Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper cables.
Ensure the car is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Check

Sub-steps:
1. Disconnect the negative terminal of the battery using a socket set.
2. Clean any corrosion on the terminals with a wire brush.
3. Reconnect the battery terminals securely.
Tools Required: Socket set, wire brush.

3. Jump-Start the Vehicle

Sub-steps:
1. Connect jumper cables: red to the positive terminal of the dead battery and the other end to the donor vehicle's positive terminal.
2. Connect the black cable to the negative terminal of the donor vehicle.
3. Attach the other end of the black cable to an unpainted metal surface on the engine block of the G70 (this acts as a ground).
4. Start the donor vehicle and then attempt to start the G70.
Safety Warnings: Ensure both vehicles are turned off before connecting cables; keep sparks away from batteries.

4. Replace Starter Motor (if necessary)

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove any components obstructing access to the starter motor (e.g., intake duct).
3. Unbolt the starter motor from its mounting bracket.
4. Disconnect the electrical connections from the starter.
5. Install the new starter by reversing the removal steps.
Tools Required: Socket set, wrenches.
