1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and battery terminal cleaner.
Ensure the vehicle is in park or neutral and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Battery Inspection and Replacement

Sub-step 1: Inspect the battery for signs of damage or leakage.
Sub-step 2: If the battery voltage is low or the battery is over 3 years old, replace it with a new one.
Tool Required: Socket set for battery removal.
Safety Warning: Always wear safety glasses and gloves when handling batteries.

3. Starter Motor Inspection

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Locate the starter motor; typically found near the engine block.
Sub-step 3: Inspect the starter motor connections for corrosion or looseness.
Sub-step 4: If the connections are secure and clean, test the starter using a multimeter for continuity.
Sub-step 5: If the starter is faulty, remove it by unscrewing the mounting bolts and disconnecting the electrical connector. Install the new starter and secure it with the mounting bolts. Torque bolts to manufacturer specifications (usually around 20-30 ft-lbs).
