Circuit/System Verification
WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
- Inflate all tires to the proper pressure and drive the vehicle over 40 km/h (25 MPH) for over 2 minutes. Refer to Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label .
- Using the J-46079
, activate each tire pressure sensor and record each sensors tire pressure reading. See Special Tools . Check the tire pressures with a known accurate hand held tire pressure gauge. Verify that the pressure readings from the special tool do not differ more than 27.6 kPa (4 psi) from the actual tire pressure readings.
- If not within the specified range, replace the suspect tire pressure sensor.
- Using a scan tool, enable the TPM learn mode. Use the J-46079
in simulate mode to learn 4 simulated sensor transmissions into the RCDLR. See Special Tools . Observe tire pressures in the scan tool data display. Verify the simulated tire pressures do not differ more than +/-27.6 kPa (4 psi) of the scan tool reading.
- If not within the specified range, replace the RCDLR.
- Using a scan tool, select instrument panel special functions Lamp Test. Command the instrument panel warning lamps OFF. Verify the tire pressure monitor indicator icon turns OFF.
- If the tire pressure monitor icon does not turn OFF, replace the IPC.
- Ignition ON, use the scan tool to setup the Tire Type/Pressure Selection in the RCDLR Module Setup menu. Refer to the Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label
. Verify the tire pressure monitor indicator icon turns OFF.
- If the tire pressure monitor icon does not turn OFF, replace the RCDLR.
