Solution

1. Preparation

Tools Required:
- Multimeter
- Socket set
- Screwdriver set
- OBD-II scanner
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Inspect Battery Terminals
- Remove any corrosion from the terminals using a wire brush.
- Ensure the terminals are tightly secured to the battery posts.
Test Battery Voltage
- Reconnect the negative terminal and use a multimeter to check the battery voltage. If it’s below 12.4 volts, jump-start the vehicle or replace the battery if it fails to hold charge.

3. Starter Relay Test

Locate the Starter Relay
- Find the relay in the fuse box (refer to the owner's manual for location).
Swap Relay
- Replace it with another relay of the same type to test functionality.

4. Starter Circuit Inspection

Voltage Drop Test
- Reconnect the battery and measure voltage at the starter terminal while a helper turns the key to the start position. A reading over 0.5 volts indicates poor connections.
Inspect Wiring
- Check all wiring from the battery to the starter for damage or loose connections.

5. Starter Replacement (if necessary)

Remove Starter
- Disconnect the battery terminals again. Remove any components obstructing access to the starter.
- Unbolt the starter from the engine block and carefully disconnect the electrical connectors.
Install New Starter
- Position the new starter in place and secure it with bolts. Reconnect the electrical connectors and ensure all connections are tight.

6. Final Checks

Reconnect Battery
- Reconnect the negative battery terminal.
Test Start
- Attempt to start the engine to verify repairs.
