Chevy/GMC/Cadillac Release Fix For 2017 Models With Inoperative Gauges, No Crank or Start Then Stall Condition

[rav3]

Has anyone on here have any of these conditions (in the Title) that GM posted these issues?

I'm curious what fuses they are talking about where it says: "Remove the power feed fuse for the SDGM (F26DL for trucks / F28DL for SUVs). This is a temporary fix and the conditions may return. GM engineering is working for a software correction fix in December 2020."

 

Cause For These Conditions

• Condition #1 may be caused by an error in the serial data gateway module (SDGM) microcontroller. The SDGM can retain power but stop communicating on all CAN channels.
• Condition #1 or #2 could be caused by a SDGM harness with bent, backed out, or loose terminals on the X1 or X2 terminals.

Fix For These Conditions

If a customer is not extremely technically inclined, GM-Trucks.com recommends they take there vehicle to a dealership for repair.

•  Remove the power feed fuse for the SDGM (F26DL for trucks / F28DL for SUVs). This is a temporary fix and the conditions may return. GM engineering is working for a software correction fix in December 2020.
• If removing the power feed fuse does not correct the condition, check and repair damaged, loose, or backed out X1 or X2 terminal connectors.

Now you are considered "extremely technically inclined" if you can remove/reinstall a fuse....
