data link failure on 03 Silvarado

I am not able to get a response with my code reader (works ok in other vehicles) when I plug into the data link on my 2003 Chevy pickup. Nada - acts like the code reader is broken. Any ideas? Thanks.

check the fuse to the cig lighter that part runs on the same thing as the code reader or so i have been told by someone else... i also had this problem on a cilvarado and ended up takeing it to my buddie who is a mechanic at firestone and he hooked up his modus and it worked and read fine... and when i took it to autozone they said they couldnt read the codes just like your saying.... hope this helps just telling you my experience, what the truck doing?

i think he means that the fuse for the cig lighter is on the same circuit as something on the DL connector wiring

in which is a common practice on the later model vehicles, sharing fuses for different circuits.

so i would check all fuses first before going to the stealership


id like to know the outcome to this for personal knowledge purposes.

i have a scanner for drivetrains and another for ABS and i do this stuff often here.,



thanks and good luck!

Like others have stated check the fuses first and then the grounds. A poor ground or a faulty ignition switch will also cause this type of problem. Hope this helps.

That's correct - the cigarette lighter and data link seem to be on the same circuit. Turns out that the instrument panel/cluster (IC) will be replaced under a recall warranty and that should take care of it. The data link/cig lighter circuit failure were the first symptoms of the bad IC. The speedometer became erratic overnight and that is when I took it to the stealership. The truck is under 70K miles so no charge on the new IC. They will have the unit next week and I will post how it all turned out. The dealership was fast and friendly - I have no complaints. They still want too much for a new rig though!
