what does it mean when my Tesla Outback 6th Generation (2020-2024) shows a P0700 code

Solution

1. Preparation

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

2. Check Transmission Fluid

• Tools Required: Transmission fluid dipstick, funnel
• Remove the transmission fluid dipstick and check the fluid level. If low, top off with the manufacturer-recommended fluid type.
• Inspect the fluid for burnt odor or metallic particles; if present, a transmission service may be required.

3. Inspect Wiring and Connectors

• Tools Required: Multimeter, socket set
• Visually inspect the wiring harness and connectors to the TCM for any signs of damage or corrosion.
• Use a multimeter to check for continuity and proper voltage at the TCM connections.

4. Test the TCM

• Tools Required: Multimeter
• Follow the vehicle’s service manual to perform a diagnostic test on the TCM.
• Check for proper input/output signals according to specifications. Replace if faulty.

5. Repair or Replace Affected Components

• If any faulty sensors or wiring are found during inspection, replace them according to manufacturer specifications.
• Use a torque wrench to ensure any bolts or connectors are tightened to the recommended torque values.
