Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, jumper cables, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Step 1: Open the hood and locate the battery.
Step 2: Check battery terminals for corrosion; clean with a wire brush if necessary.
Step 3: Tighten loose connections securely.

3. Battery Voltage Test

Step 1: Set the multimeter to DC voltage.
Step 2: Connect the multimeter leads to the battery terminals (red to positive, black to negative).
Step 3: Read the voltage; if below 12.4 volts, proceed to charge or replace the battery.

4. Jump-Start Procedure

Step 1: Connect jumper cables: red to the positive terminal of the dead battery and the other red to the positive terminal of the good battery.
Step 2: Connect black to the negative terminal of the good battery and the other black to an unpainted metal surface on the dead vehicle.
Step 3: Start the donor vehicle and then attempt to start the Honda CR-V.

5. Starter Motor Testing

Step 1: Disconnect the starter motor electrical connector.
Step 2: Use jumper cables to connect the starter directly to the battery.
Step 3: If the starter engages, it may need replacement; if not, further investigation into the ignition switch or wiring may be necessary.
