Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Resolve Identified Issues

If error codes indicate a specific sensor failure:
1. Remove the faulty sensor (e.g., oxygen sensor, ABS sensor) by disconnecting the electrical connector and unscrewing it.
2. Install the new sensor, ensuring it is securely fastened and the connector is properly attached.
If a blown fuse is found:
1. Identify the fuse related to the warning light from the owner's manual.
2. Remove the blown fuse using a fuse puller and replace it with a new fuse of the same amperage.
If fluid levels are low:
1. Top off the required fluids (engine oil, coolant, brake fluid) with the manufacturer-recommended types.
If wiring issues are discovered:
1. Repair or replace damaged wires and connectors ensuring solid connections.

3. Reconnect Battery

After repairs, reconnect the vehicle battery and ensure all connections are tight.
