Test B: DTCS C192A, C192B, C192C, C192D and C1933 - Solenoid Actuator Circuit Fault
Pinpoint Test B: DTCs C192A, C192B, C192C, C192D and C1933 - Solenoid Actuator Circuit FaultRefer to Vehicle/Diagrams, Power Steering Controls for schematic and connector information.
Normal Operation
The steering effort control module (SECM) sends voltage to the power steering valve solenoid along circuit CCS11 (GN/WH), the voltage passes through the solenoid and returns to the SECM along circuit CCS12 (VT/GN). The power steering valve solenoid then controls power steering assist by regulating the flow of power steering fluid in the power steering pump. Depending on the returning current, the SECM will be able to detect if the solenoid is functioning correctly.
This pinpoint test is intended to diagnose the following:
^ Wiring, terminals or connectors
^ Power steering valve solenoid
^ SECM
