Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery negative terminal to ensure safety.
Tools Required: Multimeter, socket set, screwdrivers, OBD-II scanner.

2. Battery Inspection

Sub-step 1: Reconnect battery terminals if they were loose or corroded.
Sub-step 2: Charge the battery if the voltage is low (below 12.6 volts).
Sub-step 3: Replace the battery if it fails to hold a charge after testing.

3. Starter Relay and Fuse Inspection

Sub-step 1: Locate the starter relay in the fuse box (consult the owner’s manual for exact location).
Sub-step 2: Swap the starter relay with a similar relay to test functionality.
Sub-step 3: Replace any blown fuses related to the starting system.

4. Ignition Switch Testing

Sub-step 1: Remove the ignition switch from the steering column (refer to the repair manual for disassembly instructions).
Sub-step 2: Use a multimeter to check for continuity in the ignition switch; replace if defective.

5. Starter Motor Inspection

Sub-step 1: Locate the starter motor (under the engine near the transmission).
Sub-step 2: Inspect the wiring harness and connections for damage or looseness.
Sub-step 3: Test the starter motor directly by applying battery voltage to the terminals; replace if it does not engage.
