I have a 2000 Pontiac Bonneville SSEi. I can not scan my ABS/Traction/ESC modules, however I can scan almost all other modules in the car. I can scan Powertrain/Transmission, BCM, EVO/Theft Deterrent/Passlock. Drivers Door, Cluster, Drivers Seat, SIR, Radio/Navigation, Onstar and VCI. I have set the timing all the way up to FF, and this did not help. Hope someone can help me pull the data from the modules I really need to see, as I am having definitive errors in it. Thank you
Please, can you send me the debug log. Enable it under preference, connect to ABS module few times, exit app and send the log to Email
If the app is requesting data correctly or you have verified no communication with manufacturer scantool, then you may have a bad fuse, no power supply, or bad module. Good place to start is Technical Service Bulletin or there might be a recall on the ABS unit.
I sent the debug log. I attempted to connect to the abs, esc and traction module options in the log along with a correct scan and a generic obd ii connection. I know communication is good, a nearby mechanic and I have been troubleshooting ongoing issues with my wheel speed sensors, and with their snap on scantool, the abs/traction module reads fine. There is definitely communication possible with it.
