what does it mean when my Toyota RAV4 XA40 (2013-2018) is showing a P0700 code

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and secure with jack stands.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Transmission Fluid

• Remove the transmission dipstick and check fluid level.
• If low, fill with the manufacturer-recommended ATF (Automatic Transmission Fluid) until it reaches the proper level.
• Inspect fluid for discoloration or burnt smell, indicating potential issues.

3. Check Wiring and Connectors

• Visually inspect the wiring harness connected to the TCM.
• Look for frayed wires, loose connections, or corrosion.
• If damaged, repair or replace the affected wiring and connectors.

4. Test Transmission Control Solenoids

• Locate the solenoids on the transmission.
• Disconnect the electrical connectors and test with a multimeter for proper resistance.
• Replace any solenoids found to be faulty according to the specifications.

5. Clear Codes and Test Drive

• Reconnect the battery terminal and use the OBD-II scanner to clear the P0700 code.
• Perform a test drive to ensure proper shifting and operation of the transmission.
