The section contains information and tests which may be used with STE/ICE to locate malfunctions that may develop in vehicle. 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. NOTE See tables 2-8 and 2-9 for a listing of STE/ICE tests and their related page numbers. b. STE/ICE is used primarily with the vehicle electrical system. These tests cannot cover all possible malfunctions which may occur. If a particular malfunction is not covered, refer to Troubleshooting Index (chapter 2) and locate troubleshooting procedure for malfunction observed. To obtain maximum number of observed symptoms of the malfunction, question the operator. 2-17.

VEHICLE TEST METER (VTM) TROUBLESHOOTING The vehicle meter (VTM) troubleshooting procedures can be found in STE/ICE Go-Chain Tests (table 2-10). Additional VTM troubleshooting can be found in TM 9-4910-571-12&P, Simplified Test Equipment for Internal Combustion Engines. 2-19. STE/lCE TESTS AND SETUP PROCEDURES a. STE/ICE Tests. The STE/ICE testing capabilities that may be applied to the M44A2 PMCS are listed in table 2-9 and are included in table 2-11. Test capabilities that may be applied to troubleshooting are specified in table 2-8. b. STE/ICE Setup Procedure. STE/ICE setup and internal checks (test no. G01, table 2-10) must be performed prior to performing tests. 2-20. STE/lCE DESCRIPTION AND OPERATION a. General.
