Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Reconnect the battery and check the voltage again with the multimeter.
- If the voltage is below 12.4 volts, jump-start the vehicle or replace the battery.

3. Starter Relay Replacement

Locate the starter relay in the fuse box.
Remove the relay by pulling it straight out.
Insert the new relay firmly into the socket.

4. Starter Motor Check

Locate the starter motor, typically found near the engine block.
Disconnect the wiring harness and the battery cable from the starter.
Remove the starter motor bolts (usually 2-3) using a socket set.
Inspect the starter for any signs of wear or damage. If faulty, replace with a new starter.

5. Reassembly

Reinstall the starter motor and secure it with the bolts, tightening to manufacturer specifications (typically 15-25 ft-lbs).
Reconnect the wiring harness and battery cable to the starter.
Reconnect the negative battery terminal.
