MTD January 2016 TPMS Tire pressure sensor retraining Te WCM automatically learns and stores the sensor's ID while driving afer a sensor has been replaced. Tere is no formal retraining procedure necessary. Te WCM automati- cally learns and stores the sensor IDs while driving within 10 minutes continuously above 15 mph (24 km/h) afer a sensor has been replaced. Te learning sequence will initiate when the vehicle has been stopped for more than 20 minutes. If a sensor cannot be trained, see appropriate manufacturer service information. NOTE: A new sensor ID can also be programmed directly into the WCM by using a TPM-RKE analyzer in conjunction with a scan tool. Once the new sensor ID has been programmed, the TPM-RKE analyzer can be used to update the TPMS by activating the sensor. Demounting/mounting procedures CAUTION: Te TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been estab- lished for the tire size equipped on the vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type or style. Afermarket wheels can cause sensor damage. Do not use afermarket tire sealants or balance beads if the vehicle is equipped with TPMS, as damage to the sensors may result. NOTE: If tires require leak-testing, a water test may be used to check for a leak around the sensor, as long as any water at the valve core is removed when the procedure is completed. Water can be expelled from the core area by pushing in on the core for several seconds, allowing escaping air to drive out any moisture. Reinfate the tire as necessary. Install the original valve stem cap. Tire pressure sensor IMPORTANT: Te domestic TPMS operates on a 315 MHz radio frequency. Te 315 MHz sensors can be easily identifed by a white outline oval (black center) insignia on the sensor Figure 2: Identifying tire pressure sensor components. Quik-Link: 800-687-1557 ext. 11141 84
