TM 9--2350--292--20--10006 00--2TROUBLESHOOTING -- CONTINUED0006 00STE--ICE--R TROUBLESHOOTINGNOTEThis test is now designated as STE--ICE--R (Reprogrammable). The “R” indicates its circuit boards can nowbe reprogrammed at depot. There are no other changes to this test set. For testing purposes, STE--ICE andSTE--ICE--R are the same.IntroductionThe Simplified Test Equipment for Internal Combustion Engines (Reprogrammable) (STE--ICE--R) set connects tothe M88A2 HRV Diagnostic Cable Assembly (DCA) located at the driver’s station. The DCA reduces the mechan-ic’s need to install test transducers and leads to perform engine and engine component diagnostic tests. To suc-cessfully complete a STE--ICE--R test refer to TM 9--4910--571--12&P. To accurately diagnose a malfunction of theM88A2 HRV, a vehicle identification number (VID) of 04 must be entered into the test set before a test number isentered. Be sure to refer to the “Quick Guide to Troubleshooting (Symptom/Malfunction) Index” to locate the ap-propriate troubleshooting tree to isolate the cause of malfunction.GeneralSTE--ICE--R provides measurements on voltage, resistance, pressure, temperature and speed to analyze thecondition of an engine system.STE--ICE--R can also be used as a preventive maintenance tool, ohmmeter and ammeter. For these applicationsrefer to TM 9--4910--571--12&P.Description and Use of STE--ICE--R EquipmentFor a complete description of the STE--ICE--R set, all associated equipment and their uses, refer toTM 9--4910--571--12&P.ELECTRICAL TROUBLESHOOTINGWARNINGThroughout troubleshooting of the electrical system or electrical components, be certain vehicle MASTERswitch is OFF between every step unless otherwise directed. Remove all jewelry and metal objects whenworking on the electrical system to prevent injury due to electrical shock.Electrical troubleshooting in this chapter provides schematic diagrams and pictorial diagrams to give insight to theharnesses involved. Refer to the electrical schematics (FP--1 through FP--22) when performing the troubleshootingon the electrical system.When troubleshooting any electrical system or component, exercise extreme care to prevent electrical shock.
