Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery cable to prevent electrical shock.

2. Battery Replacement (if faulty)

Remove the positive battery terminal using a socket set.
Remove the negative battery terminal.
Unfasten any mounting brackets and lift the battery out of the tray.
Place the new battery in the tray, ensuring it is securely positioned.
Reconnect the negative terminal first, followed by the positive terminal.
Tighten all connections securely.

3. Starter Motor Inspection/Replacement (if necessary)

Disconnect the negative battery cable again.
Locate the starter motor, typically near where the engine and transmission meet.
Remove any covers or shields obstructing access to the starter.
Disconnect the wiring harness and the positive cable from the starter.
Unbolt the starter motor from its mount (note torque specifications for reinstallation).
Remove the old starter and install the new starter motor.
Reconnect the wiring harness and positive cable to the new starter.
Reinstall any covers or shields removed earlier.
Reconnect the negative battery cable.
