what does code P0700 mean for my Tesla Outback 5th Generation (2015-2019)?

Solution

• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

2. Check fluid level; add the appropriate fluid type if low.
3. If fluid is dark or contaminated, proceed to replace it.
   • Tools Required: Socket set, fluid pump
   • Fluid Type: Refer to the owner’s manual for the correct type of transmission fluid.
4. Drain the old transmission fluid from the pan and replace with new fluid.
5. Reinstall the dipstick or fill plug securely.

3. Repair or Replace Wiring/Connectors

1. Visually inspect the wiring harness and connectors related to the transmission control module.
2. Repair any damaged wires or replace faulty connectors.
   • Tools Required: Wire strippers, soldering iron, heat shrink tubing
3. Ensure all connections are secure.

4. Test Transmission Control Module

1. Reconnect the battery and start the engine.
2. Using a multimeter, check the voltage and ground signals at the transmission control module.
3. Follow any specific testing procedures outlined in the service manual for the module.
