Solution

1. Preparation

Gather tools: multimeter, socket set, screwdrivers, OBD-II scanner, battery terminal cleaner.
Ensure the vehicle is in a safe and accessible area.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check Battery Condition

Sub-step 1: Reconnect the battery and measure the voltage with a multimeter. If it reads below 12.4V, proceed to jump-start or replace the battery.
Sub-step 2: If jump-starting, connect the jumper cables properly: positive to positive, negative to grounded metal on the vehicle.
Sub-step 3: Attempt to start the vehicle again after jump-starting.

3. Inspect Battery Connections

Sub-step 1: Remove the battery terminals using a socket set.
Sub-step 2: Clean any corrosion on the terminals and battery posts using a battery terminal cleaner.
Sub-step 3: Reattach terminals securely, starting with the positive terminal first.

4. Test Key Fob and Ignition System

Sub-step 1: Replace the battery in the key fob to ensure it is functioning correctly.
Sub-step 2: Attempt to start the vehicle with the key fob near the ignition sensor to ensure proper recognition.

5. Check Fuses and Relays

Sub-step 1: Locate the fuse box and check the ignition and starter fuses for continuity using a fuse tester.
Sub-step 2: Replace any blown fuses with the appropriate amperage rating.
Sub-step 3: Inspect the starter relay for proper functionality and replace if necessary.

6. Inspect Starter Motor Connections

Sub-step 1: Locate the starter motor and inspect the wiring harness for any signs of damage or disconnection.
Sub-step 2: Ensure the connections are tight and free of corrosion.
Sub-step 3: If necessary, test the starter motor by applying direct voltage from the battery to see if it engages.
