I have 2 malfunctions.1) "Battery visit workshop" is not going away even after changing both batteries and BCM .any ideas ? Anyone ?

2) brakes service- turns out I need new SBC unit. Can I put in a used one ?

When I had the fault "Battery visit workshop" it was the alternator that had failed.

The battery voltage should be about 12 volts with the engine not running and when you start the engine it should go to about 14.2 volts. If this is what you are getting then it would seem that the alternator is OK.

The car starts nicely even when being idle for many days. The " conveniences unavailable" warning goes away after few mins of starting and Ac starts to work just fine. But the red " battery, visit workshop" message persists !

Hmm, mine was cured with a replacement main battery. Maybe you have a current draw which is taking too much whilst the car is off. Do you use the car a lot or is it standing idle a lot?

Do an advanced search for SBC - you should find the most recent OP by RAJ55 which covers it...

It might be a good starting point for your battery issues, although I had similar problems I never got the red symbol only white. I reprogrammed the Rear Sam manually and the problem was solved.

What SBC issue are you having is it that you have reached the counter limit or has it been diagnosed as a pump issue?

1.SBC counter limit has been reached. What is the solution for that ? Replacement or reprogramming ? Can a used SBC be installed and programmed ?
2. What is " rear Sam " ? How do you program it manually ?
