how to fix the P0700 code on my Toyota RAV4 XA40 (2013-2018)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and set the parking brake.
• Disconnect the negative battery terminal to avoid any electrical shorts.

2. Inspect and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, fluid catch pan, funnel, socket set.
• Remove the transmission fluid pan using a socket wrench.
• Allow the old fluid to drain completely into the catch pan.
• Inspect the fluid; if it is dark or has a burnt smell, it needs replacement.
• Replace the transmission filter if applicable.
• Reinstall the fluid pan with a new gasket and torque the bolts to manufacturer specifications.
• Refill the transmission with new fluid, ensuring the correct type is used (refer to the owner’s manual).

3. Repair Wiring Issues

• Tools Required: Multimeter, wire stripper/crimper, electrical tape.
• Inspect the wiring harness connected to the TCM and transmission for damage.
• Use a multimeter to check for continuity and proper voltage.
• Repair any damaged wires or connections as necessary using wire strippers and crimpers.
• Secure all connections and cover them with electrical tape to prevent exposure.

4. Replace Transmission Control Module (if necessary)

• Tools Required: Socket set, torque wrench.
• Locate the TCM (usually found near the transmission or under the dashboard).
• Disconnect the wiring harness from the TCM.
• Remove the TCM by unscrewing it from its mounting location.
• Install the new TCM, ensuring it is secured properly.
• Reconnect the wiring harness and any other components removed.
