Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required:
- Multimeter
- Socket set
- Jumper cables
- OBD-II scanner
- Remote starter switch (optional)
Safety Warnings:
- Disconnect the negative battery terminal before working on electrical systems.

2. Battery Inspection and Replacement

Inspect the Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from the terminals and cable ends using a wire brush.
Test the Battery:
- Use the multimeter to check the voltage. If below 12.4 volts, charge or replace the battery.
Replace the Battery (if necessary):
- Disconnect the old battery and remove it from the vehicle.
- Place the new battery in the battery tray, ensuring correct orientation.
- Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection and Replacement

Test the Starter Motor:
- If the battery is good, locate the starter motor (typically near the transmission bell housing).
- Use a remote starter switch to directly engage the starter motor.
- If the starter engages and cranks the engine, the starter may need replacing.
Replace the Starter Motor (if necessary):
- Disconnect the battery again.
- Remove any engine covers obstructing access to the starter motor.
- Disconnect the electrical connectors from the starter and remove the mounting bolts.
- Install the new starter motor in reverse order, tightening bolts to manufacturer specifications (usually around 15-20 Nm).
- Reconnect the battery and test the start function.
