The electronic brake control module (EBCM) monitors the voltage level available for system operation. A low voltage condition prevents the system from operating properly.
Ignition is ON.
This fault will be set if the ignition voltage to EBCM is less than 9 volts for 100 msec.
• | Traction Control System (TCS) and Vehicle Stability Enhancement System (VSES) for the duration of the ignition cycle. |
• | The TCS indicator turns ON. |
• | The DIC displays the Service Stability System message. |
• | 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. |

⇒ | If the greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal replace the EBCM. |
⇒ | If greater than the specified value , test the ignition voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal replace the EBCM. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

The rear differential clutch control module (CCM) monitors the voltage level available for system operation. A low voltage condition prevents the system from operating properly.
Ignition is ON.
This fault will be set if the voltage to CCM is less than 9 volts for 100 msec.
One or more of the following actions may occur:
• | All Wheel Drive Off (AWD Disabled). |
• | Service All Wheel Drive (Service AWD). |
• | The condition for the DTC is no longer present. |
• | The DTC is not detected in 40 consecutive drive cycles. |

⇒ | If more than 1 volt, test the battery and ground circuit of the CCM for low voltage input or high resistance in the ground circuit. If the circuit test normal, test or replace the CCM. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
