Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Multimeter, socket set, wrench set, OBD-II scanner, jumper cables.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Battery Check and Replacement

Battery Testing
- Connect the multimeter to the battery terminals; check voltage.
- If voltage is below 12.4 volts, consider charging or replacing the battery.
Battery Replacement
- If replacing, disconnect the negative terminal first, followed by the positive terminal.
- Remove the battery hold-down bracket and lift the battery out.
- Install the new battery by placing it in position, securing it with the bracket.
- Connect the positive terminal first, then the negative terminal.

3. Starter Relay Inspection

Remove Starter Relay
- Locate the starter relay in the fuse box (check the owner's manual for exact location).
- Use a socket to remove the relay.
Check Relay Function
- Swap it with another relay of the same type from the fuse box.
- Attempt to start the vehicle; if it starts, replace the faulty relay.

4. Starter Motor Test

Access Starter Motor
- Raise the vehicle using jack stands for safety.
- Locate the starter motor; it is usually mounted near the transmission.
Inspect Wiring
- Check the wiring connected to the starter for corrosion or damage.
- Repair or replace any damaged wires.
Test Starter Function
- Use jumper cables to bypass the ignition switch and directly power the starter.
- If the starter engages and the engine cranks, replace the starter motor.
