Fault 1
    A Chrysler 300C3.5L sedan, equipped with the Mercedes-Benz 722.6 series of 5-speed automatic control automatic transmission, the user reflects the car when the automatic transmission failure warning lights lit, while the transmission into the emergency protection mode.
    Connect the fault diagnosis device to detect the transmission control system, the device prompts "input and output signal is not synchronized." The test process uses the fault diagnostic apparatus to read the data stream and find that the N1, N2 signals are not synchronized. Under normal circumstances, N2 in the 2 block and 2 block above the gear and N1 should be the same value, but the car's data is not the same, N2 shows 0. Disassembly control valve body found, N2 sensor slightly bent. Because the sensor can not be replaced separately, it can only replace the valve body assembly.
    After troubleshooting the valve body assembly, troubleshooting.
    Failure 2
    A Chrysler 300C sedan, ESP fault warning light lit.
    Connect the fault diagnosis device for testing, the device prompts "brake thrust switch failure". Check the line did not find the problem, then replace the brake light switch. After connecting the fault diagnosis device to continue to detect, the original fault code still exists. This makes us feel a bit puzzled, the brake system is so a switch! Check the line no problem, how to replace the switch is not OK? After access to relevant information, that the car in the vacuum booster with a thrust switch.
    Replace the switch after troubleshooting.
