Solution

1. Preparation

Tools Required: Safety gloves, safety glasses, OBD-II scanner, jack and jack stands, torque wrench, multimeter.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the vehicle battery to prevent any electrical issues while inspecting components.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel using a jack and socket set.
- Examine the brake pads for excessive wear; replace if thinner than 3mm.
- Check the rotors for scoring or warping; replace if damaged.
Replace Brake Pads:
- Remove the caliper bolts and slide the caliper off the rotor.
- Use a caliper tool to compress the piston back into the caliper.
- Install new brake pads and reassemble the caliper, tightening bolts to the manufacturer’s torque specifications (typically around 25-35 ft-lbs).
Reinstall Wheel: Place the wheel back on and lower the vehicle.

3. Electrical System Inspection

Check Wiring:
- Inspect high-voltage wiring for any signs of wear, burn marks, or damage.
- Use a multimeter to check for continuity in wiring harnesses.
Replace Damaged Wiring:
- If damaged, cut out the affected section of the wire and splice in new wiring, ensuring connections are secure and insulated.

4. Brake Fluid and Coolant Check

Inspect Brake Fluid:
- Remove the cap from the brake fluid reservoir and check the fluid level; fill to the recommended level using DOT 3 or DOT 4 brake fluid as specified by the manufacturer.
Check Coolant Level:
- Open the coolant reservoir and ensure it's filled to the appropriate level; top off if necessary with the recommended coolant type.
