Solution

1. Preparation

Gather tools: multimeter, jumper cables, socket set, and torque wrench.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Reconnect the battery terminals if they were disconnected.
Clean the battery terminals and cable connections using a wire brush.
Tighten the battery terminal connections to the manufacturer's specifications.

3. Jump-Start the Vehicle

Connect jumper cables: red to the positive terminal of the dead battery and red to the positive terminal of the donor battery.
Connect black to the negative terminal of the donor battery, and the other end to a grounded metal surface on the dead vehicle.
Start the donor vehicle and then attempt to start the Honda Pilot.

4. Starter Relay and Fuse Check

Locate the fuse box and identify the starter relay and fuses.
Remove and inspect the starter relay; replace it if there is any sign of damage.
Replace any blown fuses related to the starting system with fuses of the same amperage.

5. Starter Motor Inspection

If the vehicle still does not start, inspect the starter motor.
Remove starter motor bolts and disconnect wiring.
Test the starter motor by connecting it directly to the battery; if it does not engage, replace it.
