Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Ensure the vehicle is in park (automatic) or neutral (manual).

2. Battery Inspection

Tools Required: Multimeter, wire brush, wrench set
Inspect battery terminals for corrosion; clean with a wire brush if necessary.
Tighten any loose connections to ensure a good electrical contact.

3. Battery Replacement (if necessary)

Tools Required: Socket set, torque wrench
Remove the negative terminal first, followed by the positive terminal.
Unbolt the battery hold-down clamp and carefully lift the battery out.
Install the new battery, securing it with the hold-down clamp.
Connect the positive terminal first, followed by the negative terminal.
Torque the battery terminals to manufacturer specifications (usually 10-12 Nm).

4. Starter Motor Testing

Tools Required: Jumper wire, multimeter
Locate the starter motor (usually near the bottom of the engine near the transmission).
Disconnect the starter solenoid wire.
Use a jumper wire to connect the positive battery terminal directly to the starter motor terminal.
If the starter engages and the engine cranks, replace the starter motor.

5. Final Checks

Reconnect the battery and ensure all connections are secure.
Recheck all fuses related to the starting system and replace if blown.
Test the ignition switch by turning the key and checking for normal function.
