During operation, electronic devices monitor the correct functioning of the system. When

any discrepancies occur, an error code is issued on the computer corresponding.

Depending on the severity of the anomaly, electronic devices can, in some situations, go into

partial mode.

The code indicates an anomaly that has been detected by one of the electronic components on the tractor. This code is displayed

into the memory of the module that issued the code.

The code is displayed in the following form: Id75C0h

- Id means identification

- 75C0 means error code

- h stands for hexadecimal (error code encoding).

Cause

These items are listed in the CCN Component List.

For each of them it follows:

- Check the connectors and harness integrity between each component.

- Check for short circuit or open circuit.

- Check, if required, the resistance of the components.

- Check, if necessary, the adjustment of the components.

- Check energy sources (fuses, power supply and earth).

- Check the operating conditions of the component (pressure, temperature, mechanical friction, etc.).

- Check CAN networks

- Check, if required, compatibility of software versions, parameters and reference.

- If necessary, replace the component.

These control values are indicated on the test and measurement cards.

Note: Features of transmission modules TR1 (A57-1), TR2 (A57-2), TR3 (A57-3):

- Sound signal: The sound signal is triggered when it is necessary to stop the tractor.

- Requested to restart "ISC": In some cases, it is necessary to restart the inverter. For this,

proceed as follows: With the engine running, press the clutch pedal.

the text is only in Russian, if you wish, you can translate the desired error code.

CLAAS special machinery is very reliable and rarely fails. But even she sometimes breaks down. It can be a very unpleasant situation when the CLAAS engine stalls and does not want to start. At the same time, a message with a corresponding description of the error code is illuminated on the instrument panel display. But there are also exceptions when errors are not highlighted. The specialists of our company have accumulated solid experience in the diagnosis and repair of the described faults. There are two radically different options for "not starting" the engine:

• When turning the key in the ignition lock, the starter turns the excavator engine
• The starter does not turn on and does not turn the engine

I will try to tell you in more detail about each of the options for equipment malfunction.

CLAAS starter does not turn

If the control system of the above equipment, when turning the ignition key to start, does not turn on the starter, then the cause of the breakdown lies in the electrical equipment or electronic systems of the truck. The reasons may be as follows:

• Defective relay and fuse box
• Lack of contacts in the wiring connectors
• Malfunction of the main relay of the truck
• Failure of the ignition lock Failure of the starter
• Open or short circuit of the CAN bus
• Lack of "mass"
• Lack of supply voltage at the engine control unit
• Open or short circuit wiring harness
• Malfunction of the starter solenoid relay
• Failure of the ignition switch
• Failure of the engine control unit

Starter turns - will not start

If the starter of the described technique turns when the key is turned in the ignition lock, but the motor does not show any signs. The cause of the malfunction may lie both in the electrical equipment of the car and in the mechanics. Auto electrics malfunctions can be as described above, except for malfunctions associated with the starter and its circuits, plus the following reasons:

• Malfunction of the high pressure fuel pump (TNVD)
• Mechanical engine failure
• "Airing" the fuel equipment
• Immobilizer malfunction
• Lack of diesel fuel in the tank
• Clogged fuel filter
• Faulty chip in the key
• Clogged fuel lines
• Check valve breakage
• Mechanical malfunctions of injectors
