WARNING: DEATH OR SERIOUS INJURY CAN OCCUR IF MAGNETICALLY SENSITIVE DEVICES ARE EXPOSED TO THE RELEARN MAGNET. MAGNETS CAN AFFECT PACEMAKERS. CAUTION: Never attempt to train more than one vehicle at a time. System is capable of reading tire pressure sensor transmissions from other nearby vehicles while in train mode. Each time a wheel rotation or tire pressure sensor replacement occurs the tire pressure sensors must be retrained. This is necessary to inform the Electronic Vehicle Information Center (EVIC) that a sensor change was made and the new locations of the sensors. Retraining is accomplished through the EVIC used in conjunction with a Re-learn Magnet, Special Tool 8821. NOTE: Use the following procedure to retrain all five (5) tire pressure sensors. No attempt should be made to retrain individual sensors. # Retrieve Re-learn Magnet, Special Tool 8821. # Press MENU Button on EVIC until "RETRAIN TIRE SENSORS - NO" is displayed. # Press STEP button to select "YES". There is a 60 second timer for training the first sensor and a 30 second timer between training the remaining sensors. If either of these timers expire, the EVIC will abort the training procedure. If at any time the EVIC display reads "TRAINING ABORTED", move the vehicle ahead at least one foot and repeat the entire retraining procedure. # Press MENU button to start retraining. Display will read "TRAIN LEFT FRONT TIRE" NOTE: The order for retraining all five sensors is: * Left Front * Right Front * Right Rear * Left Rear * Spare # Starting at left front tire, place Re-learn Magnet over valve stem. Within approximately 5 seconds, vehicle horn will chirp indicating training complete for that particular sensor. Remove the magnet. # Repeat step (6) on remaining sensors as indicated by EVIC until all five TPM sensors positions are trained. # Once EVIC displays "TRAINING COMPLETE", pressing either STEP, C/T, RESET or MENU button will exit training routine.

IF the pressure is set correctly all you have to do is drive it for 15 minutes for it to update. If it doesn't update one of hte sensors may be bad and you will have to take in for service.

You need your sensor trainer and you do it from the electronic overhead console. Pick retrain tires and follow the cars instructions. You have to have the little donut like black component, mine was on the jack that came with my jeep. It goes over the valve stem.

What sensors does the robot have?

The sensors that an engineer puts on a robot are entirely dependent upon the functions that the engineer perceives that the the robot will be called upon to perform. Some, but not all, of the sensors may be: proximity sensors, pressure sensors, light sensors, magnetic sensors, a camera, temperature sensors, accelerometer, speed sensor... The question isn't, "what sensors does a robot have", but rather, "what sensors does the engineer think that the robot should have?"
