How to Activate the Tire Pressure Monitoring System on a 2005 GM Truck

The tire pressure monitoring system on a 2005 General Motors truck consists of four tire sensors, a radio frequency receiver, and a number of modules that work together including the BCM, PCM, and passenger door module, or PDM. The tire monitoring system is activated by default, but whenever the PDM is replaced the Tech 2 scan tool must be used to enable the tire pressure monitoring system. The Tech 2 is GMs factory scan tool, and it is also the only scan tool that can re-activate the TPM system.

Instructions

1

Turn the ignition ON and connect the Tech 2 to the vehicles diagnostic communications port.

2

Power on the Tech 2 and select Diagnostics from the main menu. Select 2005 for the model year.

3

Select LD Trk, MPV, Incomplete. Choose the make of your truck from the menu, then select the body type.

4

Select F2: Chassis, then select Equal to or Under 8600 GVW.

5

Choose Tire Pressure Monitor, then choose TPM Option Enable. Select the option to enable the TPM system from the TPM Option Enable screen. Press exit to move back to the TPM main menu.

6

Select the Tire Type/Pressure Selection menu and enter your tire and pressure information. This information is located on the door sticker inside the drivers door. Press exit to move back to the main menu once youve entered this information.

7

Select Learn Sensor Location from the TPM main menu. Follow the on-screen instructions to allow the PDM to learn the sensor locations. Press exit to move back to the main menu once you are finished. Power off the Tech 2 and disconnect it from the vehicle. Turn on the engine and confirm that the TPM system is activated and operates properly.
