Automatic Assignment of Sensor Location (AASL)
When sensors are relocated to a different position on the car, you can automatically reassign them to their
new position using the TPMS handset ‘Read’ function. For example, if the front wheels are swapped this
operation enables you to reallocate the sensor data in the receiver so that the values for the front left sensor
are now transmitted on the CAN ID for the front right. Consequently, the sensor data that is viewed on the
dashboard and logged is correct and will appear as the front right. Any sensor can be allocated to any of the
4 corner locations. The 4 sensors must have different serial numbers.
AASL function is enabled as follows:
•Press and hold the receiver button until it flashes twice then release. This puts the receiver into learn
mode where the 4 sensor locations are waiting for sensors to be assigned.
•Using the TPMS handset ‘Read’ function activate all 4 sensors in the correct order (FL,FR,RL then RR.)
The receiver LED will flash a number of times in quick succession as each sensor is allocated
correctly. A display of the sensor serial number on the TPMS handset does not guarantee it has also
been allocated a position within the receiver.
•Once a sensor serial number has been allocated to the first position (FL) the receiver is now ready to
accept the next sensor to be assigned as a (FR) then the (RL) and the (RR) As the receiver learns each
sensor serial number it will not allow it to be repeated in the next position.
•Finally press and hold the receiver button until it flashes 4 times to indicate the AASL is completed.
.
NOTES:
•The AASL operation does not change the sensor serial number only the revised allocation in the
receiver.
•The receiver will not function correctly if you exit from the AASL without allocating sensors to all 4
positions. When in normal operating mode any sensor that is read will activate the LED.
•In the event the TPMS handset is not available, the sensor allocation can also be achieved by
changing the tyre pressures. (the AASL function must be enabled.) You must avoid changing tyre
pressures on wheels that contain sensors and are within the reception range of the receiver.
•During the sensor allocation phase you can ‘Read’ each sensor more than once if you are uncertain if
the receiver has acknowledged the reception.
