At the same time, the STOP inscription is lit in red on the dashboard. First of all, computer diagnostics were carried out using the Launch x431 scanner, Thinkdiag, Kingbolen, Diagzone, Ediag, Thinkcar, Mucar, Launch, Ediag, Kingbolen, Diagzone and the error p1644 speed limit switch was detected. And also the error p1614. This switch is in the form of a button under the gas pedal, when the gas pedal is fully pressed until it clicks, the limit switch is triggered, which turns off the included speed limiter. The installation of a resistor instead of a button is the so-called cheat, after which the error was successfully removed and the car was sent for testing. The behavior of the car in motion has changed.
