- Brake Boost Solenoid Valve Circuit Shorted
Circuit/System Description
The electronic brake control module (EBCM) uses input from the boost pressure sensor for more accurate control during brake and vehicle stability
enhancement system (VSES) event. The boost pressure sensor is internal to the brake pressure modulator valve (BPMV).
Conditions for Running the DTC
* The ignition is ON.
* Ignition voltage is greater than 10 volts.
Conditions for Setting the DTC
C012F 00, C12A7, C12DC
Solonoid feedback current greater than 25% of commanded current.
C012F 0E, C12DD
Solonoid feedback current greater than 50% of requested current.
Action Taken When the DTC Sets
* The EBCM disables the ABS/traction control system (TCS)/vehicle stability enhancement system (VSES) for the duration of the ignition
cycle.
* A DIC message and/or a warning indicator may be displayed.
Conditions for Clearing the DTC
* The condition for setting the DTC is no longer present.
* The EBCM clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.

DTC Descriptor
DTC B1424 00
- Device Voltage Low - Theft Deterrent Module
Diagnostic Fault Information
Circuit/System Description
The theft deterrent module (TDM) monitors the battery positive (B+) voltage available to it. If the voltage at the TDM is between 6-9 volts, and the
voltage being reported by a serial data message is greater than 9 volts, then DTC B1424 00 sets.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
* Voltage at the TDM B+ circuit is between 6-9 volts.
* Reported battery voltage received via serial data is valid and is greater than 9 volts.
* The above conditions have been met for 2 seconds.
Action Taken When the DTC Sets
* The security indicator turns ON.
* The driver information center (DIC) displays the SERVICE THEFT DETERRENT SYSTEM message.
Conditions for Clearing the DTC
* A current DTC clears when the battery voltage at the TDM is greater than 9 volts, or if the voltage reported by serial data is less than 9 volts.
* A history DTC clears after 100 consecutive ignition cycles, if no failures are reported by this diagnostic.
Diagnostic Aids
A low voltage DTC in multiple modules indicates a concern in the charging system.
