1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shorts.
Gather necessary tools and parts.

2. Battery Inspection and Replacement

Tools Required: Multimeter, battery terminal cleaner, socket set.
Inspect the battery terminals for corrosion. Clean with a terminal cleaner if necessary.
Measure the battery voltage with a multimeter. If it’s below 12.4 volts, replace the battery.
- Sub-step: Disconnect both battery terminals (negative first, then positive).
- Sub-step: Remove the battery hold-down bracket and lift the battery out.
- Sub-step: Install the new battery in reverse order and ensure terminals are tight.

3. Starter Motor Testing/Replacement

Tools Required: Socket set, wrenches, torque wrench.
If the battery is good, locate the starter motor.
- Sub-step: Disconnect electrical connectors from the starter.
- Sub-step: Remove the starter mounting bolts using a socket set.
- Sub-step: Pull the starter motor out of the engine bay.
