Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal.
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.
If the fluid is dark or has a burnt smell, drain the transmission fluid using a fluid pump or by removing the drain plug.
Replace with fresh Honda ATF-Z1 or DW-1 fluid.

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.
