Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake cleaner, safety goggles, gloves.
Ensure the vehicle is parked on a level surface with the engine off and cool.

2. Addressing Brake Issues

Lift the Vehicle: Use a jack and jack stands to safely lift the vehicle and secure it.
Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect Brake Components:
- Check brake pads for thickness; replace if worn down to less than 3mm.
- Inspect rotors for scoring or warping; machine or replace as necessary.
Reassemble: Reinstall the wheel and lug nuts, ensuring they are torqued to the manufacturer specifications.

3. Repair Electrical Wiring

Identify Damaged Wiring: Locate any damaged wiring or connectors identified during the diagnostic steps.
Repair or Replace Wires:
- Cut out damaged sections and splice in new wire of the same gauge and type.
- Use heat shrink tubing or electrical tape to insulate connections.
Reconnect and Secure: Ensure all connections are secure and that wiring is routed away from hot or moving components.

4. Battery and Charging System Check

Test Battery Voltage: Use a multimeter to measure the battery voltage; it should read between 12.4 to 12.7 volts at rest.
Check Alternator Output: With the engine running, check that the alternator output is between 13.7 to 14.7 volts.
Replace Components as Necessary: If battery or alternator is faulty, replace with OEM specifications.
