Factory service manual
From the 2008 KK factory manual — descriptions, specs, torque & procedures for this part.
WIRELESS CONTROL MODULE (WCM)
The receiver circuit for the TPM system is integrated into the WCM for non-remote start vehicles. For factory installed remote start vehicles, the remote start antenna is external to the WCM. In addition to Tire Pressure Monitoring System (TPMS), The WCM can also include the Remote Keyless Entry (RKE) receiver, Remote Start (if equipped), and the Sentry Key Immobilizer (SKIM) receiver. All four receivers share a number of common components. The WCM decodes the RF signals transmitted by each of the vehicle's tire pressure sensors. The decoded information is used to determine if "warning" or "fault" conditions exist within the TPM system.
The WCM communicates with the module that controls the "TPM telltale lamp" and the text display (Premium system), via the vehicle bus system.
Upon detection of a warning or fault condition, the WCM will send a request to illuminate or flash the yellow TPM telltale. Also, upon detection of a warning or fault condition, the display module will send a request to sound the "chime". A chime will only be requested once per ignition cycle per warning or fault condition detected.
The WCM will store all warning and fault conditions, placard pressure values, low-pressure threshold values and low pressure threshold hysteresis values in memory that can be accessed through diagnostic communication. If new sensors are introduced to the vehicle, the data stored for the sensor being replaced will be deleted.
The WCM will store all wheel sensor ID's and locations and faults in memory that can be accessed through diagnostic communication. All other data values transmitted from each active wheel sensor (not the spare tire) shall be stored in the WCM memory.
The WCM automatically learns and stores the sensor's ID while driving "within 10 minutes continuously above 15 m.p.h. (24 Km/h)" after a sensor has been replaced. A new sensor ID can also be programmed directly into the WCM by using a RKE-TPM Analyzer in conjunction with a Scan Tool. Once the new sensor ID has been programmed, the RKE-TPM Analyzer can be used to update the TPMS by activating the sensor.
The learning sequence will initiate when the vehicle has been stopped for more then 20 minutes.
TRANSPONDER - TIRE PRESSURE📷 1
A transponder is located in three of the four wheel wells of the vehicle to provide the WCM/SKREEM with the location of the tire pressure sensors on the vehicle. The transponders are located in the left front, right front and left rear wheel wells. A fourth transponder is not necessary in the remaining wheel well due to the process-of- elimination theory. Once the system knows the location of the first three sensors it assumes the location of the fourth tire pressure sensor is in the left rear tire.
