Object Number: 1198155 Size: MF

Circuit Description

The Power Steering Control Module (PSCM) has a discrete battery positive voltage supply circuit. The PSCM monitors the voltage level on this circuit to ensure the Electric Power Steering (EPS) system has adequate voltage levels to perform the system functions.

Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

EPS system battery voltage is 9-11 volts.

Action Taken When the DTC Sets
    • DTC C0896 is stored in memory.
    • The IPC displays the SERVICE VEHICLE SOON warning indicator.
    • Steering assist is reduced.

Conditions for Clearing the DTC
    • A current DTC will clear when EPS system voltage is greater than 11 volts.
    • A history DTC will clear after 100 consecutive ignition cycles with EPS system voltage greater than 11 volts.
    • Using a scan tool
