Hello everyone,
Today I installed JBA shorty headers. After install on test drive I noticed the check engine light on. I also noticed the car would not switch into Hybrid mode at low to no speed. I got back home and checked the code, this is what came up. P0AC4 (Hybrid powertrain control module requested mil illumination), second code after recheck, P0C2B (Auxiliary Transmission Fluid Pump Control Module Feedback Signal). I cleared the codes and will wait to see if they come back. Still ideling for 10 min car would not go into electric mode.
Has anyone else experienced these code, or even put headers on there SUV. Not dicconecting anything but the exhaust manifolds to install the headers, could/would they be the cause of this issue.
Thanks

UPDATE: After clearing the codes, waiting 1/2 hr and restarting the car engine light was back on. I went on a approx 20 mile drive (mixed freeway & street) wathing my drive system graphic. Electric assist does work, Autostop does not. When I got home, I rechecked the codes, and its the same ones. P0AC4 & P0C2B. Going to take it to dealer tomorrow unless someone has experianced this and has a easy remedy.
Thx
