| 97 Eldo Service airbag help.
My "service airbag" warning and light is on in my cluster. As a result, i dont have use of my info center.(can't check oil life, mpg. etc...) I checked for trouble codes and got two SDM codes: B1155 (SDM calibration mismatch) and, B1159 (Loss of serial data-key not received.) When i reset these codes,(while running engine) the airbag light goes away and i regain use of my info button. If i reset them with the car not running, they go away until i start the car, thats why i reset them usually while i'm driving. Can someone tell me what these codes mean in simpler terms and what i need to do to fix it. Is there a wire loose or diconnected and if so where do i check? Any help would be much appreciated! Thanx! |
