DTC C0561
The electronic brake
control module (EBCM) disables the traction control when other electronic
control modules set DTCs for components that effect the operation of the
Traction Control System (TCS).
This diagnostic procedure
supports the following DTC:

Conditions
for Running the DTC
|
• |
The
ignition is ON. |
|
• |
Ignition
voltage is greater than 8 volts. |
Conditions
for Setting the DTC
The powertrain
control module (PCM) or body control module (BCM) diagnoses a condition
preventing the engine control portion of the traction control function and
sends a serial data message to the EBCM indicating that torque reduction is not
allowed. The PCM or BCM will typically set a DTC and the EBCM will set this
DTC.
Action
Taken When the DTC Sets
|
• |
The
EBCM disables the TCS until the DTC becomes a history DTC. |
|
• |
The
Traction Off indicator turns ON. |
|
• |
The
Antilock Brake System (ABS) remains functional. |
Conditions
for Clearing the DTC
|
• |
The
condition for 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. |
This DTC is for
information only. As an aid to the technician, this DTC indicates that there
are no problems in the ABS/TCS system.
