C0475 on Cadillac
Electric Steering Motor Circuit
C0475 on Cadillac vehicles indicates electric steering motor circuit. Au7o has documented this code across 1 Cadillac model — most commonly on XTS. This is a General Motors chassis code. The Power Steering Control Module (PSCM) monitors commanded versus actual current in the three-phase electric power steering (EPS) assist motor and sets C0475 when it sees a fault such as an open, a short, motor position outside the allowed tolerance, missing motor sensor trim configuration, or excessive rack travel. When it sets, the module typically shuts down steering assist to protect the circuit, so the steering wheel becomes very heavy while the vehicle remains fully steerable manually. It is seen on GM vehicles with electric power steering, including Chevrolet, GMC, Buick and Cadillac models.
Common Causes of C0475
- •Failed electric power steering assist motor
- •Open, shorted, or chafed wiring in the EPS motor harness
- •Corroded or loose EPS motor connector / poor electrical connection
- •Weak battery, failing alternator, loose battery terminal or bad ground causing low system voltage (EPS needs a stable 9-16V and can draw very high current)
- •Blown power steering fuse or fusible link
- •Faulty power steering control module (PSCM)
