Can you confirm if you've done the config that is somehow activate the OAT sensor in the IPC? I recall one time when I retrofitted UHS cluster and activate the OAT sensor in the IPC, it cause ambient temp to stopped working, so I ended up disable OAT sensors and it went back to normal.

I did literally nothing. It’s possible OAT on IPC was activated on previous vehicle. Do you think that is possible somehow turn off OAT in IPC and it will work and display ambient temperature from ECU? Because sometimes the temperature value blink instead ”—“ and immediately disappears.

use GDS2

Thank you I tried and unfortunately this didn't help. Temperature from ECU is ok but on IPC is wrong.

I dont have access to the CAMARO SI (service information) maybe someone can share the schematics.

 

In insignia A the sensor goes to the pins 27 and 25 (udd and uhs). check in your connector if you have this wires

Hi,

You can support me schematic of control s78 in ipc UHS?

Thanks you, because i see video then may be control by old button in signal (my car is 2011 then button on right is media control)

this uses a stalk2lin adapter to work

There's a parameter in the IPC configuration called "OnStar region." Changing it also changes the algorithm for processing temperature sensor readings. It makes the display +10 or -10% relative to the actual readings, etc.

Hi, You can help me connect pinout of media button. I buy it and see it have 10 pin out

Hi everyone,

Does anyone have the pinout for the Bose T3 amplifier for the 2016 Camaro? Part No.: 23394114

There seem to be differences in the speaker configuration.
