Solution

1. Preparation

Gather tools and components required for the repair.
Disconnect the vehicle battery to ensure safety during the repair process.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, replacement fuses, and wiring repair tools.

2. Battery and Charging System Check

Use a multimeter to measure battery voltage; it should be between 12.4V and 12.6V for a fully charged battery.
Inspect battery terminals for corrosion or looseness, and clean or tighten as necessary.
If the battery is faulty, replace it with a new one that meets OEM specifications.

3. Fuse Inspection and Replacement

Locate the fuse box (refer to the owner's manual for location).
Identify fuses related to the safety systems and visually inspect them.
Replace any blown fuses with the correct amperage rating.

4. Wiring and Connector Inspection

Inspect all wiring related to safety systems for signs of wear, fraying, or damage.
Ensure all connectors are seated properly and free of corrosion. Clean and reconnect as needed.

5. Sensor Check

Visually inspect safety system sensors (such as front-facing cameras or radar sensors).
Clean any dirt or debris obstructing the sensors.
If a sensor is damaged, replace it according to the service manual instructions.
