2000 Seville STS No Amp Data

Recommended Posts

I would like to introduce myself as being a newby my name is Ray.

I recently purchased a 2000 STS and it has few code issues.

U1000 class 2 communication malfunction

B2355 driver front vertical sensor malfunction (seat)

No AMP Data - when I unplug amp fuse (30A) and reinsert the radio will come on for about 3 seconds and then display clock only

All diagnostic info was from drivers info display

Any help would be greatly appreciated

ok. Try this, disconnect the battery, take the time to clean the connections really good. Make sure all fuses are installed and reconnect the battery. Post your results and codes if any.

Also welcome to a very useful forum. Please feel free to post pics.


Nice, clean, luxury= fine automobile

Thanks for the input, I replaced the amp with a spare one and that took care of the U1000 code and also No Amp Data ( there was evidence previous owner hooked up an aftermarket sub-woofer to the factory sub) Only code left is the B2355 seat code, which I will live with til I can find someone with a Tech2 to help diagnose.
