Solution

1. Preparation

Gather tools and materials. Ensure the vehicle is in park and the ignition is off.
Tools Required: Multimeter, OBD-II scanner, socket set, torque wrench, jumper wire.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal.
2. Clean any corrosion from the terminals using a wire brush or battery cleaner.
3. Reattach the battery terminals securely and check for a tight fit.

3. Starter Motor Check

Sub-steps:
1. Locate the starter motor beneath the vehicle, typically near the transmission.
2. Disconnect the electrical connector from the starter.
3. Use a jumper wire to connect the positive terminal of the battery directly to the starter terminal to test if it engages.
4. If the starter does not engage, replace it.

4. Engine Oil Inspection

Sub-steps:
1. Remove the oil dipstick and check the oil level.
2. If the oil is low, add the appropriate engine oil as per the manufacturer’s specifications.
3. If the oil is dirty or contaminated, consider performing an oil change.

5. Reassembly and Final Checks

Sub-steps:
1. Reconnect all components and ensure everything is securely fastened.
2. Reconnect the battery terminals, starting with the positive terminal.
3. Start the engine and listen for the ticking noise.
