Circuit/System Verification
WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
- Using the J-46079
, activate each tire pressure sensor and record each sensors transmission data and physical location. Verify J-46079
displays the 8-digit ID number, accurate tire pressure ±27.6 kPa (4 psi), Learn Mode, and at least a 1/4 graph signal strength displayed.
- If any of the parameters listed above are not displayed, replace the suspect tire pressure sensor.
- With the scan tool, verify tire pressure sensors ID and locations displayed on the scan tool match the IDs and locations recorded from the special tool.
- If the IDs and locations do not match, perform the Tire Pressure Indicator Sensor Learn .
- Enable the TPM learn mode. Use the J-46079
in simulate mode to learn 4 simulated sensor transmissions into the RCDLR. Verify that all 4 simulated sensor locations, IDs, and tire pressures displayed on the TPM special tool match the corresponding scan tool parameters displayed.
- If the scan tool does not match, replace the RCDLR.
- Test drive the vehicle above 40 km/h (25 mph) for greater than 2 minutes. With the scan tool, observe the suspect Pressure Sensor Mode data parameter. Verify the sensor mode changes to Rolling.
- If the Pressure Sensor Mode does not change, replace the suspect tire pressure sensor.
