That error is from the Power Steering ECU and indicates that it lost comm with the ECM.

If you have any devices that you regularly leave plugged into the diagnostic connector, the error could be due to that device squawking a bit too much on the CAN bus.

Hi guys, I got the same error code in my car, but the P/S light never turned on, it does turn on at ignition which means the light is good.

I keep the diagnostic connector empty so that is not my issue. I have a BlueDriver OBD tool and it said that a common fix is to clean the battery contacts and replace the cable terminals. Will give a try.

Do you have any other suggestion?
