Volvo Repair: Volvo 1995 960 Check Engine Light, flash flash flash, example 121

Question
I recently bought this car (my second car of this type) from a Volvo dealer.  It has 101,150 miles on it and was well serviced by the dealer-car looks almost as new and runs very well.  Last night, 1 minute after starting the car to drive home from work, the "Check Engine" light came on.  All fluids are fresh and at the right level.  I have been using regular gas in both my '95 960s without problems (don't know if that would be a problem-book says to use premium gas).  Any ideas, Regis?  Thanks in advance, Paul

Answer
you would have to check for code sin the engine control unit below is how to do so.


in the engine bay on the drivers side near the strut tower there is a small black box with a wire attached to it.place the wire in the terminal marked 2.turn ignition key on (not started)press the small button for 1 second and the code will be displayed as a series of flashes.a red led displays the codes.the code will be three digits.small pause in between flashes for a single number long pause between flashes for the next number.example 121 will be flash.....flash..flash.....flash.repeat three times or until first code repeats itself.to erase the code after all codes have been checked hold the button for a good 5 seconds then release the light should light steady,then press for another 5seconds.this will erase the codes.  email me the codes and i will tell you what they are..socket 2is the fuel system 6 is ignition.
