TM 9-2350-261-20-1 STE/ICE–R PROCED URE S (SIMPLIFIED TEST EQU IPMEN T F OR INTERNAL COMB USTION EN GINES REP ROGR AMMABLE) — Continued 0099 00 VEHICLE TEST CARD (VTC) Once familiar with STE/ICE–R testing procedures, the vehicle test card (located later in this work package) can be used as a quick reference. The front of the test card contains all of the information, in abbreviated format, that the user will need to perform common measurements on the carrier. The organization from the top of the card to the bottom represents a logical order of steps from powering up the VTM to completing a series of tests. The top of the card describes the power up sequence of STE/ICE–R for the carrier. Next, a table is provided which lists many measurements that are useful in troubleshooting the carrier. The table includes: the associated VTM test number, any required offset test limits, operating condition of the engine, special connections required, the expected limits for pass or fail, and the units of measurement. Also included on the front of the card are hook-up diagrams. The organization of the table allows measurements with the carrier engine turned off to be performed first. These measurements will ensure that the starting system of the carrier is in working order before proceeding. The order of the other measurements is as follow: •Measurements with the engine running but not warm. •Measurements requiring the engine to be warm and running. •Measurements requiring the engine to be warm and not running. •Miscellaneous measurements. The back of the VTC contains the hookups for measurements used to troubleshoot carrier components. Measurements that require special hookups are also included on this side of the VTC. To start the test message, first perform the pre-test inspection and then the charging system operational check (WP 0020 00). STE/ICE–R ENGINE TROUBLESHOOTING METHOD When a malfunction in the engine is recognized by the mechanic, the “flip cards to Troubleshooting” will provide a reference to a specific procedure to isolate the cause of the malfunction. To start the STE/ICE–R engine troubleshooting method, do the following: a. Perform Hook Up. First, perform HOOK UP to set up STE/ICE–R and check to see if it is in working order. b. Perform Procedure. Now that STE/ICE–R is hooked up properly and checks out, perform the procedure cited in the “Quick Guide to Troubleshooting.” The rules to follow when using STE/ICE–R engine troubleshooting method are: (1) Never enter in the middle of a procedure. (2) Follow each instruction in a procedure. Do not skip any instructions or procedures. (3) After correcting a problem with a procedure, test run the component, engine, or power plant to ensure the problem does not still exist. 0099 00-10
