2024-2025 Jeep/RAM TPMS Light On Dash TSB S2522000002

The Tire Pressure Monitoring System (TPMS) light illuminating on the dashboard is a common concern for owners of 2024-2025 Jeep and RAM vehicles. This issue, described in Manufacturer Communication S2522000002, frequently arises after aftermarket wheels or tires have been installed. The primary culprits identified are incorrect sensor orientation or the use of unverified replacement sensors.

Symptoms

Owners will typically observe the "TPMS Lights On Dash" warning. This indicates a potential problem with one or more tire pressure sensors, which are crucial for monitoring tire inflation and ensuring safe driving conditions. When the TPMS light is on, it means the system has detected an anomaly that requires attention.

Diagnosis and Trigger Conditions

Technicians have noted that the Tire Pressure Monitoring System (TPMS) issues often surface after a vehicle has had aftermarket wheels or tires installed. The problem can stem from several factors:

• Aftermarket Installations: The presence of non-OEM wheels or tires is a key indicator.
• Incorrect Sensor Orientation: Sensors might be mounted improperly, such as being reversed or rotated 180 degrees, which can hinder their ability to communicate correctly.
• Unverified Sensor Replacement: If original TPMS sensors were replaced with non-OEM or incompatible units, or if the replacement process was not followed correctly, it can lead to system malfunctions.
• Communication Issues: Incorrect sensor positioning can interfere with the RKE Mopar tool's communication and affect the vehicle's dynamic performance.

Repair Procedure Summary

To address the "Jeep Wrangler TPMS light" issue and resolve the "TPMS Lights On Dash" warning, technicians follow a structured diagnostic and repair process outlined in Manufacturer Communication S2522000002:

1. Inspect Vehicle for Aftermarket Wheels: The first step involves checking if aftermarket wheels or tires have been installed. Technicians will also determine if the original TPMS sensors were reused or replaced. They verify if the sensors respond to a TPM/RKE diagnostic tool. If sensors respond, their IDs are recorded and checked against the RFH-programmed IDs to ensure they match.

2. Remove the Tire and Inspect the Sensor: The tire is dismounted to allow for a visual inspection of the TPMS sensor. It's critical to confirm that the sensor is securely mounted and oriented correctly, not reversed or rotated 180 degrees. Figures in the communication illustrate the correct orientation markings and proper sensor positioning with markings facing upward. Incorrect positioning can lead to communication problems and improper dynamic performance.

3. Verify Sensor Identity: Technicians confirm that the sensor is an OEM part. A TPMS scan tool is used to verify that the sensor is active and transmitting a valid ID. If the sensor is incorrectly oriented, it is carefully removed and reinstalled according to approved service procedures to avoid damage. The position of the sensor is documented.

4. Reprogram Sensor IDs: If sensors were replaced or repositioned, they must be properly reprogrammed using the correct vehicle profile. This step ensures the vehicle's system recognizes the sensors and their unique IDs.

5. Confirm Dash Display Functionality: After installation and programming, technicians verify that all tire pressure readings appear correctly on the vehicle's dashboard display. This confirms that the system is now receiving and interpreting sensor data accurately.

6. Drive Confirmation: A final test drive of 10-15 minutes at speeds above 15 mph is performed. During and after this drive, technicians confirm that all tire pressure values are displayed correctly on the dash, ensuring the system is functioning as intended.
