This bulletin applies to 2022-2026 Cadillac Escalade and Escalade ESV vehicles.  Some owners may comment on several warning messages including the ABS MIL, SES Mil, Service Brake System, Service Stabilitrak, or a change in the brake pedal effort. When checking for DTCs, a C055F will be set in the K160 BSCM. The condition typically occurs at temperatures lower than -10 degrees F.  This condition could be caused by a low voltage condition.

If after following normal SI diagnostic and a root cause is not found, perform the following:

1. Test the battery using the GR8/DCBS and replace as necessary. 
2. Inspect the battery, battery cables, engine harness junction/fuse block (X50A) and battery fuse block (X50B) connections to make sure all are clean and tight. 
3. Inspect the K160 BSCM’s power and ground terminals for poor tension, crimps or backing out. Also inspect ground and fuse connections for any loose or corroded connections. 
4. Inspect the charging system for proper operation. 
5. Inspect for any type of aftermarket equipment that could draw the battery down (dash cameras, cell phone chargers, etc.). 
6. Inspect for any parasitic draws on the battery by performing a battery electrical drain/parasitic load test.
