Manufacturer summary

Original wording in English

DT25 TPMS Issues - TPMS not working, TPMS working intermittently, TPMS displaying wrong values, TPMS warnings on cluster In case of TPMS concerns, please follow the below: - Verify that the 12V Vehicle battery is good, as low or dead batteries may cause TPMS to not function as designed. - Verify if the RFHM and IPC SWs are up to date. If not, update to the latest SW versions. - Disconnect the Remote Start Antenna Coaxial cable, wait for a minute and plug it back in and verify if the antenna is working as expected, as any issues with it can cause TPMS and Fob issues. - Study the Remote Start Antenna wiring for pinches or damages, as any of these can cause issues with the TPMS and the fob functions. - Perform TPMS Autolearn Procedure After Tire Rotation or Tire Change for Sensata TPM sensors. - Verify if the sensor IDs are correct. If they are incorrect, autolearn the sensors. (Autolearn Procedure - Drive over a speed of 25Kmph or 15 Mph for 20 mins) - If there are any issues in terms of tire pressure, inflate or deflate to the recommended pressure. - If DTCs - C15CB00 ("Front Axle Tire Pressure Placard Implausible") and/or C15CC00 ("Rear Axle Tire Pressure Placard Implausible") are being triggered, program the placard values. Also, check if the placard values were programmed previously. - Please make sure that the Tire placard values match the recommended tire pressure values in case of any TPMS concern. - If the sensors are loose, fix them to the wheel properly. - If an RFH is replaced for any other concern, please program the TPMS sensor IDs into the new RFH and perform the autolearn procedure. - If there are aftermarket parts that can potentially affect the TPMS functions, any repairs will not be considered for warranty. - Aftermarket parts that can impact TPMS functioning: Electrical LED LIGHTING RV equipment, Rear cameras (After Market) Toll Road Transponder Transceivers radios such as FRS /CB. DC/AC inverter Wiring loose grounds. After-market added wiring causing RF coupling Off road / Uplift modifications Aftermarket illuminated splash shields. RFH antenna disconnected.
