Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, battery load tester, fuse puller.
Ensure the vehicle is parked on a level surface and the ignition is off. Disconnect the negative battery terminal to prevent any electrical shorts during inspection.

2. Replace Blown Fuses

Sub-steps:
1. Identify and remove any blown fuses using a fuse puller.
2. Replace with new fuses of the same amperage rating.
3. Reconnect the negative battery terminal after replacing fuses.

3. Clean Battery Terminals

Sub-steps:
1. Disconnect the negative terminal, then the positive terminal from the battery.
2. Clean the terminals and battery posts with a wire brush to remove corrosion.
3. Reconnect the positive terminal first, followed by the negative terminal.

4. Repair Ground Connections

Sub-steps:
1. Locate all ground points in the vehicle, often found near the battery and in various chassis locations.
2. Clean any corrosion or dirt from the ground points with a wire brush.
3. Tighten the ground connections to the specified torque (check manufacturer specifications).

5. Replace Battery (if necessary)

Sub-steps:
1. If the battery fails the load test or is below 12.4V, remove the battery by disconnecting the terminals.
2. Replace with a new battery that meets OEM specifications.
3. Reconnect terminals, ensuring they are secure.
