GAUGES

•Validate PIDs (Parameter Identiﬁ ers)

Accesses the factory system to determine which gauges can be supported. This is done

automatically when the module powers up. It is only required to be done manually if the

module has been re-ﬂ ashed.

•About Gauges

This screen will display a pop-up with information about the gauges.

•OBD2 Communication

Auto Disable (default)

The module will communicate with the vehicle’s OBD2 system unless it detects another

device. This may be a scan tool or aftermarket programmer connected to the vehicle.

Always Enabled

The module will communicate with the vehicle’s OBD2 system even when a scan tool

or aftermarket programmer is connected. However, some scan tools and aftermarket

programmers will not function when this option is enabled.

Disabled

The module will not communicate with the vehicle’s OBD2 system. This option applies when

using a scan tool or aftermarket programmer that does not allow multiple connections at

the same time.

Enabled on Demand

The module will only communicate with the vehicle’s OBD2 system when the vehicle info

or gauges screen is displayed. This is used in vehicles that issue a periodic vehicle health

report through a factory system such as Sync or OnStar. However, applying this setting may

cause the fuel economy calculations to be inaccurate.
