NHTSA's summary
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. Another aftermarket device introducing RF noise around 433Mhz. Aftermarket GPS devices Aftermarket Wi-Fi hotspots Broken RFH antenna. Nonelectrical Aftermarket devices Steal reinforced tires. Metal Bedliner installed. After Market Tire Incorrect Installation of sensor in winter tires (example TPM upside down) Damages to sensor during tires service Aftermarket Metal splash shields Aftermarket stem valve cup Tinted Glasses (some of them contain metal).

| 9100867 Rev 1 | 2026-09-03. Service bulletin. MODULE Air Bag Control CAUTION: If ORC contains active or stored B2207 DTC AND the vehicle contains a Pulse module (or other 3rd party non-approved devices, see below for more details) - DO NOT SUBMIT ORC WARRANTY CLAIM. Please ensure vehicle voltage is within specified limits. Most faults will store after an ignition cycle if the vehicle voltage is within specified limits. Check TERMINAL RETENTION ON CONNECTOR C1 PIN 11, CIRCUT D 282 CAN FD+_2 and repair any loose connection. For Loss OF Communication faults, please follow the diagnostic service routine in Service Library and confirm these steps before ORC replacement. Reference Service Library Section 28 - DTC-Based Diagnostics / MODULE, Body Control (BCM) / Diagnosis and Testing / U0151-00-LOST COMMUNICATION WITH RESTRAINTS CONTROL MODULE. The Standard Procedure / COMMUNICATION DIAGNOSTIC PROCEDURE must be performed before replacing any component(s) or module(s). AT A MINIMUM THESE PROCEEDURES MUST BE CHECKED: 1). (Refer to 28 - DTC-Based Diagnostics/MODULE, Body Control (BCM) / Standard Procedure). 2). COMMUNICATIONS DIAGNOSTIC PROCEDURE - LOSS OF COMMUNICATION DIAGNOSTIC PROCEDURE If the vehicle has ORC fault B2207 - Occupant Restraint Controller Internal 1 either active or stored, please check for 3rd party (non-Mopar) installed "Pulse" unit at the CHMSL & Cargo Lamp wires. Please take the Service action to check & remove Pulse unit (or other 3rd party brands) spliced in circuit# L56, L14, L51, and/or ground Z946 for the Center High Mounted Stop Lamp (CHMSL) and Cargo Lamps. Please correct the wiring to original OEM standard and replace the ORC module. Please document the "Pulse" unit (and/or other device names for the same function) in the service repair history. The "Pulse" unit (or other brand names) is a 3rd party, non-MOPAR circuit that when spliced into the CHIMSL circuit, can make the CHIMSL blink 3 times before becoming solid on upon activation of the brake switch. Please do not submit warranty claim when the Internal-1 DTC is confirmed to be caused by the "Pulse" or similar unit. |
| 9100861 Rev 4 | 2026-08-26. Service bulletin. PUMP, Auxiliary Coolant, High Temperature Before replacing the High Temperature Auxiliary Coolant Pump, please perform the following steps: 1) Key ON/OFF and let the after-run pump run for at least 20 minutes before moving on to step #2. 2) Inspect the pump connector area for presence of water. 3) Inspect the pump connector for corrosion. 4) Inspect the pump for coolant contamination as this can cause the pump to stall. 5) Inspect battery terminals for damage to rule out a battery drainage issue. 6) Ensure the PCM is up-to-date with the latest available flash. |
