High voltage or short circuit to high voltage circuit

Abnormal frequency, pulse width, or period

High voltage or short circuit to high voltage. The wire between the engine control unit (ECU) from terminal EB31 to relay K48 is shorted to positive. Relay K48 is faulty. Starting the engine in cold weather is difficult. The code is only active when the ignition key is in the preheat position (between the ignition on and the engine start position).

Low voltage or short circuit to a lower voltage circuit. The wire between the engine control unit (ECU) from terminal EB31 to relay K48 is shorted to ground. The K48 preheater relay is faulty. The air heater is constantly activated, and overheating can cause the heater coil to break, causing parts of the coil to enter the engine intake manifold and valve train.

Current below normal or open circuit. Open circuit, blown heater relay fuse, open wire between engine control unit and relay, open wire to relay power supply. Heater does not engage, difficult to start in cold weather.

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

Irregular, erratic or incorrect data

High voltage or short circuit to high voltage circuit

Current below normal or open circuit

Faulty device or component

Abnormal update rate. Faulty speed sensor, SAE J1708 data link error, vehicle control unit (VECU) error. If FMI 11 is present, engine speed does not exceed 1700 rpm. Check data link wiring for integrity.

The speed signal transmitted via the SAE J1939 data link is missing or incorrect. The speed sensor is faulty, the SAE J1939 data link is faulty, or the vehicle control unit (VECU) is faulty. The speed signal is transmitted via the SAE J1708 data link. If FMI 9 is present, the engine speed does not exceed 1700 rpm. Check the integrity of the data link wiring.

Abnormal update rate. SAE J1708 data link error, vehicle control unit (VECU) error. Check data link wiring for integrity.

Abnormal update rate. Accelerator pedal position signal is incorrect or missing, accelerator pedal sensor is faulty, SAE J1587/J1708 data link is faulty, vehicle control unit (VECU) error. If FMI 11 is present, the engine control unit enters idle mode. Check the J1587/J1708 data link between the engine control unit and the MA connector (junction box under the left radiator grille) and from the MA connector to the CLF connector (junction box in the center of the instrument panel). If the wiring is normal, replace the accelerator pedal.

The pedal position signal is not transmitted via the SAE J1939 data link. The accelerator pedal sensor is faulty, the SAE J1939 data link is faulty, or there is an error in the vehicle control unit. If FMI 9 is present, the engine goes into idle mode. Check the integrity of the data link and replace the accelerator pedal.

The data is valid but below the normal operating range. For D6B, D7C, D10B, and D12C engines: Fuel pressure is below normal. Clogged fuel filter, fuel leak, air leak, bypass valve opening at low pressure, mechanical pump not pumping well, or sensor faulty. Check the fuel pressure with a pressure gauge. For D16B engines: Fuel pressure is above normal (over 700 kPa). Clogged fuel filter, bypass valve not opening.

High voltage or short circuit to high voltage circuit. Voltage at engine block terminal EA27 is above 4.95 V. Short circuit to power supply or signal wire. Possibly faulty sensor.

The voltage at the EA27 contact of the engine block is below 0.08 V. There is a break in the power, signal, or ground wires of the fuel pressure sensor. The sensor may be faulty.

Current below normal or open circuit

The mechanical system isn't responding correctly. The fuel pressure is below normal. Clogged fuel filter, fuel leak, air leak, bypass valve opening at low pressure, mechanical pump not pumping properly, sensor faulty. Check the fuel pressure with a pressure gauge.

High voltage or short circuit in the high-voltage circuit. Voltage at the EB6 engine block terminal exceeds 91% of battery voltage. Short circuit to power or signal wire, or open signal wire. The indicator may be faulty.

Low voltage or short circuit to a lower voltage circuit. Voltage at the EB6 engine block terminal is below 5% of battery voltage. Short circuit to negative or to the signal wire. The indicator may be faulty.

Current below normal or open circuit

Special instructions. This code indicates that the electric fuel pump is activated. It is not a fault code.
