TPMS Sensor Training Techniques

Wheel Rotation and Sensor Training Techniques 

Training known good sensors from another vehicle cannot differentiate between a faulted module and RFI, as some noise source could be preventing the module from receiving the tire pressure status from the original sensors as well as the known good sensors. However, this technique can be used to differentiate between a faulted module and a faulted sensor.

If the module in the suspect vehicle cannot train any of the suspect sensors and, likewise, cannot train known good sensors from a known good vehicle, then the concern is with the suspect module or RFI and not with the original sensors. The original sensors should not be replaced.

If a sensor in a certain location has caused several events, yet the sensor trains and seems to operate normally, moving the suspect wheel-sensor to a different location on the vehicle is a good way to isolate the concern to a certain wheel-sensor location. Rotate the wheels and road test the vehicle. This can be done in an attempt to replicate the concern and help determine if the concern followed the sensor or remained in the original sensor location.

If the vehicle has been stationary for more than 30 minutes, the sensors go into a "sleep mode" to conserve battery power and need to be "woken up" so they transmit the latest tire pressure information to the BCM.

Refer to: Tire Pressure Monitoring System (TPMS) Sensor Activation  (Tire Pressure Monitoring System (TPMS), General Procedures).

Training Sensors in a Different Order 

If the first sensor fails the TPMS training procedure, the BCM aborts the entire procedure. Starting the training procedure at a different wheel is a technique that can be used to determine if the remaining sensors can train to the module. This can help save time determining if one sensor is damaged, other sensors are having concerns or the BCM is experiencing training difficulties with a certain TPMS sensor location.
