Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Battery Inspection

Tools Required: Multimeter
Check the battery voltage. It should be above 12.6 volts for a healthy battery.
If the voltage is low, charge the battery or replace it if it fails to hold a charge.

3. Electrical Connection Check

Tools Required: Socket set, wrench
Inspect battery terminals and cables for corrosion or looseness.
Clean terminals with a battery terminal cleaner if corroded.
Tighten any loose connections.

4. Engine Oil Check

Tools Required: Oil dipstick, funnel
Remove the oil dipstick, wipe it clean, and reinsert it to check the oil level.
If the oil is low, add the correct type of engine oil as specified in the owner’s manual.
Look for any signs of contamination in the oil.

5. Component Inspection

Tools Required: Socket set, torque wrench
If the ticking noise persists, inspect components such as the starter motor and serpentine belt.
Tighten or replace any loose or worn components as necessary.
