DTC Descriptors
DTC C0899 00
- Device Voltage Low - EBCM (w/o JL4)
DTC C0899 03
- Device Voltage Low - EBCM (JL4)
Diagnostic Fault Information
Typical Scan Tool Data
Circuit/System Description
The electronic brake control module (EBCM) monitors the battery positive (B+) 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
The ignition voltage available to the EBCM is less than 9 volts for 100 msec.
Action Taken When the DTC Sets
* The traction control system (TCS) and vehicle stability enhancement system (VSES) are disabled for the duration of the ignition cycle
* The vehicle dynamics caution (VDC) indicator turns ON.
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.
