Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe area, parked on a flat surface.
Disconnect the negative battery terminal.

2. Battery Inspection

Sub-step 1: Clean battery terminals using a wire brush to remove any corrosion.
Sub-step 2: Tighten the battery connections to ensure a secure fit.
Sub-step 3: If the battery is weak, replace it with a new, fully charged battery (12V, Group size 51R or as per specification).

3. Starter Motor Inspection

Sub-step 1: Locate the starter motor (typically near the transmission).
Sub-step 2: Disconnect the wiring harness and the power cable from the starter motor.
Sub-step 3: Inspect for any physical damage or corrosion.
Sub-step 4: Test the starter motor by applying direct power from the battery (make sure the vehicle is in neutral).
Sub-step 5: If the starter does not engage, replace it with a new unit.

4. Ignition Switch Check

Sub-step 1: Inspect the ignition switch wiring for any damage or loose connections.
Sub-step 2: If necessary, replace the ignition switch following the manufacturer’s service manual for disassembly and reassembly.
