Diagnostics of malfunctions of systems of injection of diesel engines

The following prerequisites must be met before fault diagnosis can be used to detect faults: Error conditions during start-up are excluded. There must be fuel in the tank, the engine is mechanically sound, the battery is charged, the starter is turning at a sufficient speed, the electrical connection to ground (engine-gearbox-body) available. Read the contents of the fault code memory (at the service station).

Attention: If the fuel lines are released, they must first be cleaned with cleaning agents.
