E6 CHECK THE TIRE PRESSURES USING THE BCM (BODY CONTROL MODULE) TPMS (TIRE PRESSURE MONITORING SYSTEM) SENSOR PARAMETER IDENTIFICATIONS (PIDS)
Using a diagnostic scan tool, view the following BCM Parameter Identifications (PIDs):
Left Front Tire Pressure (TPM_PRES_LF) Right Front Tire Pressure (TPM_PRES_RF) Left Rear Tire Pressure (TPM_PRES_LRO) Right Rear Tire Pressure (TPM_PRES_RRO)
Do the tire pressures indicated by the Parameter Identifications (PIDs) match the tire pressures measured previously, ±20.7 kPa (3 psi)?
Yes | The system is operating normally at this time. The concern may have been caused by an incomplete or incorrectly performed sensor calibration or low tire pressure. | |
|---|---|---|
No | INSTALL a new TPMS sensor(s) for the sensor(s) displaying inaccurate tire pressure. REFER to: Tire Pressure Monitoring System (TPMS) Sensor (204-04B Tire Pressure Monitoring System (TPMS), Removal and Installation). | |
The BCM Does Not Enter TPMS Sensor Training Mode
Normal Operation and Fault Conditions
The training (calibration) can be carried out manually or by using a diagnostic scan tool, REFER to: Tire Pressure Monitoring System (TPMS) Sensor Location Calibration (204-04B Tire Pressure Monitoring System (TPMS), General Procedures).
When one or more new TPMS sensors are installed or a new BCM is installed, the sensors must be trained (calibrated) to the BCM. For the manual training procedure, the BCM must receive a valid ignition signal, a valid brake pedal position signal and a valid vehicle speed signal. The start-stop switch signal and the brake pedal position signal are both direct inputs to the BCM, the vehicle speed signal is sent to the BCM from the PCM over the HS-CAN1.
If the vehicle has been stationary for more than 30 minutes, the TPMS sensors enter a "sleep mode" to conserve battery power. It becomes necessary to wake them up so they transmit the latest tire pressure information to the RTM. REFER to: Tire Pressure Monitoring System (TPMS) Sensor Activation (204-04B Tire Pressure Monitoring System (TPMS), General Procedures).

Visual Inspection and Diagnostic Pre-checks
Inspect for customer electronic devices, such as a cell phone charger or GPS unit. Inspect for non-Original Equipment Manufacturer (OEM) wheel or run-flat tires.
