Diagnostic Steps

1
Check the battery voltage using a multimeter; it should read around 12.6 volts for a fully charged battery.
2
Inspect battery terminals for corrosion or loose connections.
3
Test the starter motor by bypassing the ignition system with a direct connection from the battery to the starter's terminal.
4
Examine the fuses related to the starting system for any blown fuses.
5
Inspect the ignition switch operation and check for any faults.

Solution

1. Preparation

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

2. Battery Inspection

Sub-steps:
1. Disconnect the negative (-) battery terminal using a wrench.
2. Clean the battery terminals with a wire brush to remove corrosion.
3. Reconnect the negative terminal and ensure it is tight.

3. Starter Motor Test

Sub-steps:
1. Locate the starter motor (typically near the transmission).
2. Disconnect the starter motor's electrical connector.
3. Use a multimeter to check for voltage at the starter terminal while a helper turns the ignition key to the start position.
4. If voltage is present but the starter doesn't engage, replace the starter motor.

4. Replace Battery (if needed)

Sub-steps:
1. Disconnect the positive (+) terminal first, followed by the negative (-) terminal.
2. Remove the battery hold-down clamp and lift the battery out.
3. Install the new battery, ensuring correct polarity (positive first, then negative).
4. Secure the battery with the hold-down clamp.

5. Final Checks

Sub-steps:
1. Recheck all connections and ensure they are secure.
2. Attempt to start the vehicle again.
