I had one go bad on my 03 Impala and the horn would randomly start blasting and not turn off.In GM’s schematics and breakout diagrams for purchasing parts, what is the component they list as the BCM?
you connect a obd splitter to monitor via the 2nd Y portThere's different types of glade plug-ins that 'disable' V4 mode, by somehow tricking the ecm into thinking that one or more of the conditions that would prevent V4 mode happens to be in effect.
The plug-in that tricks the TCM into 5speed mode would cost some MpGs.
Not sure that's the most clever way of avoiding V4 mode, long-term.
What IS clever about those plug-ins, is that while the plug-in is plugged in,
How does one get any realtime ecm / tcm data? How does one look at what the plug-in is actually doing?
(petethepug, V4 mode is tuned out of the ENGINE control module, not the body control module, even if other modules can say something to the engine control module to prevent V4 mode.)
Years ago I blocked off the oil pressure relief in the oil pan, because the spring in it was failing. That increased the oil pressure and gave a more consistant pressure. The afm worked up until this issue. So, pretty sure this - along with 3000 oil and filter changes - contributed to the longevity.352k with AFM is better than a lot without AFM lol impressive!

I'll open it.I also run Quaker State full synthetic ultimate durability dexos 1 gen 3 - the one with the gold label.
It's the best on the market - but that's a serious pandora's box that I will leave closed ...
Im pretty sure my 2007 Tahoe LMG, vin0, engine cam broke (or cam chain broke?). Just shut off on highway, threw a code P0340. Removed cam sensor, stuck my finger in, rotated the engine by hand, and couldn't feel or see the reluctor wheel spinning. Verified by looking down the oil fill, rocker arms not moving.
So, with 352000 miles - completely stock - AFM operational until this - I am pulling the motor.
I plan on deleting the AFM, and installing the proper kit too do so - cam, block off plate, lifters, ecm delete, etc. etc.
Question I have - IF the engine I have cannot be used, what years can I use to replace the one in my 07 Tahoe?
Is there any 5.3s that do not have the AFM/DOD setup that will work?
The cam sensor is in the front cover, and the knock sensors are on the side of the block (easy accessed).
I am not looking for any type of performance upgrades (other than the afm delete) or larger displacement - just a job that can be easily done - because its getting cold and I'm doing this on the street lol.
Thanks for any help
