Solution

1. Preparation

Gather tools: multimeter, socket set, battery terminal cleaner, jumper cables.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection and Replacement

Step 1: Disconnect the negative terminal of the battery.
Step 2: Clean any corrosion from the battery terminals using a battery terminal cleaner.
Step 3: Reconnect the negative terminal securely.
Step 4: If the battery is faulty (below 12.4 volts), remove it using a socket set and replace with a new battery.
- Tools Required: Socket set, battery terminal cleaner.
- Safety Warning: Always disconnect the negative terminal first to avoid short circuits.

3. Starter Motor Testing and Replacement

Step 1: If the battery is good, locate the starter motor (generally located near the transmission).
Step 2: Disconnect the electrical connector and the battery cable from the starter motor.
Step 3: Test the starter motor by applying 12 volts directly from the battery to the starter terminal.
Step 4: If the starter does not engage, replace the starter motor.
- Tools Required: Socket set, multimeter.
- Torque Specification: Ensure all bolts are tightened to manufacturer specifications.
