The MA connector (junction box under the radiator grille on the left) and from the MAĬonnector to the CLF connector (junction box in the center of theĭashboard). Check dataĬhannel J 1587 / J 1708 between the engine block and Is present, the engine block enters idle mode. Is SAE J 1587 / J 1708, the error is in the The signal of the position of the accelerator pedal is incorrect or missing, the sensor on the accelerator pedal is faulty, the data channel Check the integrity of the data channel wiring. Įrror data channel data SAE J 1708, an error in the vehicleĬontrol unit ( VECU ).

If FMI 9 is present, the engine speed does not exceed 1700 rpm. Transmitted via the data channel SAE J 1708. There is no or incorrect speed signal transmitted via the dataĬhannel SAE J 1939, the speed sensor is faulty, the dataĬhannel SAE J 1939 is faulty, the vehicle control unit If FMI 11 is present, the engine speed does Short circuit to high voltage or high voltageįaulty speed sensor, error of data channel data SAE J 1708, error in the vehicle control unit ( VECU ). Not turn on starting in cold weather is difficult. Open circuit, fuse for heating relay fuse blown, wire break between engine control unit and relay, open relay power wire. The air heater isĬonstantly activated, as a result of overheating, the heating spiral can be destroyed and parts of the spiral can get into the intake manifold of the internal combustion engineĪnd into the valve mechanism. Relay K48 closes to ground, the preheating relay K48 is faulty.

The code is only active if the ignition key is in the preheating position (between the ignition switch position and theĮngine start position) The wire between the engine control unit from terminal EB31 and Starting ICE in cold weather is difficult. The wire between the engine control unit from contact EB 31Īnd relay K 48 closes to a constant plus, relay K48 isįaulty. Maximum speed, which causes high fuel consumption. Wiring is damaged or the insulation of the wires is poor, the sensor on the fan is faulty, the fan is faulty. The ICE unit detected excess pulses in the fan speed signal, the The fan rotates at maximum speed, which causes high fuel consumption.

The voltage at the contact of the engine block EA 6 is higher than 65% of the battery voltage, a short to positive, a break in the power or ground wire, a sensor
