Solution

1. Preparation

Ensure the vehicle is in park (or neutral for manual transmission).
Gather all necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from the battery terminals using a wire brush.
- Tighten any loose connections.
Test and Replace Battery
- If the battery voltage is below 12.4 volts or fails the load test, replace the battery.
- Remove the negative terminal first, followed by the positive terminal.
- Remove the battery hold-down bracket and lift the battery out.
- Place the new battery in the tray, secure it with the hold-down bracket, and connect the positive terminal first followed by the negative terminal.

3. Starter Relay and Motor Inspection

Check Starter Relay
- Locate the starter relay in the fuse box (refer to the owner's manual for position).
- Swap it with another relay of the same type to test if it resolves the issue.
Inspect Starter Motor
- Locate the starter motor (usually near the transmission).
- Check the wiring and connections for any signs of wear or damage.
- Using a multimeter, test the voltage at the starter motor when attempting to start the vehicle.
Replace Starter Motor (if necessary)
- If the starter motor is faulty, disconnect the battery.
- Remove the wiring harness and mounting bolts from the starter.
- Install the new starter motor and reconnect the wiring.
