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

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, transmission fluid, funnel.
• Disconnect the negative terminal of the battery to ensure safety before starting any work.

2. Inspect and Replace Transmission Fluid

1. Locate the transmission dipstick or fill plug and remove it.
2. Using a funnel, add the appropriate type of transmission fluid (consult owner’s manual for specifications) until the correct level is reached.
3. Check the fluid condition; if it appears burnt or contaminated, a fluid change may be necessary.
4. If changing fluid, drain the old fluid from the transmission pan and replace with new fluid as specified.

3. Inspect and Repair Wiring

1. Visually inspect the wiring harness connected to the TCM for any signs of wear, fraying, or corrosion.
2. Use a multimeter to check for continuity in the wiring; repair or replace any damaged wires as necessary.
3. Ensure all connectors are securely fastened and free from dirt or moisture.

4. Test and Replace TCM (if necessary)

1. If the TCM fails the voltage and ground tests, consider replacing it.
2. Remove the old TCM by unscrewing it from its mounting location.
3. Install the new TCM and torque the mounting bolts to the manufacturer's specifications.
4. Reconnect all wiring and connectors securely.

5. Reset Error Codes

1. Reconnect the battery terminal.
2. Use the OBD-II scanner to clear any stored error codes.
3. Perform a test drive to verify if the P0700 code returns.
