DTC C0561 74

- System Disabled Information Stored Value of Signal Protection Calculation Incorrect

Circuit/System Description

The electronic brake control module (EBCM) receives messages from other modules over GMLAN which are needed to perform antilock brake

system (ABS), vehicle stability enhancement system (VSES), or traction control system (TCS) functions.

Conditions for Running the DTC

* The ignition switch is in the ON position.

* Ignition voltage is greater than 9.5 volts.

Conditions for Setting the DTC

The EBCM receives an invalid message from another module over GMLAN which causes EBCM to deactivate ABS, VSES, TCS, etc.

Action Taken When the DTC Sets

One or more of the following actions may occur:

* The EBCM disables the ABS/TCS/VSES for the duration of the ignition cycle.

* The dynamic rear proportioning (DRP) may be disabled and the Brake Warning indicator may turn ON.

* The Stability Caution indicator turns ON.

* The driver information center (DIC) displays the SERVICE STAB SYS message.

* The DIC displays the TRACTION FAILED message.
