1. Preparation

Gather tools: multimeter, socket set, screwdriver, remote starter switch.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Battery Inspection

Sub-step 1: Reconnect the battery terminal and check voltage again. If the voltage is low, charge or replace the battery.
Sub-step 2: Clean battery terminals with a wire brush if corrosion is present, reattach securely.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor; it is typically mounted on the engine block near the transmission.
Sub-step 2: Disconnect the wiring harness from the starter.
Sub-step 3: Use the remote starter switch to connect the positive terminal of the starter to the battery positive terminal.
Sub-step 4: If the starter motor engages and turns the engine over, replace the ignition switch or battery cables as needed.

4. Fuses and Wiring Check

Sub-step 1: Inspect the fuse box for blown fuses related to the starting system and replace any that are faulty.
