how do I fix the P0700 code on my Honda Civic 9th Generation (2012-2015)

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, fluid pump, and a container for old fluid.
• Ensure the vehicle is on a level surface, and engage the parking brake.
• Disconnect the battery to avoid electrical shorts.

2. Check and Replace Transmission Fluid

1. Locate the transmission dipstick tube and remove the dipstick.
2. Insert a fluid pump into the transmission pan drain plug to drain old fluid into a container.
3. Replace the drain plug and refill the transmission with the correct type of transmission fluid (refer to owner’s manual for specifications).
4. Start the engine and let it idle in park; check fluid level using the dipstick and add fluid as necessary.

3. Inspect and Replace Transmission Control Module (if necessary)

1. Remove any necessary components to access the TCM (refer to the service manual for specific instructions).
2. Disconnect the electrical connector from the TCM.
3. Remove the mounting bolts and take out the old TCM.
4. Install the new TCM by reversing the removal steps. Torque bolts to the manufacturer’s specifications.
5. Reconnect the electrical connector securely.

4. Check Wiring and Connectors

1. Inspect all wiring harnesses connected to the transmission and TCM for signs of wear, fraying, or corrosion.
2. Repair or replace damaged wires and ensure all connectors are tight and free of dirt.
