Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and safety gloves.
Ensure the vehicle is parked on a level surface and set the parking brake.

2. Battery Inspection

Sub-step 1: Disconnect the negative (-) terminal of the battery to prevent short circuits.
Sub-step 2: Inspect the battery terminals for corrosion. Clean them with a wire brush and apply battery terminal protector.
Sub-step 3: Reconnect the battery terminals securely, ensuring they are tight.

3. Starter Motor Examination

Sub-step 1: Locate the starter motor (usually near the base of the engine).
Sub-step 2: Disconnect the wiring harness and the power cable from the starter motor.
Sub-step 3: Use a multimeter to test for power at the starter motor terminals when the ignition key is turned to the start position.
Sub-step 4: If no power is detected, trace wiring back to the ignition switch and check for continuity.

4. Replace Starter Motor (if faulty)

Sub-step 1: Remove any components obstructing access to the starter motor.
Sub-step 2: Unbolt the starter motor from its mounting using the socket set.
Sub-step 3: Install the new starter motor, ensuring proper alignment.
Sub-step 4: Reconnect the power cable and wiring harness, ensuring a tight fit.
Sub-step 5: Torque the mounting bolts to manufacturer specifications (typically around 20 Nm, check specific values).

5. Final Checks

Reconnect the negative terminal of the battery.
Start the vehicle to confirm the repair.
