کدهای خطای MID 128

Irregular, erratic, or incorrect data. Incorrect response from the immobilizer unit. The immobilizer unit code does not match the engine unit code. The engine unit or immobilizer unit is incorrectly programmed.

Defective device or component. No response from the immobilizer unit. Broken wiring between the engine block and the immobilizer unit, or a faulty immobilizer unit.

Undetectable malfunction. Calibration factor "K" is not transmitted via the SAE J1708 data link. Data link error or error in the VECU vehicle control unit.

Abnormal update rate. Vehicle mileage information is not being transmitted via the SAE J1708/J1587 data link. Data link or instrument cluster malfunction.

Irregular, erratic or incorrect data

Abnormal update rate. Message lost on SAE J1708 data link. Data link between engine control module and vehicle control unit (VECU) broken.

Abnormal update rate. Message lost on SAE J1708 data link. Data link between engine control module and vehicle control unit (VECU) broken.

The data is reliable but is above the normal operating range.

High voltage or short circuit to high voltage circuit. Voltage at engine block terminal EA21 is above 5.5 V. Back pressure sensor or wiring is faulty.

The current is below normal or there is an open circuit. The voltage at the EA21 contact of the engine block from the backpressure sensor is above 4.95 V. There is a short circuit to the power or signal wire. There is an open circuit in the signal, power, or ground wire. The sensor may be faulty.

The mechanical system does not respond correctly

Abnormal frequency, pulse width, or period

Abnormal refresh rate

Faulty device or component

Special instructions

The data is reliable but is above the normal operating range.

Low voltage or short circuit to lower voltage

Current below normal or open circuit

Too much fluctuation

The wire between the injectors and contacts EA12 or EA24 is shorted to the power wire. Three of the six injectors are operating.

High voltage or short circuit to high voltage. Short circuit of one of the injector circuit wires to the engine block contacts (EA11, 22, 23, 34, 35, 36) to a wire with a higher voltage. Short circuit between injector wires. 5 or 3 cylinders not firing.

One of the injector circuit wires is shorted to ground before the engine block contacts (EA11, 22, 23, 34, 35, 36) or contacts (EA 12, 24). Three of the six injectors are working.

Current below normal or open circuit. Open circuit in the injector circuit. If three fault codes are displayed for one row of injectors, there is an open circuit between the injectors and the engine block contacts EA12 or EA24. If one fault code is displayed, there is an open circuit between the corresponding injector and one of the engine block contacts (EA11, 22, 23, 34, 35, 36). 3 or 5 cylinders are operating.

The mechanical system isn't responding correctly. The cylinder balance data is high. A faulty injector, low compression in the corresponding cylinder, or uneven engine load from the power takeoff. The engine runs unevenly, power is reduced, and abnormal noise is possible.

Too much fluctuation
