Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical systems.
Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set, wire strippers/crimpers.

2. Inspect Battery and Connections

Remove the battery terminal covers.
Check for corrosion and clean terminals with a wire brush if needed.
Tighten any loose connections to ensure a secure fit.

3. Replace Blown Fuses

Locate the fuse box as per the vehicle manual.
Identify and remove any blown fuses using a fuse puller.
Replace with new fuses of the same amperage rating.

4. Repair or Replace Damaged Wiring

Inspect the wiring harnesses visually and by touch for any signs of wear or damage.
If damage is found, use wire strippers to remove insulation, splice in new wire, and crimp connections securely.
Use electrical tape or heat shrink tubing to insulate the repair.

5. Test Electrical Components

Reconnect the battery and use the OBD-II scanner to clear any fault codes.
Check electrical accessories (windows, locks, etc.) for proper function.
Monitor the infotainment system and charging performance to ensure all issues are resolved.
