what does it mean if my Honda Pilot YF3 (2016-2022) has a P0700 code

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Ensure the vehicle is on a level surface and securely supported.

2. Check Transmission Fluid

• Remove the transmission dipstick (if equipped) and check fluid level.
• If low, add the recommended transmission fluid (Honda ATF DW-1).
• Inspect fluid color and smell; if dark or has a burnt odor, a fluid change may be necessary.

3. Inspect Wiring and Connectors

• Locate the TCM and visually inspect its connectors.
• Disconnect the TCM connector and check for corrosion or bent pins.
• Clean connectors with electrical contact cleaner, if necessary.

4. Test Transmission Control Module

• Using a multimeter, check the voltage at the TCM connectors as per the service manual specifications.
• If the voltage readings are out of range, consider replacing the TCM.

5. Clear Codes and Road Test

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the P0700 code and any other related codes.
• Conduct a road test to ensure the transmission operates smoothly and verify that the check engine light does not re-illuminate.
