Below are the GM Specific XGauge codes. They are broken down between the two ECU protocols that GM used, so you’ll want to program these XGauges based on what protocol your GM vehicle uses. All 2003 and older GM vehicles will use the VPW protocol. All GM vehicles from 2004 to 2007 may use the VPW or CANSF protocol. All 2008 and newer GM vehicles will use the CANSF protocol.
You can determine what protocol your vehicle uses by pressing MORE > MORE > MODE on the ScanGauge while it’s connected to the vehicle.
Some sensors may not be reported by the vehicle. If you try all available XGauges for a certain sensor and it doesn’t report any data then the sensor is most likely not supported by the vehicle.
Note: Sometimes the value 01 needs to be added to the end of a TXD to get the XGauge to work. This is why there is a (01) at the end of each of these XGauge’s TXD line.
