Solution

1. Preparation

Tools Required: Multimeter, socket set, OBD-II scanner, jumper cables
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery cover if applicable.
2. Clean the battery terminals with a wire brush to remove any corrosion.
3. Reconnect the terminals securely.
4. If the battery voltage is low, replace the battery with a new one (ensure it meets specifications: 12V, 70-90Ah).

3. Starter Motor Replacement (if necessary)

Sub-steps:
1. Locate the starter motor (usually found near the engine block).
2. Disconnect the wiring harness from the starter.
3. Remove the mounting bolts using the socket set (typically 2-3 bolts).
4. Carefully take out the starter motor from its position.
5. Install the new starter motor by reversing the removal steps.
6. Torque the mounting bolts to the manufacturer’s specification (typically around 30-40 Nm).

4. Final Checks

Reconnect the negative battery terminal.
Start the vehicle to ensure the repair was successful.
