2002 Chevrolet Trailblazer Q&A
2002 Chevrolet Trailblazer Question: What component is faulty if I get a b1000 DTC and no other code?
I have a 2002 Trailblazer LTZ with the airbag light and the phrase “Service Airbag System” scrolling across the dash in the info area. The Code reader shows only one code, and it’s B1000 which is ECU malfunction 2, according to my code reader. If you try and erase the code it says it is successful, but upon re-link it comes back. I already had myairbags.com reprogram the airbag module and get the same B1000 code. If I unplug any other sensors to the system then I get a code error for each of them. They disappear when the sensors are reconnected. I have no idea which component is causing the error. The Electronic Control module is communicating with the airbag module just fine. Is the Electronic Control module faulty? That is the module with three connectors located on the engine. - slycaulfey
i would say its safe to say the ecu is at fault, yes this module is located under the hood with three large connetors. - holston2008
