Some owners of 2014-2016 Cadillac XTS vehicles may comment on a Service Power Steering message displayed on the DIC (driver information center) after a cold start. This condition may be intermittent. When checking for DTCs, the power steering control module may report C056D 3C, C0475 00 or the BCM may report a U0131 set as current or in history.

1. Inspect the G111 ground and the 80A F72UA fuse for proper connection. Make sure that the ground is free of paint and both connections are tight. Tighten the G111 ground to 80 in-lb. Tighten the F72UA fuse to 42 in-lb.
2. Fully charge the battery using the GR-8 tool.
3. Reprogram the power steering control module with the latest calibration available on TIS2WEB.

Check tightness of the 80A F72UA fuse.
