isiginamo Posted October 31, 2007 Share Posted October 31, 2007 I think this is just a method of checking HVAC system... but this is what my car did. It displayed a number 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, then back to 20... over and over and over. And that is all? Does it mean anything? Thanks alot!

gordonw Posted October 31, 2007 Share Posted October 31, 2007 20 is for the solar sensor circuit. 21,22,23,24 is for the ABS actuator solenoid circuit. No clue on the other codes. Quote Link to comment Share on other sites More sharing options...

Happy Halloween I have to shine a light, a BRIGHT one, on the solar radiation senor in order to get the system to "test" for codes beyond that one.
