p Figure 6- T3 audio amplifier calibrations, GMSPS
For example, I recently had a 2017 Cadillac that would randomly
exhibit a loss of radio control head display, along with
the instrument cluster going dark, along with several low speed
(SWCAN) network DTCs. What I believe was happening was
there was a network communication problem during startup
on this vehicle. After checking pin fitments on every module,
and power supply voltage circuit integrity, I kept looking at the
modules on this bus and took a deeper look at the programming
version levels.
I found a software update applicable to the audio amplifier
with a note stating, " New software to update GMLAN vector
handler " (Figure 6). Here, I figured I was onto something, but I
really had no idea what this " CAN vector handler " was going to
do, but I figured I would go ahead and perform the update.
