I replaced the VTM-4 fluid about 10 days ago. The Pilot has 20,000 miles. Now the check engine light came on and my wife thinks the VTM-4 light came on as well while driving but it's not on now (but the check engine light is still on). I want to read the code for the check engine light but can't figure out how. I have the service manual but couldn't find the procedure anywhere (it's not under check, engine or light in the index).
