The VT55 triggers all newly mounted TPMS sensors and turns the warning light off. It decodes the sensor data and ensures that the correct tire pressure monitoring sensor is being read and isn?t a radio frequency transmission from a key fob or other sensor. The process allows the user to display the data on screen but also to transfer it to a PC and print out results outlining which sensor is faulty and why.The ATEQ VT55 OBDII TPMS Diagnostic Tool displays sensor ID, pressure, battery status, temperature, accelerometer and more.
Cars in normal operation, the automobile electronic control system signal input and output (voltage or current) will change regularly with a certain range; electronic control circuit when the obd2 scan tool is abnormal and beyond the normal range of variation, and this anomaly does not disappear at a certain time (three continuous stroke) within, ECU determines that a failure of this part, the fault indicator lamp is lit while the fault monitor in the form of code stored in the internal RAM ( RandomAccessMemory: Random Access Memory), is the fault code stored in the maintenance can be read by the fault indicator lights or OBD2 scanner.
If the fault is no longer present, the monitor after three consecutive times to the relevant signal is not received, the command displays the fault light goes out. Fault indicator light turns off after engine warm cycle about 40 times, the fault code will automatically be removed from memory.
