Problem report from OnStar
Got my monthly OnStar diagnostics report in on Thursday showing some problems (see attached). Two of the items don't apply to the C7 (hybrid powertrain system and 4WD), so I ran a scan on my OBD code reader with Torque Pro app and it shows this result:
Test Results:
MID $41 TID: $94
O2 Heater Monitor Bank 1, Sensor 1
Min 26816
Max 40920
Current 65520
MID $30 TID: $b3
(no description)
Min 26928
Max 12289
Curr 65520
I ran this test three times over two days and got the same result each time, and a Google search on the codes above wasn't helpful. There have been no CELs and the code reader reports no trouble codes stored in the ECU. OnStar won't give additional info since I'm no longer subscribing. Does anyone have any idea what's going on here? Will be calling the dealer tomorrow but wanted to throw this out here first.
