Yes, the rear ABS sensor may be the issue. It has nothing to do with your repair.
A word of advice. Removing the battery cable does nothing. when a code is set, erasing the code does nothing. You need diagnostics and repairs done before the system will reset. The ABS system does not need to be reset. If your repair is correct, the light will go out by itself when you get to 8 MPH after the repair. If the light does not go out, then the repair was not correct.
The 561 is a result of the 45 code. Once the sensor is replaced, then both will go inactive.
1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle (See: Vehicle Lifting > Procedures > Lifting and Jacking the Vehicle).
2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (See: Wheels and Tires > Removal and Replacement > Tire and Wheel Removal and Installation).
3. Disconnect the wheel speed sensor electrical connector (1).
4. Release the wheel speed sensor wire harness grommet (2) from the lower control arm bracket.
5. Release the wheel speed sensor wire harness routing clips (3) from the upper suspension link.
Perform the Diagnostic System Check - Vehicle (See: Vehicle > Initial Inspection and Diagnostic Overview > Diagnostic System Check - Vehicle) prior to using this diagnostic procedure.
Review Strategy Based Diagnosis (See: Vehicle > Initial Inspection and Diagnostic Overview > Strategy Based Diagnosis) for an overview of the diagnostic approach.
Diagnostic Procedure Instructions (See: Vehicle > Initial Inspection and Diagnostic Overview > Diagnostic Procedure Instructions) provides an overview of each diagnostic category.
DTC C0561 71
System Disabled Information Stored Invalid Serial Data Received
DTC C0561 72
System Disabled Information Stored Alive Counter Incorrect
DTC C0561 74
System Disabled Information Value of Signal Protection Calculation Incorrect
The electronic brake control module (EBCM) receives serial data messages from the body control module (BCM), engine control module (ECM), instrument panel cluster (IPC), and the transmission control module (TCM) 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
Ignition voltage is greater than 10 volts.
Conditions for Setting the DTC
The EBCM receives an invalid serial data message from another module.
Action Taken When the DTC Sets
The EBCM disables the traction control system (TCS)/ vehicle stability enhancement system (VSES).
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 100 consecutive drive cycles.
This DTC indicates that there are no problems in the EBCM. The BCM, ECM, IPC and the TCM should be checked for a possible fault.

1. With a scan tool, view the Invalid Signal Data Display.
2. If no invalid signal are present, view Signal Fault Data in the Enhanced DTC Data.
3. Refer to appropriate module for diagnosing the invalid message data.
4. Do not replace the EBCM due to this DTC fault.
