After all and it seems like a ground issue, put a jumping cable from the nagetive to the engine block and then try the chassis, it’ll work, I had a 08 suburban with same issues till it stopped cranking and it was a bad grounding somewhere and I put extra new grounds in different spots and even works better then it ever has
Have a 2010 with intermittent no crank no start have to pull ecm and cables and eeset electronics for 20 mins to start. Also gauges go crazy and drip and stabilitrak and abs come on until it kicks back in. Pull your "info" fuse in your driver fuse cluster. It cuts power to the bs onstar vcim which is causing interference on the high speed lan or can whatever i dont have a scanner. Anyways youll lose remote start which is what started acting up for me and doing . I got no comm to ecm bcm tccm everything. 3 months thru winter everyday having to pull cables and discharge it pissed me off it being onstar module i would never use
Ive been battling this for 6 months . I changed the ECM, bcm, terminal resister , negative battery cable, battery and the codes that always come up is loss communication with ecm and bcm
I think u done everything right but you have check to clean and scrap your grounds clean all of em bro or added new ones if you have to so you can have a shortage
Yo I need help my 2009 Tahoe has this issue it will turn over and drive but it also starts acting crazy like the stabilizer traction control issue will pop up i don’t have the crank problem it cranks and drives until the same thing happens again should I just change the module or what to do next

Try pulling your info fuse in drivers fuses. It cuts off the module Vcim onstar bs. Same no crank no start acting like a bcm/ecm on 2010 tahoe and this fixed it

Theft module and the pass 3 key
@@Handymandan215 I can drive it but I get ecm and bcm communication codes randomly and dash acts up
Did you guys get it fixed if not let me know
@@Edi-01 I’m still battling it
Been having the same issue on my 09 avalanche..ended up being the transfer case control module
You have an answer for the same problem on a 95 Chevy
Jawn? U from Philly?
😂😂😂😂 u already know 🗣💯
I think u done everything right but you have check to clean and scrap your grounds clean all of em bro or added new ones if you have to so you can have a shortage
It Was a new ECM and key
Hey man i have a mazda 3 2010 and i get that code and i get a pcm relay code thats bad by any chance can it be the relay ?
It can but usually if the code does go away it’s the PCM
Has anyone had the issue where the security light doesn’t come on after replacing the ECM?
What would cause this?
check 2amp fuse or the immobilizer switch not the ignition
@@Handymandan215 fuses for the ECM look to be fine. How do I check the immobilizer switch?
Hey have you ran into the problem of the anti theft light will not go out even after resetting?? Cuz that's where I'm at right now
new 🗝 🗝 key

@@dubs3238 yup sure did , freaking key needs to be programmed to the anti theft

Did you find out what it is
ECM or THEFT MODULE ,
Yes changed out the active suspension control module you have to get it program
Check the fuse box next too the BcM too the wires can be shorted or pulled
I have u1255 code on my k1500 1998 Idk what it is
No communication between a computer try unpluging the radio , bcm , check fuses , if anything time for a new ECM/PCM
Yo bro i get hard shifts and a slight clutter sound sometimes.. a shop said it showed pcm ecm communication is lost. Any thoughts?
dont driver over puddles theres a computer under the car will cause these code if anythj g its time for a new ECM

Check the mega fuses on the battery ..... Only change the Ecm when the u0100 POPS UP and doesn't start
Clean all your grounds bro or added new one if you have to
Did you get it fixed if not let know I have 07 Cadillac Escalade v8 had different problems but similar I can send you the list what I did bro
