TPMS Retrain, reset when replacing Durango sensors Wait for indicator lamp to go out when adjusting pressure SUBJECT VEHICLE: 2007-09 Dodge Durango. RELEARN PROCEDURE? Yes. SPECIAL TOOLS NEEDED? Yes, a TPM-RKE Analyzer tool to program sensor IDs. a unique 32-bit ID, to a central receiver circuit located inside the Wireless Control Module (WCM). If a warning or fault condition exists, the WCM will send a message request to illuminate the low pressure warning light and to sound a chime. NOTE: If a tire pressure sensor has been replaced, the tire pressure sensors must be retrained. See reset procedures. Te TPMS remains active even if no tire pressure-related message is displayed. Te sensors lay dormant (park mode), then wake and start transmiting (drive mode) when the vehicle frst reaches speeds over 15 mph. Once the wheels stop rotating for a period of approximately 20 minutes, the sensors shut down until again awakened. While in park mode, the sensors still transmit approximately once every 13 hours to let the receiver know air pressure status at that time. If a system fault is detected, the indicator light will fash on/of for 60 seconds. Warning, warning! The tire pressure monitoring system (TPMS) on the 2007-09 Dodge Durango monitors air pressure in the four road tires and the spare tire (if the vehicle is equipped with a full-size spare). Te TPMS uses radio and sensor technology to monitor tire air pressure levels. Sensors, mounted to each road wheel as part of the valve stem, monitor tire pressure, air temperature inside the tire, wheel acceleration and the sensor internal batery status for all four active road tires. Te sensor will broadcast this information, along with Figure 1: Identifying tire pressure sensor components (1 of 2). 70 If the warning light is lit continuously due to low pressure in one or more tires, adjust tire infation to specifcation. Te light will remain on until the tire pressure is properly set. NOTE: Tire pressure may increase from 2 psi to 6 psi during normal driving conditions. Do not reduce this normal pressure build up. Afer adjusting air pressure in a tire, allow approximately two minutes for the message or indicator lamp to go out. Figure 2: Identifying tire pressure sensor components (2 of 2). MTD March 2013
