Solution

1. Preparation

Gather tools: multimeter, jumper cables, socket set, remote starter switch.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Replacement

Disconnect the negative (-) battery terminal using a socket set.
Disconnect the positive (+) battery terminal.
Clean any corrosion from the terminals and battery posts using a wire brush.
If battery voltage is low (below 12.4 volts), replace the battery.
- Parts Required: New battery (ensure correct size and specifications).
Reconnect the positive (+) terminal first, then the negative (-) terminal.

3. Starter Motor Testing and Replacement

Locate the starter motor, typically found on the lower side of the engine near the transmission.
Remove the electrical connections from the starter motor.
Use a remote starter switch to bypass the ignition and test if the starter motor engages.
- If it clicks but does not turn, the starter may be faulty.
If replacing the starter:
- Remove the starter motor mounting bolts.
- Install the new starter in reverse order, ensuring to torque bolts to manufacturer specifications (typically around 10-15 ft-lbs).
- Reconnect electrical connections securely.
