INTRODUCTION STE/ICE–R (SIMPLIFIED TEST EQUIPMENT FOR INTERNAL
COMBUSTION ENGINES-REPROGRAMMABLE) PROCEDURES—Continued
0107 00
TEST METHOD
The test method consists of a pre-test inspection and STE/ICE–R testing.
Pre-test Inspection
Before using STE/ICE–R to test the carriers, perform the following pre-test inspections:
a. FAN BELTS.
Check for proper tension. Replace if cracked of frayed.
b. OIL LEVEL.
Bring up to proper level if l ow.
c. FUEL LEVEL.
Check that the fuel tank has enough fuel for testing.
d. RADIATOR.
Bring up to proper level if l ow.
e. BATTERY.
Replace the battery if the case is cracked or the terminal posts are damaged. Clean
off all corrosion. Check that the battery connections to ground and starter motor are
in good condition, securely connected, and clean. Check the electrolyte level. See
TM 9-6140-200-14. If low, bring up to proper level with distilled water.
Vehicle Test Card (VTC)
Once familiar with STE/ICE–R testing procedures, the vehicle test card (located on (WP 0107 00)) 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. N ext, a table is provided which lists many
measurements that are useful in troubleshooting the carrier. The table includes the associated VTM test number, a ny 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 t o be performedfirst. 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.
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 Guild Troubleshooting.”
The rules to follow when using STE/ICE–R engine troubleshooting method are:
(1) Never enter in the middle of a procedure.
