Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe and flat location.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Reconnect the battery terminal and check voltage with a multimeter.
2. If the voltage is low, jump-start the vehicle using jumper cables and a functioning vehicle.
3. If the vehicle starts, the battery may need replacement. Remove the negative terminal first, followed by the positive terminal.
4. Unbolt the battery hold-down bracket and carefully lift out the battery.
5. Replace with a new battery of the same type (Group Size: 94R recommended).
6. Reinstall the new battery, first connecting the positive terminal, followed by the negative terminal.

3. Starter Motor Inspection and Replacement

Sub-steps:
1. Locate the starter motor, typically positioned near the base of the engine.
2. Remove any necessary components obstructing access to the starter.
3. Disconnect the wiring harness and the battery cable from the starter.
4. Unbolt the starter from its mounting position.
5. Install the new starter motor, ensuring it is securely bolted in place.
6. Reconnect the wiring harness and the battery cable.

4. Key Fob Reprogramming (if applicable)

Sub-steps:
1. Sit in the driver’s seat with all doors closed.
2. Insert the key fob into the ignition slot.
3. Press the start/stop button without pressing the brake pedal for about 5 seconds.
4. This will reprogram the fob; observe if the vehicle starts afterward.
