how to fix P0700 code on my Tesla Outback 5th Generation (2015-2019)

Solution

1. Preparation

• Gather tools (OBD-II scanner, multimeter, socket set, torque wrench, fluid catch pan).
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent any electrical shorts.

2. Transmission Fluid Inspection

• Remove the transmission dipstick or access point.
• Check the fluid level; add fluid if low (use manufacturer-approved transmission fluid).
• If the fluid is dark or has a burnt smell, perform a fluid change.
  • Sub-steps:
    • Drain the old fluid into a catch pan.
    • Replace the transmission filter (if applicable).
    • Refill with new transmission fluid as per manufacturer specifications (usually around 5-10 quarts).

3. Wiring and Connector Repair

• Inspect the wiring harness and connectors leading to the TCM and transmission solenoids.
• Repair or replace any damaged wires or connectors using soldering or appropriate crimp connectors.

4. Transmission Control Module (TCM) Reset

• Reconnect the battery.
• Use the OBD-II scanner to clear the P0700 code and any related codes.
• Perform a TCM reset if required by following the manufacturer’s service manual.

5. Test Drive and Final Checks

• Conduct a test drive to ensure proper operation of the transmission.
• Monitor for any reoccurrence of the P0700 code using the OBD-II scanner.
