  • Ensure the vehicle is parked on a flat surface and is in "Park" mode.
  • Disconnect the 12V battery to prevent electrical hazards.
2. Inspect Engine Components
  • Tools Required: Socket set, torque wrench, multimeter.
  • Visually examine the electric motor mounts and fasteners for any signs of looseness.
  • Use the torque wrench to tighten any loose bolts to the manufacturer's specifications (refer to service manual for specific torque values).
3. Check Electrical Connections
  • Tools Required: Multimeter.
  • Inspect all electrical connections to the electric motor and battery for corrosion or looseness.
  • Test the voltage at the motor terminals using the multimeter to ensure it is within the specified range.
4. Inspect Battery and Cooling System
  • Tools Required: Torque wrench, coolant pressure tester.
  • Check the battery coolant level and inspect for leaks in the cooling system.
  • Ensure all hoses are tightly connected and clamps are secure.
  • Refill coolant if necessary and tighten all connections.
5. Reassemble and Test
  • Reconnect the 12V battery.
