Subaru 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 ECU to be reprogrammed with its unique ID and its position on the vehicle. The procedures for all 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 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 to the Subaru vehicle.
The Subaru range of cars unlike most vehicles made in North America do not have an inbuilt relearn mode to enable the vehicles to relearn the TPMS IDs when a TPMS repair tool is used to activate the sensor. It is important therefore to have access to a Bartec Tech600Pro tool which is able to diagnose Subaru TPMS issues and also has an extra interface to the vehicle OBDII/CANbus to communicate with the vehicle Engine Control Unit (ECU) and download the TPMS data. The Tech600Pro has this feature.
Finally when the TPMS replacement procedure is complete it is good practice to do a final audit and print the results out for the customer. This completes the circle for your liability protection (showing the job has been completed professionally) and affirms your technical reputation with the customer.
