I open the scanner and connect to my truck (2002 Chevy Suburban 2500 w/8.1 and 4L85e) and as soon as it starts to communicate with the truck the radio (stock radio) resets the time to 1:00 and it will continue to reset and cycle the CD eject. I don't get the radio back until I write a program to the truck and have the scanner disconnected. Has anyone else had this issue?
not with hptuners but I have a 96 tahoe I tried one of the cheap China Bluetooth scanners on and it did that. wouldn't connect to the ecm but caused the radio to freak out. don't think it reset the time but the CD definitely cycled.
weird.
i had issue once with 2001 Vette. for unknown reason radio communication link on DLC burnt my HPT and had to send it for replacing it. from that time on any Chevy if i wan't t work with Chevy i do remove eighter pin on DLC connector or fuse if possible
best regards

On my 04 Vette it stops the clock operation as well as the radio. I usually just turn it off and cruise around with it off if logging.
I reset the clock when done. Did this with MPVI1 & 2 but most notably on the version 3.x and up software.

sounds like an obd port issue to me.Quote:

Has anybody got this issue resolved? I am going through it right now on my 99 vette.....
I haven?t played with it since my car is apart. I just reset the clock after working with it
This is common on gm 2500's. Several other manufactures of flashing devices say to pull the infotainment fuses before connecting to the obd2 port. Give that a try.
