Hi guys,
yesterday my Accord developed strange issue - when I put it in reverse gear, engine stops running for a split second and after that everything comes back to normal. Also radio turns off and I can hear fuel pump restarting again. It also happens when engine is off but ignition on - same again, radio turns off for a split second and lights on dashboard flashes (in this occasion check engine light)
Check engine light is on and the fault is P0685 - ECM/PCM power relay - circuit open
Last year my mechanic replaced alternator and caused some shortcut cause I have had to replace drivers door control panel as it stopped operating and I couldnt open door. I wonder if it is anything to do with this...
What should I be looking for? WHat could cause it? Car runs ok, all other gears works fine.
Could it be faulty ECU?
Here you can watch how does it look like when I put gear in reverse: https://streamable.com/a4ctr2
