You must have a code reader that is CAN enabled. CTSs as early as '04 require a CAN enabled reader. the 06 cts uses a CAN OBD-II CODE READER/EOBD SCANNER. When buying the scan or code reader for your vehicle, make sure it supports the Controller Area Network (CAN) protocol. CALL THE DEALER OR AUTO-ZONE MAY BE ABLE TO TELL YOU THE PROPER NAMED SCANNER TO USE. GOOD-DAY !

What does the b2aaa code mea for a 2009 chrysler sebring

This is not a valid code. You will find lots of hits online where people are reporting this code. It seems that the consumer grade scanning tools are not able to read the code correctly. I recommend taking it into the dealer and have them read the code.

Whats mean the code B2AAA for 2009 Mini cooper s Thansk

it means this P0420, make appointment for service, should come out like this code but if you out of service do this remove BCM (Body control module), PCM, ECM tcm FUSEs, waited 30 mins, the reconnect them and put battery back on, or if you don't want to do that take the battery off, then go inside the car and turn the ignition on and the lights and anything ells you can turn on. they won't work but they will drain the voltage stored in them, leave like this for 15-40 min and then reconnect the battery should be back to normal. but turn every thing off again before putting the battery back on.

My doughter just bought a 2005 cobalt, when we got home the check engine light came on. " used car..go figure." 2 codes 1.) B2AAA 2.) P0171 any help on how to fix these would be appreciated. ...

Im not sure what the b2aaa is but the p0171 is bank one ( line of cylinder's that has #1 cylinder in it) is lean. This can just be a bad oxygen sensor.
I need to know more. Is the idle smooth? Is the idle at a good speed? (motor not reeving or going to slow)
