Are you getting any other symptoms along with the c0561? Most of the time when I see this code it is usually just indicating a problem with another system.

Does your scan tool read fuel trims?

we do have a scanner that will read that, but the code c0561 - 071 is for serial # read error telling us a problem with ecbm, tcm, ecm, bcm etc. something like that.

Several modules can send data messages to the Electronic Brake Traction Control Module (EBTCM) making it turn on the traction control and/or stabilitrac lights. I always treat this C0561 code like it is another module telling the EBTCM there is a problem somewhere else.

Hook the scan tool up and look for high or low fuel trims. Anything higher than 10 or lower than -10.
