Steering Control Module: Description and Operation

CIRCUIT OPERATION
Circuit F83 powers the Speed Proportional Steering Control Module (SPSCM). Circuit Z2 provides ground for the SPSCM.

On circuit S1, the SPSCM supplies 5 Volts to the steering wheel speed sensor. The sensor provides two signals to the SPSCM on circuits S3, and S4. The SPSCM provides ground for the steering wheel speed sensor on circuit S2.

Circuit G7 supplies the vehicle speed sensor to the SPSCM.
