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

Solution

1. Preparation

• Gather Tools and Parts: Ensure you have an OBD-II scanner, multimeter, socket set, torque wrench, transmission fluid, and any necessary replacement parts.
• Safety: Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

• Fluid Level: Locate the transmission dipstick. Remove it, wipe it clean, and reinsert it to check the fluid level.
• Condition: If the fluid is dark or smells burnt, a fluid change may be necessary.
  • Fluid Change: Drain the old fluid and replace it with the manufacturer-recommended transmission fluid.

3. Inspect Wiring and Connectors

• Visual Inspection: Check the wiring harness and connectors for any signs of wear, fraying, or corrosion.
• Repair/Replace: If damage is found, repair the wiring or replace the connectors as needed.

4. Test and Replace TCM

• TCM Testing: Use a multimeter to check the TCM for proper voltage output. Compare readings to manufacturer specifications.
• Replacement: If the TCM is faulty, remove it (usually involves removing screws and disconnecting wiring) and install a new unit, ensuring all connections are secure.

5. Inspect and Replace Transmission Solenoids

• Access Solenoids: Remove the transmission pan to access the solenoids.
• Testing: Use a multimeter to test for continuity and resistance in the solenoids.
• Replacement: If any solenoid is found to be defective, replace it with a new one and reassemble the transmission pan with a new gasket.
