After a car wash today on my Camaro 2012, I got an error that the left rear window can't go up or down. I hear a relay click when pressing the window button. I also noticed that the left front window didn’t work at first but started working after I pushed the button up and down a few times. All this happened when I was about to put the convertible top down with the doors open. I’m not sure if that has anything to do with the error or if it’s related to washing the car. Using my OBD reader, I got these two codes and can’t proceed with further fault reading: IEE AOS GMLAN_LS_33k_Pin1 and IEE AOS GMLAN_HS_PRIMARY_500k_Pin6&1. Any ideas?


OBD Camaro 2012: IEE AOS GMLAN_LS_33k_Pin1 och IEE AOS GMLAN_HS_PRIMARY_500k_Pin6&1



IEE AOS GMLAN_LS_33k_Pin1 (Low-Speed GMLAN at 33 kbps):
Location: The low-speed GMLAN line is often connected to the OBD2 port at Pin 1. In your Camaro, the OBD2 port is typically located under the dashboard, on the driver’s side near the steering column.

• Function: Through this port and Pin 1, diagnostic tools and other modules communicate on the low-speed network.

IEE AOS GMLAN_HS_PRIMARY_500k_Pin6 & Pin1 (High-Speed GMLAN at 500 kbps):
Location: The primary high-speed GMLAN bus uses Pin 6 on the OBD2 port for the positive signal and Pin 14 for the negative signal. In your description, Pin 1 is also mentioned, which may be because certain tests or error codes use Pin 1 as a reference point.

• Function: This high-speed bus connects the ECM, TCM, ABS, and other critical modules and is used for diagnostic communication and control.

 

There are very few (if any at all) 5th and 6th Gen owners on this site. We get very few posts. I this particular forum, no one has posted since June of 2022. “CamaroScotty”, who posted the two “sticky” threads on Electronics/Car Audio in 2010, has not returned to this site since 2018. There is just no traffic in the 5th and 6th Gen forums.
