Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and screwdriver.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative terminal of the battery for safety.

2. Battery Inspection and Replacement

Check Battery Voltage
- Use a multimeter to measure the voltage across the battery terminals.
- A healthy battery should read around 12.6 volts. If it's below 12.4 volts, charge or replace the battery.
Inspect Battery Connections
- Remove the battery terminals (negative first, then positive).
- Clean terminals and battery posts using a wire brush.
- Reconnect terminals securely (positive first, then negative).

3. Starter Motor Check

Access Starter Motor
- Raise the vehicle and secure it with jack stands.
- Locate the starter motor (usually near the transmission).
Test Starter Voltage
- Connect the multimeter to the starter terminal while a helper turns the ignition to the start position.
- Ensure the voltage is at least 9 volts during cranking; replace the starter if it's below this value.

4. Replace the Battery or Starter

Battery Replacement
- Remove the old battery from the tray.
- Install the new battery in reverse order of removal.
- Torque the battery terminals to manufacturer specifications.
Starter Replacement (if necessary)
- Disconnect the wiring harness and bolts from the old starter.
- Install the new starter in reverse order, ensuring all connections are secure.
