SCOPE

This portion of the work package contains information on locating faults and causes of hydraulic malfunctions

based on specific symptoms that may develop in the M9 ACE that incorporates the HDC System.

GENERAL

Before you begin troubleshooting, ensure the defect is real. If possible, talk to the operator or mechanic that re-

ported 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 gener-

al 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 ref-

erence 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.
