TPMS Relearn Process How Involved is the Re-learn Process? Stationary 25% Uses an activation tool with the car in “re-learn” mode. New ID’s can be programmed without driving the vehicle. OBD 36% An activation tool in conjunction with a scan tool is required to program new sensor ID’s into the vehicle. New ID’s can be programmed without driving the vehicle. Auto learn 39% Vehicle can learn a single new ID and in some cases multiple new ID’s without the use of a tool. Requires driving the car in order to turn off the light. Less than 40% of the vehicles can re-set themselves. Many “Auto Learns” can only do 1 new TPMS Sensor. More than 60% of TPMS vehicles require an activation or activation/scan combination tool! View relearn examples: Typical Chrysler Relearn Considered an “Easy” Relearn Process Must write ID number down before installation If sensor is installed before retrieving new ID number then technician would need to break down the tire to retrieve the number Plug in scan tool to OBDII port on car Build vehicle specifications in the tool Go to TPMS relearn function in tool Enter new TPMS ID numbers in tool Must be entered one at a time Exit out of tool Install TPMS sensors Drive vehicle – Up to 45 minutes With the Standard Clone-able TPMS Sensors: You clone it, you install it, and you drive away! Typical Lexus/Toyota Relearn Need TPMS tool to read all ID numbers off old sensors Once learning is initiated it will wipe all ID numbers (TSB L-SB-0025-09) If technician fails to get the ID numbers at the start – he will need to break down all four tires to get number off sensor (1-1/2 hours) Need factory scan tool to initialize reprogramming procedure Plug factory scan tool into OBDII port on vehicle Initialize learning procedure Learning procedure takes approx.15 different steps Technician interaction on a pc Approximate time with no issues ½-1 hour With the Standard Clone-able TPMS Sensors: You clone it, you install it, and you drive away! Auto-Learn Process Install sensor in vehicle (no ID number required) Drive vehicle 15-45 minutes until light resets During the drive the system will learn the new sensor ID. If the vehicle has been stationary for more then 20 minutes Vehicle must be driven for a minimum of 10 minutes Maintain a continuous speed above 15 mph The problem is that it doesn’t always work Relearn will not always initialize on its own With the Standard Clone-able TPMS Sensors: You clone it, you install it, and you drive away!
