TPMS Receiver

Description and Operation

Description

1. 1
   Mode

   1. Virgin State
      • The receiver is shipped in this state. Therefore, the replacement parts must be in this state.
      • In this condition, there is no auto slot, no sensor wake-up, no sensor monitoring, and no DTCs.
      • This state indicates that the platform settings must be written to the receiver and that the sensors have not been learned.
   2. Normal State
      • To check the tire inflation status and perform DTC checks, the receiver must be in this state.
      • In this state, sensor learning/detection is enabled automatically.
2. 2
   OVERVIEW

   • Learn the TPMS sensors for automatic low tire pressure monitoring.
   • Uses sensor information, distance traveled, ambient noise levels, auto learning status, output short circuit/poor contact status, vehicle battery charge level, and internal receiver status to determine whether there is a malfunction in the vehicle or system.

Operation

1. 1
   GENERAL FUNCTIONS

   • Automatic learning occurs only once per ignition cycle.
   • At the end, the IDs of the 4 wheel sensors are entered into memory for monitoring.
   • While automatic learning is completed, previously learned sensors are checked for underinflated/leaking tire warnings.
2. 2
   General Conditions for Learning New Sensors:

   • The receiver must confirm that the sensor is not temporary. a. Uses vehicle speed. b. Previously used sensor reliability reduction learned.
   • Typical time of continuous driving at a speed above 15.5 mph (25 km/h) for learning a new sensor is longer than 20 minutes.
3. 3
   General Conditions for Unlearning a Deleted Sensor:

   • It takes less than 20 minutes at a speed of 15.5 mph (20–30 km/h).
   • Loss of reliability depends on the time the vehicle travels at a speed greater than or equal to 12.4 mph (20 30 km/h).

Repair Procedures

REPLACEMENT

1. 1
   Disconnect the negative (-) battery cable.
2. 2
   Place a cover under the protective gasket. (Refer to Body - Instrument Panel)
3. 3
   Disconnect the connectors from the Body Control Module (A).

   

4. 4
   Loosen the screw and remove the body control module (A).

   

5. 5
   To install, perform the removal procedure in reverse order.
6. 6
   Perform machine learning using GDS.
7. 7
   Check TPMS using GDS.

ITEM

Diagnostic procedure with scan tool

1. 1
   Connect the self-diagnosis connector (16-pin) located at the lower part of the instrument panel to the self-diagnosis tool, then turn on the ignition and activate the tool.
2. 2
   Select "Vehicle Model" and "TPMS" on the GDS vehicle selection screen, then press OK. [Record sensor ID]
