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

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a flat surface and safely secured with wheel chocks.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

• Tools Required: Transmission dipstick, funnel, fresh transmission fluid
• Remove the transmission dipstick and check the fluid level and color.
• If low, add the appropriate type of transmission fluid as specified in the owner’s manual.
• If the fluid is dark or smells burnt, consider a transmission fluid change.

3. Inspect Wiring and Connectors

• Tools Required: Multimeter, basic hand tools
• Carefully inspect the wiring harness connected to the TCM for frays or breaks.
• Use a multimeter to check for continuity in the wires.
• Reconnect any loose or damaged connectors and repair as necessary.

4. Replace Transmission Control Module (if necessary)

• Tools Required: Socket set, torque wrench
• Locate the TCM (usually found near the transmission).
• Remove any screws or bolts securing the module.
• Disconnect the electrical connectors from the module.
• Replace with a new TCM, ensuring all connectors are securely reattached.
• Torque screws/bolts to the manufacturer’s specifications.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and allow it to reach operating temperature.
• Take the vehicle for a test drive to ensure proper shifting and performance.
