Steps 1-4:

DTC C0900

Circuit Description
The Power Steering Control Module (PSCM) has a discrete battery voltage supply circuit. The PSCM monitors the voltage level on this circuit to protect itself against high voltage damage.

Conditions for Running the DTC
The ignition is ON.

Conditions for Setting the DTC
EPS system voltage is greater than 17 volts.

Action Taken When the DTC Sets
DTC C0900 is stored in memory. The IPC message center displays the PWR STR warning message. The PSCM is disabled to protect itself.

Conditions for Clearing the MIL/DTC
- A current DTC will clear when the EPS system voltage returns to less than 15.5 volts.
- A history DTC will clear after 100 consecutive ignition cycles with the EPS system voltage less than 15.5 volts.
- Using a scan tool

Diagnostic Aids
Jump starting the vehicle can cause DTC C0900 to set. If an intermittent malfunction exists, refer to Testing for Intermittent and Poor Connections for further diagnosis.
