C1110 Nissan -

Question

I have 2004 Nissan maxima se, about a month ago when the rain is so heavy, I have notice that when I step into the brake, the ABS kicks in, now the light on ABS and Emergency Brake turns on and off. if the light is on the abs wont kick in but if the light is off, the abs kicks-in. Yesterday, I bring it in to Nissan dealership to a diagnostic and the service advisor said that it was scanned for codes and the controller failure (C1110) and actuator relay (C1140) found that there is a erratic signal from the right rear abs sensor. he said the first step would be to replace the sensor/hub and re-test to make sure no damage was done to the abs actuator and it said that it might need a ABS Actuator if problem still exist. please help.
