Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection and Replacement

Check Battery Condition
- Use a multimeter to measure the battery voltage.
- If the voltage is below 12.4V, proceed to jump-start the vehicle or replace the battery.
Clean Battery Terminals
- Remove the battery terminals (negative first).
- Clean any corrosion using a wire brush or terminal cleaner.
- Reconnect the terminals securely (positive first).

3. Starter Motor Inspection

Remove Starter Motor
- Locate the starter motor (usually near the transmission).
- Disconnect the wiring harness and the battery cable from the starter.
- Unbolt the starter motor using the appropriate socket size and remove it.
Test Starter Motor
- Bench test the starter motor using jumper cables to see if it engages.
- If it does not engage, replace the starter motor.

4. Reassemble and Test

Reinstall Starter Motor
- Position the starter motor back into place and secure it with bolts.
- Reconnect the wiring harness and battery cable to the starter.
Reconnect Battery
- Reconnect the negative battery terminal last.
Start the Vehicle
- Turn the key to the ignition position and check if the vehicle starts.
