Tried pulling the codes on my neighbors 'new' 1992 DeVille, and I expected them to display in the digital instrument cluster. Nope! My '87 has a Fuel Data center that displays the codes. The '92 system went into diagnostic mode but nothing showed up in the instrument cluster. ?? I'm prolly doing something wrong, but no clue what? Help....
Thanks
Dave

Ecc is on right side of steering wheel, so look at that first to press and hold off and warmer. Then quickly look at the fuel data center read out of the left side of the steering wheel for code readout
