- a) Check the battery charge level, as well as the condition and reliability of the wires on the battery terminals and the starter traction relay;
- b) Check the condition of the battery wires (see Section Checking the condition and replacing the battery wires). Replace defective components;
- c) Check Battery Status (see Section Checking the condition and replacing the battery). If necessary, replace it with a new one;
- d) Check the condition of the starter wiring and terminal connections (see wiring diagrams in Chapter Onboard electrical equipment);
- e) Check up reliability of a tightening of bolts of fastening of a starter;
2. If the starter does not start to rotate when the ignition key is turned to the START position, check the battery power supply to the traction relay when the ignition is off. The positive battery terminal must have battery voltage.
3. Use a voltmeter to probe the S terminal on the rear side of the traction relay connector, and when the key is turned to the START position, voltage should be present on the terminal. This test confirms that power is being supplied to the starter from the ignition switch. If there is no voltage, check the condition of the corresponding fuses in the mounting block in the engine compartment of the car (see chapter Onboard electrical equipment). In the event of failure of the inserts, the cause of the overload must be found and eliminated. Also check the corresponding fuses in the mounting block located in the passenger compartment (see chapter Onboard electrical equipment). If the fuses and fuses are in order, check the condition of the starter blocking relay and its wiring circuit (see chapter Onboard electrical equipment).
4. If there are no signs of functioning of the starting system, check the condition of the sensor-switch of permission to start / open the starter circuit (see chapter Transmission or Clutch and drive shafts). Make sure the selector lever is in position "R" or "N"/check that the clutch pedal is fully depressed.
5. On a vehicle equipped with an anti-theft alarm, check the circuit and the system control module for signs of a short circuit or component damage.
6. If the voltage is supplied to the starter properly, but its activation does not occur, therefore, the traction relay is out of order (the possibility of engine jamming is also possible - check by turning it manually by the crankshaft pulley bolt).
7. Remove the starter from the engine (see Section Removal and installation of a starter) and clamp the assembly in a soft-jawed vise mounted on a sturdy workbench. Connect the negative terminal with a jumper wire (-) batteries with assembly case. With a second jumper wire, connect the positive battery terminal to the terminal "IN " starter. Connect the starter switch and apply power to the S terminal of the traction relay (no more than 10 seconds). Make sure that the traction relay plunger moves forward, displacing the drive lever and overrunning clutch accordingly, and the extended starter drive gear begins to rotate properly. If the gear extends but does not rotate, then the electric motor is faulty. If the plunger does not extend despite the relay clicking properly, a defect in any of the assembly components may be the cause of the failure. On a good starter, the drive gear should extend and rotate when power is applied.
