SRS Light Affecting Center Console Buttons

[mandieb]

My 2019 Ranger had the SRS light come on at 127k miles. When the light is on, my temperature read out stops working and so do all the buttons and dials on the center console (volume, tune, air temperature and flow, EVERYTHING!) The blinker lights blink extremely fast and my passenger blind spot detector is stuck on. Has anyone else had this problem? My mechanic has never seen this before.

I suspect shorted BLIS Module (R/R)
This circuit is on the MS-CAN network, and I believe its shorting the bus.
It can be anything on the network, but with the BLIS module (moisture-intrusion) being highly suspect, I would start there.
Inspect the housing for moisture and then disconnect the R/R taillamp assy, and note any change in the FCIM.
It may require a wiring check, but I have a hunch the BLIS module is the most likely cause.

Tail lights had 6in of water in them…so 100% moisture intrusion! Thank you so much airline tech!
Was backing into snowbanks all winter to load and unload my snowmobile. I must have cracked them doing that.
