Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery cable to prevent electrical shock.
Gather tools: multimeter, socket set, and wire brush.

2. Battery Inspection and Replacement

Check Battery Condition:
- Clean the battery terminals with a wire brush to remove any corrosion.
- Reconnect the battery and test the voltage again.
Replace Battery (if necessary):
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and install the new battery in reverse order (negative first, then positive).
- Torque the terminal connections to manufacturer specifications.

3. Starter and Solenoid Assessment

Inspect the Starter:
- Locate the starter underneath the vehicle.
- Disconnect the wiring harness and the battery cable from the starter.
- Remove the starter mounting bolts using a socket set.
- Inspect the starter for physical damage or wear.
Test the Starter:
- Use a multimeter to test the starter’s functionality by applying direct power to the starter terminal. If it does not engage, replace the starter.

4. Check and Replace Fuses

Inspect Fuses:
- Locate the fuse box and check the fuses related to the starting system.
- Replace any blown fuses with the appropriate amperage.

5. Reassemble and Test

Reconnect all components, ensuring all connections are secure.
Reconnect the negative battery cable.
Attempt to start the vehicle to check if the issue is resolved.
