VSES Combination Sensor Circuits

Diagnostic Fault Information

Important: Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Testing and Inspection

Circuit/System Description
The electronic brake control module (EBCM) supplies a reference voltage of 5 volts to the yaw rate sensor/lateral accelerometer and the steering wheel position sensor. The sensor supply voltage is monitored via an internal feedback circuit to the EBCM microprocessor.

Conditions for Running the DTC
^ The ignition is ON.
^ Ignition voltage is greater than 8 volts.

Conditions for Setting the DTC
The EBCM detects that the sensor supply voltage is less than 4.75 volts or greater than 5.25 volts for 30 milliseconds.

Action Taken When the DTC Sets
^ The EBCM disables the Traction Control System (TCS)/Vehicle Stability Enhancement System (VSES) for the duration of the ignition cycle
^ The driver information center (DIC) displays the Service Stabilitrak message.

Conditions for Clearing the DTC
^ The condition for setting the DTC is no longer present and the DTC is cleared with a scan tool.
^ The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Circuit/System Testing
1. Ignition OFF, disconnect the yaw rate sensor/lateral accelerometer and the steering wheel position sensor connectors.
2. Ignition ON, measure for 4.8 - 5.2 volts at each 5-volt reference circuits and ground.
^ If over 5.2 volts, test each 5-volt reference circuit for a short to voltage. If the circuits tests normal, replace the EBCM.
^ If under 4.8 volts, test each 5-volt reference circuit for short to ground. If the circuits tests normal, replace the EBCM.
