how do I fix the P0700 code in my Tesla Outback 5th Generation (2015-2019)?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent any electrical issues.

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Remove the transmission fluid dipstick and check the fluid level. If low, add the appropriate transmission fluid as specified in the owner’s manual.
  2. If the fluid appears dark or has a burnt smell, consider a full fluid change.
  3. To change the fluid, locate the transmission pan, remove it, and replace the filter. Reinstall the pan with new gasket and fill with new fluid.
• Tools Required:
  • Socket set
  • Transmission fluid pump
  • New transmission fluid
  • New filter and gasket

3. Inspect Wiring and Connectors

• Sub-steps:
  1. Visually inspect all wiring harnesses and connectors leading to the TCM for signs of wear, damage, or corrosion.
  2. Clean any corroded connectors using electrical contact cleaner.
  3. Tighten any loose connections to ensure proper communication between the TCM and the transmission.
• Tools Required:
  • Electrical contact cleaner
  • Multimeter for continuity testing

4. Test Transmission Solenoids

• Sub-steps:
  1. Access the transmission solenoids based on the vehicle’s service manual.
  2. Disconnect the electrical connectors from each solenoid.
  3. Use a multimeter to measure the resistance of each solenoid; compare readings to the specifications in the service manual.
  4. If any solenoid is out of specification, replace it.
• Tools Required:
  • Multimeter
  • Socket set for solenoid removal

5. Reconnect Battery and Clear Codes

• Reconnect the battery.
• Use the OBD-II scanner to clear the P0700 code and any related codes.
• Confirm that the check engine light is off.
