Front impact sensors
Just picked up a 2009 Civic LX-S automatic with 149,000 miles for a commuter yesterday. No cel or srs lights on the dash and both work but do have a tpms light on.
I scanned all modules with my blue driver obd scanner and got no signal from front left and front right impact sensors. 41-11 and 41-12 I think? As well as the weight sensor on drivers side front seat is also giving me a code but the srs light is off.
I looked under the front bumper and saw both impact sensors mounted and plugged in. Airbag recall was done at the Honda dealer. Car was totaled on way to first dealer before it was ever first sold, very minor repair, I can see the repair and believe it was totaled because it was a new car not because it was bad.
any ideas on getting the front impact sensors to work? Wiring looks good and they are plugged in tightly. I was reading and searching that they can fail, can i just unplug and bolt in a new one after having the battery disconnected for 30-60 minutes? Can’t clear the code because until i get signal from impact sensors.
thanks!

Re: Front impact sensors
You might want to contact with BlueDriver tech support
This seems to be a specific issue between BlueDriver and Honda, especially for code 41-11.
Here is a reply that I got from BlueDriver support - just a quick FYI:
"For the impact sensor code he is partially right - there's no rule of thumb that codes starting with 4 can be ignored, but this specific one probably can - it seems to come up on the majority of Honda's, we've found that many scan tools will not display it, or won't even scan the system it comes from (some even lie and claim they did, but didn't) - but it doesn't seem to be an actual problem."
