Solution

1. Preparation

• Gather necessary tools and parts.

• Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Check and Replace Transmission Fluid

• Remove the transmission fluid dipstick and check the fluid level.
• If low, add the appropriate Honda ATF-Z1 or DW-1 fluid until it reaches the full mark.

3. Inspect and Repair Wiring

• Examine the wiring harness connected to the TCM and transmission.
• Repair any frayed or damaged wires and ensure that all connectors are secure.
• Use electrical contact cleaner to clean any corroded connections.

4. Test and Replace Transmission Control Module (if necessary)

• If previous steps do not resolve the issue, perform a bench test on the TCM.
• If defective, replace the TCM with a new or remanufactured unit.
• Reconnect all wiring and connectors.

5. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear any stored codes, including P0700.
• Start the vehicle and allow it to reach operating temperature.
