develop in
the M9 ACE. An alphabetical symptom index is provided.
Before you begin troubleshooting, ensure the defect is real. If possible, talk to the operator or mechanic that
reported the problem. Look for any other problems that could cause the system or component to malfunction, such as
a switch or lever in the wrong position. Refer to TM 5-2350-262-10 for correct operating procedures. Check fluid levels
as shown in TM 5-2350-262-10.
Many faults can be located by a good visual inspection. Look for leaks, loose or corroded connections, damaged
controls, and loose or damaged linkages.
When working on the hydraulic system, follow the general hydraulic system repair methods and refer to the
general hydraulic system troubleshooting procedures.
If you use the optional STE/ICE-R tests, use the STE/ICE-R Operator's Manual (TM 9-4910-571-12&P) for
reference before and during testing.
When trying to isolate a fault, review the past maintenance record on the affected vehicle. Although it doesn't
happen often, an incomplete or poorly performed maintenance task may lead to another problem.
USING THE TROUBLESHOOTING PROCEDURES
Find the symptom in the symptom index. Go to the page referenced for that symptom. All possible malfunctions
cannot be listed. If the specific malfunction is not listed in this section, refer to vehicle hydraulic schematic diagram for
additional information or reference data.
