STE/ICE-R TROUBLESHOOTING INTRODUCTION

SIMPLIFIED TEST EQUIPMENT FOR INTERNAL COMBUSTION ENGINES REPROGRAMMABLE

(STE/ICE-R) TROUBLESHOOTING

a. General. This work package contains information and tests which may be used with STE/ICE-R to

locate malfunctions that may develop in the vehicle. The tests can be used during troubleshooting, PMCS, or

after replacing parts to isolate malfunctions, anticipate failures, and to ensure that proper repairs have been

made.

STE/ICE-R is used primarily with the vehicle electrical system. These tests cannot cover all possible

troubles which may occur. If a particular malfunction is not covered, refer to Electrical Troubleshooting,

WP 0011 00, and locate the troubleshooting procedure for the malfunction observed. To obtain the maximum

number of observed symptoms of the malfunction, question the operator.

b. STE/ICE-R Chain Index. Preventive Maintenance Checks and Services (WP 0022 00) contains a list

of various troubles which may occur during operation or inspection of the vehicle. When one of the

malfunctions listed occurs, the mechanic proceeds to the associated STE/ICE-R Chain Index.

c. Vehicle Test Meter (VTM) Troubleshooting. Vehicle Test Meter (VTM) troubleshooting procedures

can be found in Table 2, STE/ICE-R GO-Chain Test (WP 0016 00). For additional VTM troubleshooting, refer

to TM 9-4910-571-12&P, Simplified Test Equipment for Internal Combustion Engine.

d. STE/ICE-R Test and Setup Procedures. STE/ICE-R setup and internal checks must be performed

prior to testing. Specific setup procedures are listed in WP 0016 00, Table 1, Engine GO Index, Combined

Mode Chain, Test Number GO 1. Those test capabilities applicable to the ESP PMCS are listed in

WP 0017 00, Table 1, Engine NO-GO Index, Combined Mode Chain, and are included in WP 0017 00, Table 2,

STE/ICE-R NO-GO Chain Test. Test capabilities that may be applied to troubleshooting procedures are found

in WP 0016 00, Table 1, Engine GO Index, Combined Mode Chain.

e. STE/ICE-R Operation. For a description of the operation of STE/ICE-R, refer to TM 9-4910-571-12&P.

f. Vehicle Test Card (VTC). The VTC provides a quick, but limited reference for the operator when

performing STE/ICE-R tests. These cards list the test numbers and summarized instructions for diagnosing

and testing malfunctions on ESP vehicles.

g. Engine Chain Indexes. An index for ESP vehicles GO (WP 0016 00, Table 1) and NO-GO

(WP 0017 00, Table 1) chain tests precedes the tests listed.

Use VID entry 02 on test select switches.
