Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and torque wrench.
Ensure the vehicle is in park or neutral with the parking brake engaged.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Remove any corrosion using a wire brush and clean the terminals.
- Ensure the connections are tight; re-tighten if necessary.
Load Test Battery:
- Connect a load tester to the battery and apply a load for 10-15 seconds.
- If the voltage drops below 9.6 volts, replace the battery.
Replace Battery (if needed):
- Remove the battery hold-down clamp using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Install the new battery by connecting the positive terminal first, followed by the negative terminal.
- Secure the battery with the hold-down clamp.

3. Starter Inspection and Replacement

Check Starter Connections:
- Inspect the starter solenoid and wiring for cleanliness and tightness.
- Clean or replace corroded connections as needed.
Test Starter:
- Use a multimeter to check for voltage at the starter terminal when the ignition is turned.
- If no voltage is present, replace the ignition switch or check wiring continuity.
Replace Starter (if necessary):
- Disconnect the negative battery terminal again to ensure safety.
- Remove the starter mounting bolts using a socket set.
- Disconnect the wiring harnesses from the starter.
- Install the new starter in reverse order, ensuring all connections are tight.
- Reconnect the negative battery terminal.
