C0899

Steps 1-10:

DTC C0899

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 voltage is less than 8 volts

Action Taken When the DTC Sets
- DTC C0899 is stored in memory.
- The IPC message center displays the PWR STIR warning message.
- No steering assist is provided.

Conditions for Clearing the DTC
- A current DTC will clear when EPS system voltage is greater than 8.65 volts.
- A history DTC will clear after 100 consecutive ignition cycles with the EPS system voltage greater than 8.65 volts.
- Using a scan tool

Diagnostic Aids
The scan tool can be used to view the number of times a low battery incident has occurred. If an intermittent malfunction exists, refer to Testing for Intermittent and Poor Connections for further diagnosis.

Test Description
