Onstar found a code C0760 in BCM, where to go from here?

[dutch724]

I have been trying to figure out why when I try to add apps to my on screen display the install fails. I finally got Onstar on the line to figure it out. They did a scan and found that my BCM has a code C0760 no other numbers than that. I really don't want to run down to the dealer for them to charge me $150 to tell me that its TPMS sensor. I don't have any lights on my dash that tells me something is wrong. A little over a year ago I replaced one of the TPMS sensors. I don't think the BCM would hang on to that code and cause issues now seeing this is a recent issue with the on screen apps.

Has anyone had experience with this issue? Please point me in a direction that I can go to get answers.

Left Rear Low Pressure Sensor. 

 

Scroll through your screens and fine the TPMS display. Is one out? If not then it was not reset when that sensor was replaced in that position thus an old code. Clear it.  If it's out...replace it. 

 

Type your codes into Google and BOOM there's your answer. (most of the time)

In most circumstances you would be correct. But what "screen"? I have no nothing on my end that tells me there is an issue. ONStar did the scan and then emailed me the results. I have no pressure check light on in the dash. As far as I can see all my TPMS are working by giving me the pressures in all 4 tires.

This is why I'm not quite sure what is going on.

Do you have any devices plugged into your OBD port?  Any aftermarket LED lighting, anything in your 12v outlets, any building access key tags, etc?  

 

Did OnStar give you the symptom bite on that code as well?  There are 3 symptom versions for C0760.

 

DTC C0760 03

Left Rear Tire Pressure Sensor = Low Voltage

DTC C0760 29

Left Rear Tire Pressure Sensor = Too Few Pulses

DTC C0760 39

Left Rear Tire Pressure Sensor = Internal Malfunction

 

Makes me also wonder if there are more codes...Do you have a code reader that can read ALL vehicle modules?  Blue Driver and OBDLinkMX are two that can can read ALL modules and pull pending, current and history codes for ALL modules.
