ECM issues ? ? ?

[Havea Niceday]

Recently purchased a 2007 NBS Silverado and am trying to work my way through some of the issues the previous owner let lapse. My biggest issue, I think, is maybe my ECM. My truck is the WT series V6 so it does not have the DIC buttons nor does it have electric locks/keyless-remote entry. I have a "service TPMS" light & message, Service Airbag light and message, Stabilitrak off light and message , Traction Control off light and message. Additionally my oil life remaining is - - - %. I follow the steps to reset the oil life remaining and it doesnt update. I used a Launch CRP129X to reset the oil life remaining and it does not reset. I follow the directions to put the ECM into TPMS learn mode and nothing happens. I use the Launch CRP129X to enter into the TPMS menu and it will not enter into learn mode. As far as the Stabilitrak and Traction control I have no clue since I do not have those buttons. Is there a way to check on the health status of my ECM to see if it is malfunctioning? Should I flash the ECM and hope for the best? Any suggestions at all to address this would be appreciated.

IS this the stock ECM? Wonder if it's been replaced and maybe not setup properly. I'd check over at scannerdanner.com and ask someone like Tyler or one of the other longtime members. They'd be able to give you some good direction on this. I am a member and use the site frequently.

Another option if you're a tech, owner, etc in the industry is a website called diag.net which helps techs help techs and you get good shop responses.

Have you checked to see that the network is alive? Do you have power, ground, etc on the pins at the OBDII port? You can search YouTube for "checking the CAN network" videos.

Do you have a scope, test light, wiring diagram, etc

I wouldn't be so quick to call a ECM and if programming you're going to need a J-2534 pass thru and a good stable battery maintainer that has very little fluctuation in regards to ripple to give you the best error free environment when programming.

ECM has nothing to do with TPMS for manual resetting.
