DTC Descriptor
DTC C0899: Device Voltage LowCircuit/System Description
The electronic brake control module (EBCM) monitors the battery voltage level available for system operation. A low voltage condition prevents the system from operating properly.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
This fault will be set if the battery voltage to EBCM is less than 10 volts for 200 msec.
Action Taken When the DTC Sets
The ABS indicator turns ON until the voltage returns to above 10 volts.
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 the voltage at the battery terminals.
- With scan tool, read the battery voltage in the EBCM data list.
- Go to Battery Inspection/Test and Charging System Test .
| ⇒ | If less than 10 volts, test the ground circuit of the EBCM for high resistance. If the circuit test normal, test or replace the EBCM. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
