Answer
Hi Claude,
Use the ignition switch to get a fault code from the computer:
"on-off-on-off-on and leave "on", doing that in an elapsed time of 5 seconds or less. Then watch the check engine light which remains "on" to begin to flash, pause, flash, etc. Count the number of flashes before each pause. Then repeat to be sure of an accurate count. Then group the numbers in pairs in the order of appearance to form the two digit fault code numbers. Then go to www.allpar.com/fix/codes.html for a translation or write back with the numbers and I'll go from there. The last number is always 55 because that means "end of readout". Also tell me which engine you have in the car.
