I'm more familiar with fords, but I'm wondering if it is possible to pull the codes from the engine's computer on these cars? If so, please advise.

thanks

The only OBD items on that car (88 700) would be the ignition (all), SRS(all with airbags), and Electronic climate control (if it is a 760 or 780).

Abe, I may have to stand corrected on this but i don't believce there are any stored codes on the 88. If there are i would love to know details. I have no connector on my 88 740.

I forgot one part: the test lead is attached to an LED for flash diplay or you may also use a voltmeter or even a dwell meter as a pulse counter. The other lead from meter or LED will go to 12V +. The ignition ECU provides grounds on this terminal to diplay codes but it is a low amp terminal with a limit of 25 mA +/- (regular test light will not light).

The ignition system on your car (all Bosch ignition 700's from 84-88 all and the 89 turbos) has a lead on the driver's side inner fender with a pink remote starter wire and another wire that is red/yellow on some and some other color I can't recall on the others. This wire can display single digit codes once you've driven car and do not switch off ignition, there is no storage of codes. The codes are few and basically tell you that there is no load signal from LH fuel inj via two flashes and there is no knock sensor input via 4 flashes.

If your car has the airbag then it has stored codes anytime the SRS lamp is lit after you start engine.

Check the 700/900 FAQ (in the OBD Codes section) under "Features" above for full instructions.
