TPMS Sensor Training Techniques
TPMS Sensor Training Techniques
Wheel Rotation and Sensor Training Techniques
Training known good sensors from another vehicle can help determine whether the concern is with a sensor, the RTM or GFM. This technique cannot help determine whether the concern is due to RFI as some RFI source could be preventing the RTM or GFM from receiving the tire pressure status from the known good sensors as well as the original sensors.
If the RTM or GFM in the suspect vehicle cannot train any of the original sensors and, likewise, cannot train known good sensors from another vehicle, then the concern is with the 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 that particular wheel to a different location on the vehicle is a good way to isolate the concern to a certain sensor/wheel 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 RTM. Refer to: Tire Pressure Monitoring System (TPMS) Sensor Activation .
Training Sensors in a Different Order
If the first sensor fails the TPMS training procedure, the BCM or GFM aborts the entire procedure. Starting the training procedure at a different wheel is a technique which 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 or GFM is experiencing training difficulties with a certain TPMS sensor location.
