I have attached a picture =

the only warning light my SS shows = is the TPMS warning light.

my question is = does the BCM = RCDLR/REMOTE CONTROL DOOR LOCK RECEIVER control the TPMS feature? On my DIC, it doesn't feature the TPMS RE-LEARN process. I have purchased a new set of TPMS SENSORS for my tires, but have yet to install them...

 

The only way to activate the relearn is with a FOB. The instructions are in your Owner Manual (available via the link in my sig). Any instructions you might have found on the internet are wrong.
If this is a 2008 and the battery has been completely drained you might need to have the RCDLR firmware upgraded. Do the pressures display - - - and you can enter relearn but there is no response to letting air out. That indicates the outdated firmware.
That would mean you need updated firmware.

 

I appreciate the speedy response = & will look into the info attached to your sig. At first, only 1 tire showed its pressure, now = no psi #'s show at all on my DIC...


It really grinds my gears to have any type of warning light on = lol...
