Ensure the vehicle is in a safe working environment.
Disconnect the negative battery cable to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from terminals with a wire brush.
- Reconnect and test the battery voltage again; if below 12.4 volts, proceed to replacement.
Replace Battery
- Remove the old battery from the battery tray.
- Install a new battery, ensuring it matches the specifications for the Tacoma N300.
- Secure the battery and reconnect terminals (positive first, then negative).

3. Starter Motor Inspection and Replacement

Locate Starter Motor
- Access the starter motor, typically located near the transmission.
- Remove any components obstructing access, if necessary.
Test Starter
- Connect a multimeter to the starter terminals and check for voltage when the key is turned to the start position.
- If no voltage is present, the starter may be faulty.
Replace Starter
- Remove the starter motor by unscrewing the mounting bolts.
- Disconnect the wiring harness and remove the starter.
- Install the new starter by reversing the removal steps, ensuring all connections are secure.
