Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, load tester, socket set, and wrenches.
Ensure the vehicle is in a safe, flat location and turn off the ignition.

2. Battery Inspection and Replacement

Disconnect Battery
- Use a wrench to loosen the negative terminal first, then the positive terminal.
- Safety Warning: Disconnect the battery before working on electrical systems to prevent shorts.
Clean Battery Terminals
- Inspect battery terminals for corrosion. If present, clean with a mixture of baking soda and water.
- Use a wire brush to remove any buildup.
Test and Replace Battery (if necessary)
- If the battery voltage is low or fails the load test, replace it with a new one.
- Install the new battery by connecting the positive terminal first, followed by the negative terminal.

3. Starter Motor and Solenoid Check

Inspect Wiring to Starter Motor
- Remove any obstructions to access the starter motor.
- Inspect the wiring for any frays or damage and repair or replace as necessary.
Test Starter Motor
- Use a multimeter to check the voltage at the starter terminal while someone turns the ignition key.
- If there is no voltage, the ignition switch or wiring may be faulty.
Replace Starter Motor (if necessary)
- If the starter motor is defective, remove it by unscrewing the mounting bolts and unplugging the electrical connector.
- Install the new starter motor by reversing the removal steps and torque the bolts to manufacturer specifications.
