Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, battery terminal cleaner.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Battery Inspection and Replacement

Sub-steps:
1. Use a multimeter to check the battery voltage.
  - If voltage is below 12.4 volts, proceed to charge or replace the battery.
2. Clean the battery terminals with a terminal cleaner if corrosion is present.
3. Tighten loose connections on the battery terminals.
4. If the battery is faulty, replace it with a new one, ensuring the new battery is rated for the Honda Accord.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor, usually found near where the transmission meets the engine.
2. Disconnect the electrical connectors from the starter motor.
3. Check for continuity using a multimeter.
  - If there is no continuity, replace the starter motor.
4. Reconnect the starter motor and ensure all connections are tight.

4. Check Ignition Switch

Sub-steps:
1. Access the ignition switch by removing the steering column cover.
2. Use a multimeter to test the ignition switch for continuity when in the "start" position.
  - If it fails the test, replace the ignition switch.
3. Reassemble the steering column cover after repairs.
