Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety during the process.

2. Battery Inspection and Replacement

Tools Required: Multimeter, wrench set, battery terminal cleaner, new battery (if needed).
Check battery voltage, if below 12.4 volts, charge or replace.
Clean battery terminals using a battery terminal cleaner and ensure a tight connection.
If replacing the battery:
1. Remove the old battery by loosening the hold-down bracket and disconnecting the positive terminal first, followed by the negative terminal.
2. Install the new battery in the reverse order, ensuring terminals are connected tightly.

3. Starter Motor Inspection

Tools Required: Socket set, torque wrench.
If the battery is good, inspect the starter motor:
1. Locate the starter motor under the vehicle.
2. Remove wiring harness connected to the starter motor.
3. Unbolt the starter motor from its mounting using a socket set.
4. Test the starter motor by connecting it directly to the battery; replace if it does not engage.

4. Key Fob and Ignition System Check

Tools Required: Key fob battery replacement kit (if needed).
If the key fob is not recognized:
1. Open the key fob and replace the battery if necessary.
2. Re-sync the key fob with the vehicle following the manufacturer’s instructions.
Inspect ignition switch for wear; replace if malfunctioning.
