General Description

TPM Receiver is integrated with the TPM module installed in the crash pad assy-main (behind the Passenger Air bag module). The operating battery of TPM module is supplied from the vehicle battery.
The LOW-LINE TPMS Receiver unit's MCU and RF receiver circuits are active while the vehicle's ignition circuit is energized.
It continuously monitors for RF broadcasts from nearby WE units.
The TPMS Receiver unit has nonvolatile memory in which the ID codes of the WE units fitted to that particular vehicle are stored.
When the TPMS Receiver unit receives an information broadcast, it checks to see if the ID code contained within that broadcast matches one of the ID codes stored within its nonvolatile memory.
If this is the case, the TPMS Receiver applies the information contained within that broadcast to the TPMS Warning Algorithm.
This algorithm evaluates the pressure and temperature of each tire for changes over time and is responsible for making the decision to alert the driver to a potentially dangerous tire inflation condition via a visible 'TREAD' indicator.
In addition to processing data from the WE units, the TPMS Receiver is also capable of self-diagnosis of its circuitry and operating condition.

DTC Description

This DTC indicates that the Vehicle/receiver battery level is Low.
