Sounds like the code does point to your reported symptoms.I have a problem with my CRV 2009, when I driving and I stop (one time or two at day) the car shutdown and I have to start one againt. I scanner the ECU, and give me the error code P0685. Please help me!
This link explains the particular code, which is a standard OBD-II code. Skip past all the mechanics sales pitch and read the explanation farther down the page. https://www.yourmechanic.com/articl...relay-circuit-malfunction-by-valerie-johnston
Forum members are pretty good about providing troubleshooting advice.. so be patient for other forum members to get a chance to read and who may be able to give you CRV specific advice.
