1. Preparation

Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the 12V battery to ensure safety during repairs.
Gather necessary tools and parts.

2. Tire and Brake Inspection

Remove the wheel covers or wheels as needed using a jack and jack stands.
Inspect tires for signs of uneven wear or damage; replace if necessary.
Check brake pads for wear; if they are worn down, replace them.
Ensure brake calipers are functioning correctly and not sticking; service or replace if needed.

3. Electrical System Check

Reconnect the 12V battery.
Use an OBD-II scanner to check for any fault codes related to the electric drive unit or battery system.
Inspect high-voltage cables for any abrasions or signs of overheating; replace damaged cables.

4. Motor and Component Inspection

Remove any covers or shields to access the electric motor.
Inspect the motor for signs of overheating, such as discoloration or burnt smells.
Check for loose connections or damaged components; repair or replace as necessary.
