【Fault description】
    The engine is worn out or when the brake is braked.
    【Inspection process】
    First with Honda dedicated detector HDS engine control unit for testing, no fault code. Read the data stream is not found abnormal, and the engine in idle conditions running smoothly. In order to determine the fault, do the following routine inspection: the throttle body and the idle valve was cleaned after the test, the fault remains the same. The spark plug of this car has also been checked and no abnormality has been found; then the oil pressure of the fuel system is detected by the oil pressure gauge (normal fuel pressure is 270kPa ~ 320kPa). The failure only in the rapid acceleration or braking when the time, according to experience this failure out of the ignition system is more likely. As the car's high-voltage line and ignition coil is one of the occasional accident probability is not high, so the replacement of the throttle body and idle motor, but the fault remains the same. Check the line, found in the throttle next to the inlet on the ground line of virtual access.
    【Fault Analysis】
    It is known from the maintenance data that the ground wire here is the ground of the ignition control module. Due to poor connection here, when the vehicle in the rapid acceleration and braking when the engine before and after the large shaking, resulting in ignition control module ground contact bad and off the fire, resulting in engine jitter.
    【Maintenance】
    Will be re-processing of the wire re-processing after the test, troubleshooting.
