ASR is a very complicated system. You really need to get a shop manual and follow the troubleshooting section in it.

Thanks
My guess is the "adjuster assembly" is the motor connected to the accelerator cable under the hood. It is just in front of the brake master cylinder. The purpose of the adjuster is to relax the throttle, even if your foot is pushing it down, and decrease engine torque during a loss of traction.

I start the car and everything is fine as soon as I hit the gas pedal ASR light comes on and H65 is thrown.

Or you can do what I did. Rip the system out of the car.

There is a setup procedure in the shop manual on how to adjust this.

My guess is, once you set it up correctly, it will be fine.
