Tire Pressure Sensor Learn with EL-52545 (Preferred)

The EL-52545 allows the tire pressure sensors to be learned without transmitting RF data between the tire pressure sensors and the vehicle. When using the EL-52545 each tire pressure sensor ID is learned to the EL-52545 and stored internally. The EL-52545 is then connected to the vehicle DLC using the OBD2 Interface Module, which is part of the EL-52545 kit. The stored tire pressure sensor information will then be loaded into the K9 Body Control Module. Using the EL-52545 to learn tire pressure sensors will prevent the vehicle from learning errant nearby tire pressure sensor from other vehicles in a service facility environment, especially if the tire pressure sensor batteries are low. This is the GM recommended method to learn tire pressure sensors.

1. Turn on EL-52545
2. Select RDR from the on-screen display
3. If available, scan the QR code on the vehicles tire placard or certification label. If QR is not available, select MMY from the on-screen display and manually input the vehicle information.
   NOTE: Make sure the TPM tool battery is sufficient to complete TPM learn process. Do not place the TPM tool directly on the valve stem. The TPM tool should be placed against the tire sidewall near the valve stem. The TPM sensor learn activation procedure may have to be repeated up to 3 times before determining a sensor is malfunctioning.
4. Approach the vehicle starting with the left front tire and read each tire pressure sensor information by pressing the green trigger button with the EL-52545 located near the tire valve stem. Read each tire pressure sensor in the order identified on the EL-52545.
   NOTE: If any sensors display "Sensor Not Compatible" on the EL-52545 screen, you will need to first make sure compatible sensors are installed on the vehicle.

   → If any tire pressure sensors do not respond 

   Replace the tire pressure sensor only after several attempts have been made to identify all sensors. Undetected sensor will be identified with "No Sensor Detected" displayed in the table. After sensor replacement rerun RDR procedure.

   ↓ If all tire pressure sensors do respond 

5. Verify the BAT value for each tire pressure sensor in the table on the EL-52545 is OK

   → If not OK 

   Replace the tire pressure sensor and rerun RDR procedure.

   ↓ If OK 

6. Verify the pressure and temperature values are reasonable based on the ambient conditions and actual tire pressure.

   → If either value is inaccurate 

   Replace the tire pressure sensor and rerun RDR procedure.

   ↓ If both values are accurate 

7. Ignition On/Vehicle in Service Mode.
8. Connect the EL-52545 OBD2 Interface Module to the EL-52545.
9. Verify the OBDII icon is displayed on the EL-52545 and the green com LED is flashing on the EL-52545 OBD2 Interface Module.
10. Connect the other end of the OBD2 Interface Module to the vehicle DLC.
11. Select OK on the EL-52545 and follow the on-screen instructions.
