Variable Effort Steering Circuit Operation

The Heating and Air Conditioning CONT Fuse in the IP fuse block supplies battery positive voltage (B+) via CKT 41 (BRN) to the variable steering module. The variable steering module is supplied ground from G202 via CKT 150 (BLK).

The powertrain control module (PCM) provides the vehicle speed signal via CKT 817 (OK GRN/WHT) to the variable steering module.

The variable steering module supplies current to the variable steering actuator via CKT 345 (WHT) and CKT 1787 (GRY). As the current supplied to the variable steering actuator is varied, the steering assist is varied.
