Activation 

1. NOTE: The tire pressure sensors will go into a "sleep mode" when a vehicle is stationary to conserve battery power. The sensors transmit information infrequently while in sleep mode. It is sometimes necessary to wake them up so they will transmit the latest tire pressure information.
   NOTE: The tire pressure data in the BCM can be cleared when the module performs a reset. When this occurs, the air pressure DIDs will be reset to the factory default of 1033 kPa (149.96 psi) and the cluster will display dashes. Drive your vehicle for at least 2 minutes over 32 km/h (20 mph) or until the tire pressures are displayed. Alternatively follow the procedure below:
   NOTE: Position the vehicle one meter away from other vehicles to prevent interference from other vehicle tire pressure sensors.

   Turn the ignition switch to the ON position.

2. Position the special tool against the Left Front (LF) tire sidewall at the tire valve stem.Use Special Service Tool: 204-D081A (204-D081) Tire Pressure Monitor (TPMS).
3. NOTE: The special service tool should provide feedback in the form of a beep sound for each successful response from a tire pressure sensor. This feedback confirms that the tire sensor has responded, but doesn't provide confirmation that the vehicle receiver module has heard the response.
   NOTE: If the receiver module has not heard the sensor response, move the vehicle to rotate the wheels at least one-fourth of a turn and attempt to activate the sensor again. If the sensor is still not heard, attempt to activate again with the vehicle doors open.

   Press the test button on the special tool to activate the sensor. Use Special Service Tool: 204-D081A (204-D081) Tire Pressure Monitor (TPMS).

4. Repeat Steps 2 and 3 for the remaining tires. The normal sequence is Left front (as above) followed by Front Right, Rear Right and Rear Left.
5. If a tire pressure sensor does not respond to the service tool when positioned against the tire sidewall at the vavle stem, repeat the test with the tool antenna lightly resting on the valve cap. If after 3 attempts, one or more sensors does not respond or has a low battery, diagnose TPMS and replace as necessary.
   NOTE: The Tire Pressure Monitoring System (TPMS) sensor cannot be installed without disassembly of the wheel and tire
