Solution

1. Preparation

Gather tools: wrench set, multimeter, battery terminal cleaner, jumper cables.
Ensure the vehicle is in park (automatic) or neutral (manual) and that the parking brake is engaged.

2. Battery Inspection and Replacement

Check Battery Connections
- Disconnect the negative terminal first, then the positive terminal.
- Clean any corrosion using a battery terminal cleaner.
- Reconnect terminals securely (positive first, then negative).
Test and Replace Battery if Necessary
- If the battery voltage is below 12.4 volts, charge the battery or replace it if it does not hold a charge.
- Install the new battery, ensuring proper orientation of terminals.

3. Starter Motor and Solenoid Check

Access the Starter Motor
- Remove any covers or components obstructing access to the starter motor.
- Locate the starter motor mounted on the transmission.
Inspect Connections
- Check the wiring and connections to the starter motor and solenoid for damage or looseness.
- Tighten any loose connections.
Test Starter Functionality
- Use a multimeter to check for voltage at the starter solenoid when the ignition is turned on.
- If no voltage is present, trace back to the ignition switch and wiring.
Replace Starter Motor
- If the starter motor is faulty, disconnect the wiring and remove the mounting bolts.
- Install the new starter motor and reconnect all wiring securely.
