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

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a flat surface and the engine is off.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

• Tools Required: Socket set, funnel, drain pan.
• Remove the transmission drain plug and allow old fluid to drain into the pan.
• Replace the drain plug and torque it to manufacturer specifications.
• Use a funnel to fill the transmission with the correct type of fluid (consult the owner's manual for specifications).
• Check the fluid level using the dipstick and add more fluid if necessary.

3. Inspect and Repair Wiring/Connectors

• Visually inspect the wiring harness leading to the TCM for any signs of wear, fraying, or corrosion.
• Use a multimeter to ensure continuity in the wires.
• Repair or replace any damaged wiring or connectors.

4. Replace Transmission Control Module (if necessary)

• Tools Required: Socket set, torque wrench.
• Remove any components obstructing access to the TCM, such as the air intake or battery.
• Disconnect the electrical connectors from the TCM.
• Remove the mounting bolts and take out the old TCM.
• Install the new TCM by reversing the removal steps, ensuring all connectors are reattached securely.
• Torque the mounting bolts to manufacturer specifications.
