Your car [ 140.057 ] has analog - flash code system that is easily DIYer accessed..

There are 60 codes that will bring on a CE lamp code and the fault/s that have tripped yours are stored in the Diagnostic Module .
On Ca. vehicles , there is a sw/led to access, on Fed , you make a simple led tool [ archives] ..

The codes and pin # on the DM connector to access these is here [ on page 37]
Also read the intro on code access....

Don't do anything until you get the codes .. the DM is the brain that put the CE lamp ON and it is the brain that will tell you why it did so...
