GM Extended Data Specifics

GM Extended Data Specifics

Our enhanced GM interface supports hundreds of sensors selected from the Powertrain, ABS, and Transmission systems. Support included for all GM family vehicles (Chevy, Buick, Pontiac, Olds, Cadillac, Saturn, etc) using the VPW interface including 4, 6, and 8 cylinder; Gas and Diesel (including Duramax).(Please note that many GM vehicles use the ALDL bus on pin 9 for ABS and AirBag Support. If your vehicle has pin 9 connected the scan tool may not be able to read ABS and/or AirBag Codes)
