Checking without removing from the vehicle
1. If the starter motor does not turn at all when you turn the key, make sure the selector lever is in the Park or Neutral position (on cars with automatic transmission) or press the clutch pedal.
2. Make sure the battery is charged, check the cleanliness and reliability of the cable fastening on the battery and on the starter solenoid relay.
3. If the starter motor turns on when the key is turned, but the crankshaft does not turn, then the cause is slipping of the starter overrunning clutch. In this case, the starter assembly should be replaced.
4. If the starter motor does not rotate when the key is turned, but the traction relay clicks, then the traction relay contacts, battery and starter motor are faulty (or the crankshaft turns with difficulty).
5. If, when the starter is turned on, the click emitted by the relay anchor is not heard, then the reasons for the failure may be a faulty battery or a burnt-out fuse (the circuit is open), malfunction of the auxiliary starter relay or the traction relay itself.
6. To check the traction relay, short-circuit the (+) battery terminal and the terminal for the wire from the ignition key with a jumper (located on the traction relay).
7. If the starter motor starts, the traction relay is OK and the ignition switch, auxiliary starter relay, or wiring are faulty.
8. If the starter motor still does not start, remove the starter assembly with the traction relay for inspection and repair.

9. If the starter turns the crankshaft, but at a very low speed, then first check the battery charge level and the reliability and integrity of the connections. The starter will also turn the engine at a low speed if the crankshaft rotates with difficulty or the engine is filled with oil with too high viscosity.
10. Warm up the engine, then disconnect the coil high-tension wire from the distributor cap and connect it to ground on the engine.
11. Connect the positive terminal of the voltmeter to the positive pole of the battery and the negative terminal to the negative pole.
12. Turn on the starter and read the steady-state voltmeter reading. The starter engagement time should not exceed 15 seconds. The battery voltage at normal crankshaft speed should be 9 V or slightly higher.
13. If the battery voltage is 9 V or slightly above 9 V and the crankshaft speed is low, the starter motor is faulty.
14. If the voltage is less than 9 V and the crankshaft rotation speed is low, then the probable causes are burning of the traction relay contacts, a malfunction of the starter motor, self-discharge of the battery, or poor condition of the contacts.
Removal and installation
1. Disconnect the battery from ground.
2. Remove the battery from the engine compartment.
3. Disconnect and remove the cruise control unit from the engine compartment.
4. Disconnect the connectors from the starter and traction relay.
5. Loosen the starter mounting bolts (the arrow indicates the upper starter bolt).
6. Remove the bracket from the top of the starter assembly with the solenoid relay.
Attention! First, partially unscrew one or two bracket bolts, then move the starter with the traction relay down, and then unscrew the remaining bolts.
7. Installation is carried out in reverse order.
