Hi guys I'm new to this got a gtc v8 tt the car had no batteries in wen it got delivered fitted new batteries still no start checked the dtc no major ones to point you in the direction. Then noticed there was no communication with some off the modules
Abs module
Esp
Tcm
Battery management
Possibly more can't remember
Sent abs pump and module off for testing came back as fine checked all wiring to abs there fine
Also can't do a battery adaptation

Any ideas guys

 

That battery management module fault sound like the culprit to me.

 

I'm going to work on the car today will try getting update for the dtc s

 

Hello @V8 Choppa ,
Please give a little history of the vehicle, in what condition is it, any body damage, or water damage, as it has 14 faults for the KESSY alone, do you have more than one keyfob, does the instrument cluster power up at all, is there any immobilizer message on the driver's information screen, have you checked every fuse, even the mega fuses, have you tried the key in the ignition vs. push button start ?

when I got the car I had to put the radiator pack back on it had been stood for 12 months there is no water in the car the Kesey unit is in the rear quarter I believe I put new batteries on went to start it all the lights come on on the screen it say low battery start engine when I press the brake and start button the Ignition switch clicks off and the power all shuts off. When I connect up a computer there in no communication to some of the modules I can carry out the battery adaptation. I’ve tried with a Ross tech and a autel

 

The car was vandalized before I got it there may on been light body damage to the front the air bags have not gone off here is some more dtc from today

 

Hi it turned out there was a after market tracker with immobilizer removed that and it started it's now in low voltage mode on the dash board any recommendations
Thanks

 

you mean low voltage / battery msg on the dash? white text or yellow text? depending on color it is battery in the car or battery in the fob

 

Yh that message think it was white. I did change the battery in the fob recently. Also the is no communication with the abs esp and air bags

 

My understanding from having a similar issue is the the LOW BATTERY message in white is for the car battery, in red is for the key fob.
