how to fix P0700 code on my Toyota RAV4 Fourth Generation (2013-2018)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Allow the vehicle to cool down if it has been running.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, funnel, 10mm socket, and ratchet.
• Sub-steps:
  1. Locate the transmission fluid dipstick or fill plug (depending on the transmission type).
  2. Remove the dipstick or fill plug and check the fluid level; add fluid as needed.
  3. If the fluid is dirty or burnt, drain the transmission fluid using a fluid pump and replace it with new, manufacturer-recommended fluid (e.g., Toyota ATF WS).
  4. Reinstall the dipstick or fill plug securely.

3. Inspect and Repair Wiring and Connectors

• Tools Required: Wire strippers, electrical tape, multimeter.
• Sub-steps:
  1. Visually inspect all wiring and connectors leading to the TCM for signs of wear or damage.
  2. Use a multimeter to check for continuity and proper voltage at the connectors.
  3. Repair or replace any damaged wiring or connectors as necessary.
  4. Secure any loose connections with electrical tape or heat shrink tubing.

4. Replace Faulty TCM or Solenoids

• Tools Required: 10mm socket, ratchet, torque wrench, new TCM or solenoids.
• Sub-steps:
  1. Locate the TCM, usually found near the transmission or under the dashboard.
  2. Disconnect the electrical connectors and remove the mounting bolts using a 10mm socket.
  3. Carefully remove the TCM from its housing.
  4. If replacing solenoids, locate them on the transmission and remove them using the appropriate tools.
  5. Install the new TCM or solenoids in reverse order, ensuring all electrical connections are secure.
  6. Torque the mounting bolts to the manufacturer's specifications.
