Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, jumper cables, safety gloves, and eye protection.
Disconnect the negative battery terminal to ensure safety during inspection and repairs.

2. Battery Inspection and Replacement

Sub-steps:
1. Clean any corrosion from the battery terminals using a wire brush and a solution of baking soda and water.
2. Reconnect the terminals securely after cleaning.
3. If the battery voltage is below 12.4 volts, charge the battery or replace it if it fails to hold a charge.
4. Confirm the battery rating matches the specifications for the Toyota Corolla E210.

3. Starter Motor Testing and Replacement

Sub-steps:
1. If the battery is confirmed good, locate the starter motor (usually near the engine's transmission).
2. Disconnect the starter motor's electrical connections.
3. Test the starter motor by connecting power directly to it to see if it engages.
4. If the starter does not engage, replace the starter motor with a new one, ensuring to torque the mounting bolts to the manufacturer’s specifications (usually around 20-30 ft-lbs).

4. System Reassembly

Reconnect the battery terminals, starting with the positive connection followed by the negative.
Ensure all tools and equipment are removed from the engine bay before closing the hood.
