Head Scratching P0AC1, P0480, and Sway Bar Awesomeness
2012 4door rubi.
The Background :
So my Sway Bar Disconnect circuit board got all corroded and the sway bar light started flashing about a month ago. At this point I just knew the light was flashing.
I took her wheeling last weekend, and went into some water that completely submerged the disconnect.
After that the dash went a little nuts, flashing all kinds of awesome. So I knew I had an electrical issue.
After a while the prob went away. I checked codes, and only had "Network" codes, and successfully cleared them.
Checked grounds etc, and drove for a while (hours) no problem.
Then the problem returned, and the jeep wouldn't start anymore.
So I lurked the internet and figured out it was the sway bar.
So I tried disconnecting the wiring harness from the disconnect, and the Jeep was able to start and all the electrical weirdness went away.
After all this, I am getting the following codes:
P0480 - Cooling Fan Control Circuit 1.
P0AC1 - Hybrid Battery Pack Current Circuit Sensor "A" Circuit Low
+ several "Network" codes.
When I clear the codes they come right back.
P0AC1 is regarding a Hybrid vehicle from what I can understand....guess only the 12's got this.
I looked at the 60Amp fuse... it looks fine.
The fan comes on, but I can't tell if the fan is high or low; and am unsure how to force it.
The fan is very easy to turn by hand, and keeps turning if I give it a little spin.
I tried removing the sway bar circuit board and cleaning it and reinstalling. I think it is beyond use. The sway light is still flashing, and I can live with that.
I'm about to go on a huge trip covering thousands of miles driving in some desolate areas..... So I'm a little freaked out about this. Leave Saturday morning.
Is is possible that the fan error is just a result of the sway circuit screwing with the CAN?
Will my hybrid battery ever come on and save me gas????
