Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, battery terminal cleaner, wrench set.
Disconnect the negative battery cable to prevent electrical shock.

2. Battery Inspection

Clean the battery terminals with a terminal cleaner to remove any corrosion.
Reconnection: Reconnect the battery terminals securely and ensure a good connection.

3. Starter Motor Testing

Locate the starter motor (usually near the bottom of the engine near the transmission).
Check the starter connections for tightness and corrosion.
If necessary, remove the starter motor:
1. Disconnect wiring harness from the starter.
2. Remove the bolts securing the starter (typically 2-3 bolts).
3. Carefully take the starter out.
Test the starter using a bench test with a jumper wire to see if it engages.

4. Battery Replacement (if needed)

If the battery voltage is low or the battery fails the test:
1. Replace it with a new battery of the correct size and capacity (usually Group 35 for Camry).
2. Reconnect the new battery terminals, ensuring they are tight.

5. Reinstall Starter (if removed)

Reinstall the starter motor by reversing the removal steps.
Tighten bolts to manufacturer specifications (typically around 15-20 ft-lbs).

6. Final Assembly

Reconnect the negative battery cable.
Start the vehicle to ensure proper function.
