Solution

1. Preparation

Gather tools: multimeter, socket set, screwdriver, OBD-II scanner.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.

2. Battery Inspection

Sub-step 1: Disconnect the negative terminal of the battery.
Sub-step 2: Clean any corrosion from the terminals using a wire brush.
Sub-step 3: Reconnect the terminals securely.
Sub-step 4: If the battery voltage is low, jump-start the vehicle using jumper cables.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor (typically under the engine near the transmission).
Sub-step 2: Disconnect the electrical connector from the starter.
Sub-step 3: Use a multimeter to check for voltage at the starter terminal when the key is turned to the start position.
Sub-step 4: If no voltage is present, trace the wiring back to the ignition switch.

4. Starter Replacement (if needed)

Sub-step 1: If the starter motor is faulty, remove the mounting bolts using a socket set.
Sub-step 2: Disconnect the positive battery terminal before removing the starter.
Sub-step 3: Remove the starter motor from its location.
Sub-step 4: Install the new starter motor in reverse order, ensuring all connections are secure.

5. Final Checks

Sub-step 1: Reconnect the battery terminal.
Sub-step 2: Test the ignition system to ensure proper operation.
