DTC Descriptor
DTC C0899: Device Voltage LowDiagnostic Fault Information
Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
Ignition 1 Signal | C0899 | C0899 | -- | -- |
Circuit/System Description
The electronic brake control module (EBCM) monitors the ignition voltage level available for system operation. A low voltage condition prevents the system from operating properly.
Conditions for Running the DTC
Ignition is ON.
Conditions for Setting the DTC
This fault will be set if the ignition voltage to EBCM is less than 9 volts for 100 msec.
Action Taken When the DTC Sets
| • | Traction Control System (TCS) and Vehicle Stability Enhancement System (VSES) for the duration of the ignition cycle. |
| • | The TCS indicator turns ON. |
| • | The DIC displays the Service Stability System message. |
Conditions for Clearing the DTC
| • | The condition for the DTC is no longer present. |
| • | The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles. |

Circuit/System Testing
- Measure and record the voltage at the battery terminals. With scan tool, observe the battery voltage signal parameter. Verify that battery terminal voltage and battery voltage signal readings do not differ more than 1 volt.
- Refer to Charging System Test .
| ⇒ | If more than 1 volt, test the battery positive voltage and ground circuits of the EBCM for an open/high resistance or replace the EBCM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

DTC Descriptor
DTC C0899 03: Device Voltage LowDiagnostic Fault Information
Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
Ignition 1 Signal | C0899-03 | C0899-03 | -- | -- |
Circuit/System 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 power steering system has adequate voltage levels to perform the system functions.
Conditions for Running the DTC
Ignition is ON.
Conditions for Setting the DTC
Power steering system voltage is less than 9 volts for at least 1 second.
Action Taken When the DTC Sets
| • | The driver information center (DIC) displays the POWER STEERING warning message. |
| • | No steering assist is provided. |
Conditions for Clearing the DTC
| • | The condition for the DTC is no longer present. |
| • | The PSCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive ignition cycles. |
