Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and wrench set.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Battery Inspection

Inspect Battery Connections:
- Remove the battery terminals (negative first, then positive).
- Clean corrosion from the terminals and cable ends using a wire brush.
- Reattach terminals securely.
Test Battery Voltage:
- Use a multimeter to check voltage. If below 12.6 volts, charge or replace the battery.

3. Starter Relay and Motor

Test the Starter Relay:
- Locate the starter relay in the fuse box.
- Swap it with a similar relay to check functionality; if the clicking stops, replace the relay.
Check the Starter Motor:
- Remove the starter motor from the vehicle (usually secured with bolts).
- Inspect for any physical damage or signs of wear.
- Test the starter motor by applying direct battery voltage; if it does not engage, replace it.

4. Reassembly

Reattach the starter motor and ensure it is securely bolted.
Reconnect the battery terminals (positive first, then negative).
Ensure all connections are tight and check for any loose wiring.
