This procedure relearns the Tire Pressure Monitoring System (TPMS) sensors on a 2014 Ram 2500 with 6.7L Cummins diesel engine after tire rotation, sensor replacement, or pressure adjustment.

Warnings

Tools required

Preparation

1. Park vehicle on level ground and apply parking brake
2. Turn ignition to OFF position
3. Verify all four tires plus spare (if equipped with TPMS) are inflated to the pressure listed on the driver door jamb placard
4. Ensure TPMS sensors are properly installed and functional in all wheel positions
5. Have vehicle identification number (VIN) available if using advanced diagnostic scanner

Procedure

1. 1

   Verify tire pressures
   Using a calibrated tire pressure gauge, check and adjust all four tires to the recommended pressure listed on the driver door jamb placard. For the 2014 Ram 2500, this is typically 60-65 PSI front and 60-80 PSI rear depending on load, but verify on the specific vehicle placard. If equipped with a TPMS-monitored spare tire, adjust it to the specified spare tire pressure as well.
2. 2

   Turn ignition to ON position
   Insert key and turn ignition to the ON/RUN position without starting the engine. Do not press the brake pedal if equipped with push-button start. The instrument cluster should illuminate and the TPMS warning light should be visible.
3. 3

   Access TPMS relearn mode using button method
   If your vehicle is equipped with the manual relearn button: Press and hold the TPMS reset button located beneath the steering column or in the glove box until the TPMS warning light blinks three times, then release. The horn will chirp once to indicate the vehicle has entered relearn mode. The left front turn signal will illuminate to indicate the system is ready to learn the left front sensor position.
4. 4

   Activate left front sensor
   Starting at the left front tire, use a TPMS activation tool to trigger the sensor by holding the tool against the tire sidewall near the valve stem. The horn will chirp once to confirm the sensor has been learned. The left front turn signal will turn off and the right front turn signal will illuminate, indicating the system is ready for the next sensor.
5. 5

   Activate right front sensor
   Move to the right front tire and activate the TPMS sensor using the same method. Wait for the horn chirp confirmation. The right rear turn signal will illuminate next.
6. 6

   Activate right rear sensor
   Move to the right rear tire and activate the TPMS sensor. Wait for the horn chirp confirmation. The left rear turn signal will illuminate next.
7. 7

   Activate left rear sensor
   Move to the left rear tire and activate the TPMS sensor. Wait for the horn chirp confirmation. After the left rear sensor is learned, the horn will chirp twice and all turn signals will flash briefly to indicate successful completion of the relearn procedure.
8. 8

   Alternative: Use diagnostic scanner method
   If the manual button method is not available or fails, connect a compatible OBD-II diagnostic scanner with TPMS functionality to the vehicle's diagnostic port located under the driver side dashboard. Navigate to the TPMS relearn or sensor ID programming menu. Follow the on-screen prompts to enter relearn mode and activate each sensor in the order specified by the scanner (typically LF, RF, RR, LR). The scanner will confirm successful learning of each sensor position.
9. 9

   Complete relearn procedure
   Turn the ignition to the OFF position. Wait at least 30 seconds before restarting the vehicle. This allows the TPMS system to save the new sensor positions to memory.
10. 10

    Start engine and verify
    Start the engine and observe the instrument cluster. The TPMS warning light should illuminate briefly during the bulb check, then extinguish after approximately 5-10 seconds. If the light remains on or flashes, the relearn procedure was not successful and must be repeated.

Reassembly

1. No reassembly required for this procedure

Verification

• Confirm the TPMS warning light extinguishes within 10 seconds of starting the engine
• Drive the vehicle at speeds above 20 MPH for at least 10 minutes to allow the system to fully initialize and verify all sensor positions
• Use a diagnostic scanner to verify all four (or five if spare is monitored) sensor IDs are correctly stored in the TPMS control module
• Check that individual tire pressure readings are displayed correctly in the instrument cluster or vehicle information center if equipped
• Verify no TPMS-related diagnostic trouble codes are present in the system
