Using a diagnostic scan tool, carry out the BCM Diagnostic Trouble Codes (DTCs).
Is DTC B124D:02 present?
| No |
If the TPMS warning indicator is illuminated and the message center is displaying low tire pressure, GO to E3
If the TPMS warning indicator is not illuminated and the message center is not displaying low tire pressure, the system is operating correctly at this time. The concern may have been caused by RFI. For information on locating sources of RFI,
REFER to: Tire Pressure Monitoring System (TPMS) - System Operation and Component Description (204-04B Tire Pressure Monitoring System (TPMS), Description and Operation).

|
| E3 CHECK FOR SPARE TIRE IN USE |
-
NOTE:
A spare tire cannot be programmed to the
vehicle. If a damaged road wheel is located in the vehicle and the RTM cannot communicate with it, or if the damaged wheel has been dropped off at a repair facility, the BCM sets a TPMS sensor fault. Repair and remount the road wheel as necessary to restore system operation.
Check the spare tire location.
Is the spare tire in use?
| Yes |
REPAIR and REMOUNT the wheel to the vehicle.
REFER to: Wheel and Tire (204-04A Wheels and Tires, Removal and Installation).
ADJUST tire pressures to the required pressure as defined on the VC label.
|
|
| E4 CHECK FOR LOW TIRE PRESSURE |
-
Measure and record the pressure in all 4 tires using a digital tire pressure gauge.
-
Adjust the pressure for those found to be below the specification listed on the VC label.
-
To clear the low pressure warning indicator, drive
the vehicle for at least 2 minutes above 32.2 km/h (20 mph) or activate
each sensor at least twice.
REFER to: Tire Pressure Monitoring System (TPMS) Sensor Activation (204-04B Tire Pressure Monitoring System (TPMS), General Procedures).
Do not train the sensors at this time.
Has the TPMS warning indicator gone out?
| Yes |
The system is operating correctly at this time. The cause was low tire pressure.
|
|
| E5 TRAIN ALL 4 TPMS (TIRE PRESSURE MONITORING SYSTEM)
SENSORS |
-
Train all 4 TPMS sensors.
REFER to: Tire Pressure Monitoring System (TPMS) Sensor Location Calibration (204-04B Tire Pressure Monitoring System (TPMS), General Procedures).
Did all of the TPMS sensors train and did the horn sound when each sensor was trained?
|
| E6 CHECK THE TIRE PRESSURES USING THE BCM (BODY CONTROL MODULE)
TPMS (TIRE PRESSURE MONITORING SYSTEM)
SENSOR PARAMETER IDENTIFICATIONS (PIDS) |
-
Activate each TPMS sensor.
REFER to: Tire Pressure Monitoring System (TPMS) Sensor Activation (204-04B Tire Pressure Monitoring System (TPMS), General Procedures).
-
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).
