Kia TPMS Sensor Replacement
If a sensor proves faulty or is damaged then it will need to be replaced. This requires a new sensor to be fitted and the EVIC/WCM to be reprogrammed with its unique ID and its position on the vehicle. The procedures for all vehicles including Kia vehicles are illustrated in the Bartec Tire Pressure Monitoring Systems Guide which shows service requirements, reset procedures, dismounting/mounting instructions, torque specifications etc for all makes/models and years. The relearning process will also be required in the event of wheel rotation. The relearn process is different across the Kia/Dodge/Jeep family of vehicles and also varies from the early vehicles with TPMS fitted. The different techniques are set out from information provided by the manufacturer in the Bartec Tire Pressure Monitoring Systems Guide. On most models the static relearn process requires 'RETRAIN TIRE SENSORS_YES' to be selected on the EVIC followed by activating each TPMS in turn (LF, RF, RR, LR) enabling each of the TPMS unique ID numbers to be loaded into the WCM. Remember that the TPMS tool should be held on the tire adjacent to the valve stem and not directly over the TPMS when activating the sensor. Each time a code has been successfully loaded the horn acknowledges. Repeat the procedure until all TPMS have been programmed into the WCM as displayed on the EVIC which should now display 'TRAINING COMPLETE'. Exit the training procedure.
The technician should always: refer to manufacturer's specifications for proper torque requirements when replacing nuts and valve cores; use new grommets, nuts, plastic or nickel-plated valve caps and electro-less, nickel-plated valve cores when performing any tire service; never use a brass valve core or un-plated brass cap with an aluminium TPMS sensor stem. Contact between dissimilar metals can cause galvanic corrosion, which can lead to loss of air pressure.
Note: The technician should avoid the use of any liquid or tire sealant injected into tires equipped with TPMS as this may block the pressure port and cause malfunction. If evidence of the use of tire sealant is noted upon dismounting the tire, it is highly recommended that the TPMS are replaced. It is also very important to remove all residual sealant from the inside of the tire and rim surfaces prior to re-installing the tire.
Following reprogramming of the WCM a further audit of the car is recommended to produce evidence of the work carried out.
