Solution

1. Preparation

Gather tools and parts necessary for repair.
Disconnect the negative battery cable to ensure safety.
Ensure the vehicle is in a safe workspace.

2. Battery Inspection and Replacement

Inspect Battery Condition
- Clean battery terminals with a wire brush to remove corrosion.
- Tighten any loose connections on the battery terminals.
Test Battery Voltage
- Use a multimeter to measure the voltage; replace the battery if below 12.4 volts.
- If replacing, ensure the new battery matches the specifications (typically Group Size 24F for RAV4).
Reconnect Battery
- Reconnect the negative terminal and ensure it is tight.

3. Starter Motor Testing and Replacement

Test Starter Motor
- Locate the starter motor and use jumper cables to connect directly to the battery.
- If it turns over, the starter is functioning; if not, proceed to replace it.
Remove Starter
- Disconnect the electrical connections from the starter (ensure negative battery is disconnected).
- Remove bolts securing the starter (typically two).
- Carefully maneuver the starter out of its location.
Install New Starter
- Position the new starter in place and secure it with bolts to the specified torque (usually around 36-48 ft-lbs).
- Reconnect electrical connections ensuring they are secure.

4. Ignition Switch Inspection

Remove Steering Column Covers
- Use a screwdriver to remove screws securing the steering column covers.
Inspect Ignition Switch
- Check for wear or damage; if faulty, replace the ignition switch by disconnecting its connector and unscrewing it from the steering column.
Reassemble
- Reattach the steering column covers and ensure all screws are tightened.
