Solution

1. Preparation

Gather tools: multimeter, jumper wires, OBD-II scanner, socket set, and flashlight.
Ensure the vehicle is in a safe working environment and on a flat surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Battery

Sub-step 1: Reconnect the battery and check the voltage with a multimeter.
Sub-step 2: If voltage is low, charge the battery or replace if necessary.
Sub-step 3: Clean the battery terminals with a wire brush and reconnect securely.

3. Test Starter Motor

Sub-step 1: Locate the starter motor (usually near the transmission).
Sub-step 2: Use jumper wires to connect the starter solenoid terminal directly to the battery positive terminal.
Sub-step 3: If the starter engages and the engine cranks, replace the starter motor; if not, proceed to the next step.

4. Check Neutral Safety Switch

Sub-step 1: Disconnect the wiring harness from the neutral safety switch located on the transmission.
Sub-step 2: Use a multimeter to check for continuity when the transmission is in both park and neutral positions.
Sub-step 3: Replace the neutral safety switch if no continuity is found.

5. Scan for Error Codes

Sub-step 1: Connect the OBD-II scanner to the vehicle's diagnostic port.
Sub-step 2: Retrieve any stored error codes that may indicate issues related to the ignition system or immobilizer.
Sub-step 3: Address specific codes according to manufacturer guidelines.
