TROUBLESHOOTING THE HMMWV - OD1616 - LESSON 2/TASK 1
this message
appears, he releases the TEST button and waits for the
offset value
to appear on the display.
The offset value should be
between -225
and +225.
Since the value received was well within
these limits,
SSG Boyce proceeds to the next step.
the TEST SELECT switches.
He then presses and releases the TEST
button. Since the message word GO appeared on the display, SSG Boyce
turns the rotary switch to the START position until the message word
OFF appears on the display.
SSG Boyce waits for the display to
change again.
A number should be displayed; however, the display
changes to E013.
This error message indicates that the battery or
batteries need to be-charged. Once they have been charged, the test
procedures are repeated. If E013 is displayed again, this indicates
that the battery or batteries need to be replaced.
They should be
replaced following the procedures in paragraph 4-56, page 4-92 of the
TM.
Had this not been the case, SSG Boyce would have proceeded to the
next step in the test procedures and measured the battery resistance.
For an M998, like the fictitious one we have been testing, the
battery resistance should be 13 milliohms.
After completing the necessary repairs, SSG Boyce reruns the Go Chain
tests to verify that the malfunction has been corrected and that no
additional malfunctions exist.

Conclusion
In this task, we covered STE/ICE. We covered what it is and how it
operates. We also covered how to use this piece of test equipment to
troubleshoot malfunctions occurring in the HMMWV.
