Fault Condition: The ABS Status code will set when the EMS Module has lost the ABS Status Signal from the ABS ECU.

Possible repairs:

If communication can be made with the ABS ECU, and there are no other codes, go to the Trouble Shooting Procedure for the ABS ECU.
If there is NO communication with the ABS ECU via the diagnostic tool, go to the Trouble Shooting Procedure for the Data Lines.
