Tire Pressure in Cold weather specificationsMitchell 1 provides TPMS information to Modern Tire Dealer, an award-winning publication that writes editorial content geared to independent tire dealers. We’re sharing this content in our blog, with a link to the Modern Tire Dealer website where you can read the article in full. The TPMS information in this article may also be accessed in the reset procedures tab in our ProDemand® auto repair information software, along with other important reset procedure data for the selected vehicle.

SUBJECT VEHICLES: 2007-2016 GM/Cadillac Escalade.


SPECIAL TOOLS NEEDED? A TPMS sensor activation tool (J-46079) may be used in place of increasing/decreasing pressures to enable the sensor.

The tire pressure monitoring system (TPMS) on 2007 to 2016 GM/Cadillac Escalade Series system uses the remote control door lock receiver (RCDLR), body control module (BCM), four radio frequency (RF) transmitting pressure sensors, and the serial data circuit to perform the sensor learn mode functions.

The sensor learn procedure must be performed any time the RCDLR is replaced, a sensor is replaced, or after the vehicle’s tires have been rotated. Once the learn mode has been enabled, each of the sensor’s unique identification (ID) codes can be learned into the RCDLR’s memory. When a sensor’s ID has been learned, the RCDLR sends a serial data message to the BCM to sound a horn chirp. This verifies the sensor has transmitted its ID, and the RCDLR has received and learned it.

Each sensor takes a pressure measurement sample once every 30 seconds while in stationary mode. If the tire pressure increases or decreases by more than 1.6 psi (11 kPa) from the last pressure measurement, another measurement will occur immediately to verify the change in pressure. If a pressure change has indeed occurred, the sensor transmits in learn mode. When the RCDLR receives a learn mode transmission while in learn mode, it will assign that sensor ID to the location on the vehicle relative to the order in which it was learned. The RCDLR must learn the sensor ID codes in the proper sequence in order to determine sensor location. The first learned ID is assigned to left front, the second to right front, the third to right rear and fourth to left rear.

The TPMS will cancel the learn mode if more than two minutes have passed and no sensors have been learned, or if the system has been in learn mode for more than five minutes. If the learn mode is canceled before any sensor has been learned, the RCDLR will remember all current sensor IDs and their locations. As soon as the first sensor ID code is learned, all other IDs are erased from the RCDLR’s memory.

The updated tire pressures will not be displayed on the DIC until the RCDLR receives two more valid transmissions from each sensor. After performing the reset procedure below, always test drive the vehicle above 25 mph for at least two minutes before viewing tire pressures on the DIC. When the vehicle is stationary, the sensors go into stationary mode. In this mode, the sensors transmit once every 60 minutes to minimize sensor battery consumption. As vehicle speed increases to 25 mph (40 km/h), the sensors go into drive mode, in which they transmit once every 60 seconds. NOTE: The sensor’s pressure accuracy is about 2 psi (14 kPa) at temperatures from 14 to 158 degrees Fahrenheit (-10 to 70 degrees Celsius).

Tire pressure monitor warning indicators

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. This DIC message will also set if a spare tire is in use. The DIC will display the “SERVICE TIRE MONITOR” message if one or more of the tire pressure sensors has malfunctioned or if all of the sensors have not been programmed successfully. If the warning indicators are still on, there is a problem in the TPMS. See the appropriate service information.

When the tire pressure warning light illuminates and a warning message appears, immediately check air pressure of all tires and adjust to the specified pressure. Drive the vehicle above 25 mph (40 km/h) for a few minutes. If the warning indicators are still on, there is a problem in the TPMS. See the appropriate service information.

Reset procedures

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