Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-step 1: Inspect the battery terminals for corrosion. If present, clean with a mixture of baking soda and water.
Sub-step 2: Tighten any loose connections using a socket set.
Sub-step 3: If the battery voltage is low, replace it. Remove the negative (-) cable first, followed by the positive (+) cable.
Sub-step 4: Install the new battery by connecting the positive (+) cable first, then the negative (-) cable.

3. Starter Motor Testing and Replacement

Sub-step 1: If the battery is good and connections are tight, remove the starter motor. This usually requires removing the protective cover and disconnecting the wiring harness.
Sub-step 2: Test the starter by applying direct voltage to the terminals. If it does not engage, replace the starter motor.
Sub-step 3: Install the new starter motor, ensuring all connections are secure and torqued to the manufacturer specifications.

4. Ignition Switch Inspection (if necessary)

Sub-step 1: If the starter motor checks out, test the ignition switch for continuity using a multimeter.
Sub-step 2: If faulty, replace the ignition switch by removing the steering column covers and disconnecting the switch harness.
