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

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery's negative terminal to prevent electrical shock.

2. Check Transmission Fluid

• Remove the transmission dipstick (if equipped) and check fluid level.
• If low, add the manufacturer-recommended transmission fluid until it reaches the proper level.
• If the fluid is dark or smells burnt, consider a transmission fluid change.

3. Inspect Wiring and Connectors

• Visually inspect the wiring harness connected to the TCM for any fraying or damage.
• Clean any corrosion from connectors using electrical contact cleaner.
• Reconnect any loose connections securely.

4. Replace Transmission Control Module (if necessary)

• If testing confirms a faulty TCM, remove the TCM:
  1. Locate the TCM (usually under the dashboard or near the transmission).
  2. Unscrew any mounting bolts using a socket set.
  3. Disconnect the wiring harness from the TCM.
• Install the new TCM:
  1. Connect the wiring harness to the new TCM.
  2. Secure it with the mounting bolts, tightening to manufacturer specifications.

5. Reconnect Battery and Clear Codes

• Reconnect the negative terminal of the battery.
• Use the OBD-II scanner to clear the P0700 code and any associated codes.
• Start the vehicle and allow it to warm up.
