Hey guys,

Looking for some opinions. I recently installed headers and after the install I get a service Stabilitrak message and a power steering message if in a tighter turn, but only turning left and, from what I can tell, some input on the throttle. I pulled DTCs and have found a loss of comm with the steering angle sensor and ABS. If anyone has seen this before, I'm wondering if you had to just reprogram the sensor or replace the whole thing? Thanks!

Yeah, I found a wiring harness was rubbing against the headers. Once the insulation burnt away the wiring was shorting on the header

[2017Zl16spd]

Which wiring harness? Anyway you can show me? Im bummed i barley saw this

[ChillaxAttack]

Unfortunately, I no longer have the vehicle so I can't show you, but it should be on the left side of vehicle.

When turning left the harness got pushed right toward the header until it made contact. Hope that helps

The one I know that can be an issue is underneath the coolant tank. Do a search on here it's a common thing.

Figured It Out Thanks To Both Of Yall! It Was The One Under The Coolant Tank! I Just Couldnt See It. It Burned Up The Insulation And The Cables Were Visible But Not Damaged At All. Zipties And Tape 5$ Spent.

I have seen a lot of issues with headers damaging wire harnesses on the forum.
