TROUBLESHOOTING -- CONTINUED
This test is now designated as STE--ICE--R (Reprogrammable). The R indicates its circuit boards can now
be reprogrammed at depot. There are no other changes to this test set. For testing purposes, STE--ICE and
STE--ICE--R are the same.
The Simplified Test Equipment for Internal Combustion Engines (Reprogrammable) (STE--ICE--R) set connects to
the M88A2 HRV Diagnostic Cable Assembly (DCA) located at the drivers station. The DCA reduces the mechan-
ics 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 the
M88A2 HRV, a vehicle identification number (VID) of 04 must be entered into the test set before a test number is
entered. 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.
STE--ICE--R provides measurements on voltage, resistance, pressure, temperature and speed to analyze the
condition of an engine system.
STE--ICE--R can also be used as a preventive maintenance tool, ohmmeter and ammeter. For these applications
refer to TM 9--4910--571--12&P.
Description and Use of STE--ICE--R Equipment

Throughout troubleshooting of the electrical system or electrical components, be certain vehicle MASTER
switch is OFF between every step unless otherwise directed. Remove all jewelry and metal objects when
working 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 the
harnesses involved. Refer to the electrical schematics (FP--1 through FP--22) when performing the troubleshooting
on the electrical system.
When troubleshooting any electrical system or component, exercise extreme care to prevent electrical shock.
