how to fix a P0700 code in Honda Pilot Third Generation (2016-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface.
• Disconnect the negative terminal of the battery to prevent electrical shock.

2. Check Transmission Fluid

• Tools Required: Transmission dipstick, funnel
• Remove the transmission dipstick and check the fluid level. If low, add the appropriate Honda ATF fluid.
• Inspect the fluid condition; if it appears dark or has a burnt smell, a fluid change is necessary.

3. Inspect Wiring and Connectors

• Tools Required: Visual inspection tools (flashlight), multimeter
• Visually inspect the wiring harness and connectors leading to the TCM for signs of damage or corrosion.
• If damage is found, repair or replace the affected wiring or connectors.

4. Test the TCM

• Tools Required: Multimeter
• Using the multimeter, check for proper voltage and ground at the TCM connectors.
• If voltage and ground are present but the code persists, the TCM may need replacement.

5. Replace Transmission Fluid (if necessary)

• Tools Required: Drain pan, funnel, new transmission fluid
• Drain the old transmission fluid and replace it with new Honda ATF fluid, ensuring to follow the correct fluid capacity.
• Replace the transmission filter if applicable.

6. Reconnect the Battery

• Reconnect the negative terminal of the battery securely.

7. Clear Codes and Test Drive

• Using the OBD-II scanner, clear the P0700 code and perform a test drive to confirm the issue is resolved.
