Abs light on, cruise control and engine light 2007 subaru outback

you have a code set in one of the computers that needs to be checked to know what has to be done to fix.

I found this under Fixya; 2006 Subaru Outback; there were 25 answers: The problem is not with an emission issue as you would expect with a check engine light. The ER 55 code on the odometer means that there is a loss of communication with the ECU, that is why the check engine light is on and cruise light flashing. for what ever reason whenever your check engine light comes on the cruise becomes disabled. Lame I know. I work in the service department and have seen this issue a lot. The only real way to fix this issue is to go the dealer and have them do a reflash for your vehicle. If the ECU is bad it is covered under the federal emmission wrty for 8 years or 80,000 miles

The clue is the Check Engine Light (CEL). Get the ECU read for the error code(s). The Cruise light turns on when the ECU detect any error.

It may be as simple as a gas cap that is not tight enough.

you have a dry joint or damaged wheel sensor, and the only way to find it is 1 at a time until you find it, these lovely little items effect all your problems mentioned

P0420 Usually indicates a bad catalytic converter or a bad oxygen sensor. Since you car is 2008 my money is on the oxygen sensor. Or it could be something as simple as an exhaust leak. The cruise control will keep flashing until you get the CEL fixed

car threw a CEL at me with ER 55 and blinking cruse. the error code went away after a 5-6 restarts,dont worry it´s not a serious proplem.

I had this occur on my 2007 Subaru Tribeca. ABS, Traction Control, Check Engine lights were solid, Cruise Control light was blinking and "Er SS" (commonly misread as Er 55) displayed on Trip Odometer. All lights were cleared after 10 or so miles. It appears this is a Speed Sensor (SS) reading error whereby the computer notices an irregularity with the readings taken from the four wheels. Most often it is a temporary and harmless glitch and sometimes a result of debris that is impeding the sensor's reading at one of the wheels.

An addition to my previous post (after talking to my husband more). Three of our wheels were snow packed. Not the wheel wells, but the inside of the wheels. He thinks that this is what caused the problem. The ABS sensors are located there. Having them encased in snow was likely what caused this condition. Solution = clean all the snow off your tires -- and the problem should go away. Sounds like the problem is moisture gets into the ABS sensor or something shorts out with the communications to those sensors.
