I have the Service Engine Soon Light On, Brake Light On, Anti Brake Light On, Trac Control Light On.

There is no code when a scanner is connected.

I have heard of disconnecting my battery and connecting the two terminals together. Another report was to replace instrument cluster.

Was told there is no communication to EBMC module or something like that, does anyone have an any ideas about this issue.

Can someone come up with a fix. This all happened about two weeks after the AC was replaced.

 

It would help if you posted what kind of car you have.
I would start looking for loose wiring that could have been knocked loose during the A/C fix.

 

The trouble I am having is with a 2000 Olds intrigue!

This issue occurred about a week after having the AC replaced.
I have had two different people try reading a code but the test unit does not provide any type of trouble codes.
