We start troubleshooting by checking the 30 A "EF3" fuse..
…located in the engine compartment mounting block.
Failure of the "EF3" fuse may be caused by a malfunction not only in the starter control circuit, but also in the power supply circuits of the heater fan and electric windows.
If the fuse "EF3" is intact, we proceed to check the functionality of the starter.
To check, turn off the ignition..
…and we connect the control terminal of the traction relay and the tip of the wire coming from the positive terminal of the battery with a piece of insulated wire.
When performing this operation, it is necessary to be careful, since sparking is possible in the area of contact of the terminals with the wire section. Do not short-circuit the wire to "ground" when connecting the terminals!
If the crankshaft turns, the starter is in good condition and the cause of the malfunction is a fault in its switching circuit. Otherwise, the starter or its traction relay is faulty.
If it is not possible to eliminate the fault in the circuit of a serviceable starter, then, if necessary, in this way (turn on the ignition and connect the terminals) you can start the engine and drive to the repair site under your own power.
