how to fix the P0700 code in my Toyota Camry Seventh Generation (2012-2017)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Transmission Fluid Check

• Tools Required: Transmission fluid dipstick or fluid level gauge.
• Remove the dipstick or fluid level gauge from the transmission.
• Check the fluid level; add the appropriate type of transmission fluid if low.
• Inspect fluid condition; if the fluid is dark or has a burnt smell, drain and replace it.

3. Inspect and Repair Wiring

• Tools Required: Multimeter, wire connectors.
• Visually inspect the wiring harness connected to the TCM for frays or corrosion.
• Use a multimeter to test for continuity and voltage at the TCM connector. Repair any damaged wires or connections found.

4. TCM Testing and Replacement

• Tools Required: OBD-II scanner, multimeter, socket set.
• If all wiring checks out, use the OBD-II scanner to clear the P0700 code and see if it returns after a test drive.
• If the code returns, consider replacing the TCM.
  • Remove the TCM from its mounting location.
  • Disconnect the wiring harness and remove any bolts securing the module.
  • Install the new TCM by securing it with bolts and reconnecting the wiring harness.

5. Final Checks and Reassembly

• Recheck the transmission fluid level after repairs and add fluid if necessary.
• Reconnect the negative battery terminal.
• Ensure all components are securely reassembled.
