Solution

1. Preparation

Tools Required: Socket set, brake cleaner, multimeter, OBD-II scanner
Ensure the vehicle is parked on a level surface and the engine is turned off.
Allow the vehicle to cool down if it has been running.

2. Brake Inspection and Repair

Sub-steps:
1. Remove the wheel on the affected side using a lug wrench.
2. Inspect the brake pads and rotors for excessive wear. Replace if thickness is below manufacturer specifications.
3. Check the caliper for proper operation and any signs of sticking.
4. Clean the brake components using brake cleaner to remove dust and debris.
5. Reassemble the wheel and torque the lug nuts to the manufacturer’s specifications.

3. Electrical Inspection and Repair

Sub-steps:
1. Disconnect the battery to prevent electrical shock.
2. Inspect all electrical connections for corrosion or damage.
3. Use a multimeter to check the voltage at the battery terminals and ensure they are within normal operating range (typically around 12.6 volts).
4. Replace any damaged cables or connectors found during inspection.

4. Motor and Drivetrain Inspection

Sub-steps:
1. Check for fluid leaks in the motor compartment. Clean up any leaks and identify the source.
2. Inspect the drive belts for signs of wear or burning. Replace if frayed or cracked.
3. Test the electric motor for proper operation by using the OBD-II scanner to check for fault codes.
