Steering Assist Reduced after dyno tune

Crimson6.2L · January 5, 2020

Two days ago I had my 17 Sierra 6.2 tuned on E85 on the dyno. After pulling it off the dyno it had the ABS Stabilitrac and Traction Control lights showing on the dash from the back spinning and the front not. They all went off after less that 2 minutes of leaving the shop. But every time I start the truck now I get Steering Assist Reduced Drive with Care on the dash. It has no noticeable difference when turning the wheel but shows up as soon as I start the truck. I’ve also removed the battery cables and let sit for 10+ minutes twice now with no change. I did see a thread on the hp tuners forum that it has been a problem when some tables get maxed out in the tune. Is there anything I can do to get it cleared? In the picture that’s as soon as I put the cables back on and turned the key on.

When you turn the engine over does the check engine light stay on?

It is possible a sensor could be damaged or has come loose. Or it may be a fuse.

check your fuse box, Break fluid in the reservoir, make sure you don’t see wires hanging around the wheels near connectors.

look under your driver side frame rail at this cluster *attached. (Electro-Hydrolic control unit) it controls virtually all breaking and stability functions.

make sure Nothing is unplugged or damaged.

start there or just call the tuner.
