We start troubleshooting by checking the fuse "EF3" 30 A..
... located in the mounting block of the engine compartment.
The failure of the "EF3" fuse can be caused by a malfunction not only in the starter control circuit, but also in the power supply circuits of the heater fan and power windows.
If the "EF3" fuse is intact, we proceed to check the starter's performance.
To check, turn off the ignition..
... and connect the control output of the traction relay and the tip of the wire coming from the "positive" battery terminal with a piece of insulated wire.
When carrying out this operation, care must be taken, since sparking is possible in the contact zone of the leads with a piece of wire. Do not short the wire to ground while connecting the leads!
If at the same time the crankshaft rotates, then the starter is working, and the cause of the malfunction is a violation in its switching circuit. Otherwise, the starter or its traction relay is faulty.
If it is not possible to eliminate the malfunction in the switching circuit of a working starter, then, if necessary, in this way (turn on the ignition and connect the leads) you can start the engine and drive on your own to the place of repair.
