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

Solution

1. Preparation

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

2. Inspect and Replace Transmission Fluid (if needed)

• Tools Required: Transmission fluid pump, socket set, funnel.
• Check the transmission fluid level using the dipstick. If low, add the appropriate type of transmission fluid (refer to owner's manual for specifications).
• If the fluid is dark or has a burnt odor, replace it.
  • Sub-steps:
    1. Remove the transmission drain plug (if equipped) and drain the old fluid into a container.
    2. Replace the drain plug and torque to manufacturer's specifications.
    3. Use a fluid pump to fill the transmission with new fluid through the dipstick tube to the required level.

3. Inspect and Repair Wiring/Connector

• Tools Required: Multimeter, wire stripper/crimper.
• Inspect the wiring harness and connectors for the TCM.
  • Sub-steps:
    1. Disconnect the TCM connector.
    2. Check for bent pins or corrosion.
    3. Use a multimeter to test for continuity in the wiring.
    4. Repair any damaged wires or replace the connector if necessary.

4. Check and Replace Transmission Control Module (if necessary)

• Tools Required: Torque wrench, socket set.
• If previous steps do not resolve the issue, consider replacing the TCM.
  • Sub-steps:
    1. Remove the TCM mounting bolts and disconnect the wiring harness.
    2. Install the new TCM and secure it with bolts to the manufacturer's torque specifications.
    3. Reconnect the wiring harness.
