retrieving engine diagnostic codes on a 1988 model comanche

[kyjeep40330]

Can this be done or was this model too early? I had a '91 jeep that I could simply turn the ignition key to acc. three times and the check engine light would flicker the codes. Probably a stupid question but I appreciate your help.

'90 and older, actually.

 

The newer Chrysler system didn't come on-line until the 1991 model year. 1990 was still Renix.
