Re: Code C1282 / Yaw sensor voltages (NelsonV98Vert)
BTW, I had the console and most of the dashboard disassembled just before I got the codes. Also, when the codes started, I was driving around without the AH/TCS console switch plugged in.
When the problems started, I got Service Active Handling and Service Traction Control . After I plugged the console switch back in, Service Traction Control went away, but Service Active Handling remains.

Oh OK, I got that. How does one proceed without a scan tool or other Pinout boxes? Am I stuck going to the dealer?
I am afraid I might have "tripped" over something and don't want to have to pay the dealer big bucks if they find I caused something not covered by GMPP. Otherwise, I'd let them have at it.

Wt99C5-
In the print you sent me, the diagram shows wiring between the yaw rate sensor and EBCM. The numbers along side the wiring (P200, C102, 1056) look like interface or connector points; do you know where those are located, as well as the EBCM?

The yaw sensor is located in the lower left side of the console. The EBCM / EBTCM is mounted on the steering rack, drivers side. Most of the flow is just measuring resistance. The voltage readings from your earlier post are the same points as what the flow calls out. If you were working in this area, re-trace your steps, look for a short, cut or smashed wire.

Re: Code C1282 / Yaw sensor voltages (NelsonV98Vert)
I measured the voltages at the yaw sensor:
Grey: 5.1V
Blue: .05V
Orange: .05V
Does this sound right? If so, if not, what next?
Grey: 5.1V
Blue: .05V
Orange: .05V

Between gray and orange you should read 4.75 to 5.25 v.
Between orange and blue it should read 2.35 to 2.65 v.
Turn the key on, but donÂ’t start the engine. 0 yaw rate = 2.5 v
If it is 0v replace the yaw rate sensor.
Check the pins on the sensor first.
Check the blue wire, is it cut or damaged?
BTW don t use the gray wire for a supply line for a stereo system.

Re: Code C1282 / Yaw sensor voltages (Wt99C5)
I didn't get a chance to look again last night - had Bible study. And tonight I have a retirement dinner to attend, but I'll poke around tomorrow. But a new thing happened last night. . .
I haven't driven the car much since these codes began appearing; my office is only four miles away. Last night on my way to Church (about 18 miles), I got Service Vehicle Soon and C1283 C and C1284 C.This morning, I checked my codes again: C1282 is still current, but C1283 and C1284 are History codes.
Thanks for now. I'll keep you posted.

Go back to your original voltage readings.
Between gray and orange you should read 4.75 to 5.25 v.
Between orange and blue it should read 2.35 to 2.65 v.
Turn the key on, but don’t start the engine. 0 yaw rate = 2.5 v

Any idea what a Yaw rate sensor costs (P/N?)? My GMPP deductible is $100 a pop.
