DTC Descriptors
DTC C0292 07: VSES Combination Sensor Circuit Voltage Above or Below Threshold
Circuit/System Description
The electronic brake control module (EBCM) supplies a ignition voltage to the yaw rate sensor/lateral acceleration sensor, and the steering angle sensor. The sensor supply voltage is monitored via an internal feedback circuit to the EBCM microprocessor.
Conditions for Running the DTC
• | Ignition voltage is greater than 10 volts. |
Conditions for Setting the DTC
The EBCM detects that the sensor supply voltage level is less than 4.75 volts or greater than 5.25 volts.
Actions Taken when the DTC Sets
• | The EBCM may disable antilock brake system (ABS), traction control system (TCS), and StabiliTrak 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 the DTC is no longer present. |
• | The EBCM clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles. |

Circuit/System Testing
- Ignition ON, verify that DTCs U1826, U1827, or C0292 are not set.
- Ignition OFF, disconnect the yaw/lateral acceleration sensor connector.
- Ignition OFF for 5 minutes, test for less than 10 ohms between the low reference circuit terminal 6 and ground.
⇒ | If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuits test normal, replace the EBCM. |
- Ignition ON, test for 11.75-12.25 volts between the 12-volt reference circuit terminal 1 and ground.
⇒ | If less than the specified range, test the 12-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM. |
⇒ | If greater than the specified range, test the 12-volt reference circuit for a short to voltage. If the circuit tests normal, replace the EBCM. |
- If all circuits test normal, replace the Yaw Rate/Lateral Acceleration Sensor.
