Hey guys, I'm trying to calibrate the ETS system on my 93 9000 aero.

About a month ago the TCS CTRL light came on, but never caused any issues, then one day I started up the car after a short drive and it was in LHM.

Plugged in the tech 2 and found 4 error codes.

675B0-Permanent
"ETS ECU Fault: Calibration Not Completed"
44261-Permanent
"Speedometer Signal Absent"
24260-Intermittent
"Speed Signal From TC/ABS Absent"
42220-Permanent
"No Voltage To Terminal No. 22 &/Or No. 13"

I cleared all the DTCs, and attempted to calibrate the ETS system in this manner.

Diagnostics>Engine>ETS>Read Values/Activate>Activate

I first select 971 'BASELINE SETTING" and it says 'STARTED', then maybe a 2 or 3 seconds later it says 'FINISHED'.
(on subsequent tries, the tech2 would hang at "started")

I proceed to 973 'CALIBRATION warm up' or something of the sort, but all it has is a selection box for on/off and a bar at the top that becomes solid when I select 'On'. I then start the car, it stumbles turing the first few revs but then goes up to normal idle speed, ~850rpm.

But the TCS CTRL light is still on and I have no sweeping RPM range as described in other calibration procedures I've read online. I key off and out, wait a second or two, and start the process over again.

While the TCS CTRL light is still on, I only have one reoccurring DTC, the
675B0-Permanent, "ETS ECU Fault: Calibration Not Completed" code.

I've gone through the last 3 parts about 4 times with no change.

I'm clearly out of limp home mode, but the ETS system has a problem calibrating. I'm I doing something incorrectly? A different procedure perhaps? if its worth noting, I'm using version 44 of the tech2 software. and low on gas if that matters(in the reserve)

Thanks for your help!!
