how to troubleshoot P0700 code on Tesla Outback 6th Generation (2020-2024)

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is on a level surface and securely lifted with jack stands if necessary.

2. Inspect and Change Transmission Fluid

• Tools Required: Socket set, transmission fluid pump, fluid catch pan.
• Sub-steps:
  1. Remove the transmission fluid pan using the socket set.
  2. Allow the old fluid to drain completely into the catch pan.
  3. Inspect the fluid for metal shavings or burnt smell.
  4. Replace the transmission fluid filter if necessary.
  5. Reinstall the pan and torque bolts to manufacturer specifications (typically around 10-12 ft-lbs).

3. Check and Repair Wiring and Connectors

• Tools Required: Multimeter, electrical cleaner.
• Sub-steps:
  1. Disconnect the battery before working on electrical components.
  2. Visually inspect the wiring harness for any frays, cuts, or corrosion.
  3. Use the multimeter to test for continuity in the wiring.
  4. Clean any corroded connectors with electrical cleaner and reconnect securely.

4. Test Transmission Control Module

• Tools Required: OBD-II scanner, multimeter.
• Sub-steps:
  1. Reconnect the battery.
  2. Use the OBD-II scanner to check for any new or persistent codes.
  3. If the P0700 code is still present, perform a voltage test on the transmission control module with the multimeter.
  4. If the module is faulty, replace it with a new unit according to manufacturer specifications.
