SUBJECT VEHICLE: 2007-10 GM Escalade.

RELEARN PROCEDURE? Yes.

SPECIAL TOOLS NEEDED? Yes, a J-46079 Tire Pressure Monitor Diagnostic Tool.

The tire pressure monitoring system (TPMS) on 2007-2010 General Motors Escalades displays individual tire pressures and their locations on the Driver Information Center (DIC).

In addition to the DIC, the Escalade’s TPMS uses the Powertrain Control Module (PCM), the Body Control Module (BCM), an Instrument Panel Cluster (IPC), a Remote Control Door Lock Receiver (RCDLR) and a radio frequency (RF) transmitting pressure sensor in each wheel/tire assembly.

The RCDLR receives and translates the data contained in each sensor transmission, then sends the tire pressure and tire location data to the DIC for display. When the TPMS detects a significantly under-inflated tire pressure, a “Check Tire Pressure” message is displayed on the DIC and the low tire pressure indicator is displayed on the IPC.

Remove, identify, replace

To remove an old sensor, follow these steps. CAUTION: The tire should be demounted from the wheel using the tire changer manufacturer’s instructions. Use the following information to avoid damage during the demounting/mounting process.

NOTE: When the wheels have been rotated, or a tire pressure sensor or RCDLR has been replaced, retrain the tire pressure sensor.

There are currently two different kinds of sensors in use on 2007-10 Escalades. Identification of which sensor is in use can easily be made after the tire has been removed from the wheel by referring to Figure 1 and Figure 2.

1. Raise the vehicle on a suitable support. Remove the tire/wheel assembly from the vehicle.

2. Demount the tire from the wheel following the tire changer manufacturer’s instructions while paying special attention to the following steps to avoid damaging the tire pressure sensor.

a. Place the sensor’s cap and valve on a dry, clean surface after removal. The cap is aluminum and the valve is nickel-plated to prevent corrosion. DO NOT substitute a cap or valve made of any other material.

b. Position the bead braking fixture 90 degrees from the valve stem when separating the tire bead from the wheel.

c. Position the mounting/demounting head so the tire iron (or pry bar) can be inserted slightly clockwise of the sensor body when prying the tire bead up and over the mounting/demounting head.

d. Using the tire machine, rotate the tire/wheel assembly clockwise when transferring the tire bead to the outside of the wheel rim.

e. Repeat steps a-d for the inner bead.
