During long-term use, car starters may have various faults, involving car starter bendix, direct drive starter, SVC PWR AWN and car starter replacement. Mastering the correct fault diagnosis and repair points can quickly solve the problem and ensure the normal operation of the car.
When the car starts abnormally, such as slow start or failure to start, first check the power system related to SVC PWR AWN. Make sure the battery is fully charged and the connection line is firm and not loose. Use a multimeter to measure the battery voltage, which should be around 12V under normal circumstances (different models may vary slightly). If the voltage is too low, it may be due to battery aging or charging system failure, which requires further investigation. At the same time, check the control module of SVC PWR AWN to see if there is a fault code displayed. If so, repair it according to the fault code prompt.
If the power system is normal, then check the direct drive starter. When starting, listen for the sound of the motor turning. If the motor does not turn, it may be a fault in the motor itself, such as coil burnout, brush wear, etc. For direct drive starter, due to its relatively simple structure, you can directly check whether the wiring of the motor is loose and whether the mechanical parts inside the motor are stuck. If the motor rotates but the engine does not start, there may be a problem with the car starter bendix.
A common fault of car starter bendix is slippage, that is, the one-way clutch cannot transmit power normally. The gear wear of the one-way clutch can be checked by disassembly. If the wear is serious, a new car starter bendix needs to be replaced. When installing a new one-way clutch, make sure it is installed correctly and the gap is appropriate, otherwise it will affect the starting effect.
When it is determined that a part cannot be repaired, such as the direct drive starter is seriously damaged or the car starter bendix cannot work properly, a car starter replacement is required. When choosing replacement parts, strictly follow the adaptation requirements of the vehicle model and choose reliable products. After replacement, a start test should be performed to ensure that the new starter works properly and all performance indicators meet the requirements. At the same time, after the repair, the car starting system should be fully checked to ensure that the power regulation of the SVC PWR AWN is normal, the direct drive starter runs smoothly, and the car starter bendix engages and disengages smoothly to ensure that the car starting system returns to a good working condition.
