to the ECM fuse that provides power to
the injectors (Figure 7).
Our goal was to monitor the voltage and
current ramping of the injectors while performing
a wiggle test on the harness. One
technician performed the wiggle test while
another technician focused on the oscilloscope.
No problems were found during
this test. We let the vehicle hot soak after a
long road test and the problem occurred as
soon as we restarted the vehicle.
As we continued the diagnosis, we could
confirm the hot soak would trigger the
problem every time (perfect, a bad PCM
it is!). We replaced the PCM and reflashed
it with the Autel Ultra's MaxiFlash VCMI
and GM's Service Programing System. We
did use a Matco MC9440 Battery maintainer
for our power supply for the vehicle's
stable voltage (Figure 8).
A quick side note, that battery maintainer
is getting on the older side and can
only handle 50A. It is recommended that

a 100A battery maintainer be used for
today's cars, so we will be upgrading very
soon. Vehicle was extensively road tested
and verified to be fixed!
Remember, our time is money so understanding
the systems you are working on
is critical to making an accurate and fast
diagnosis. Know your tools and how to
