Okay so do us a favor and you go and try and find out how he'd check the codes since the answer must be obvious in the FAQ topic, right?
*NEWSFLASH*
His car started out OBD0/Pre-OBD and thus used a blinking LED light to check codes when the key was turned into the on position.
The engine and ECU are now OBD1, which would require the use of a two prong jumper plug being jumped to then count blinking check engine lights in the guage cluster that serve as a sort of morse code with which you then see what problem codes you're throwing.
I don't know if the 88-91 chassis even has this two prong jumper since the ECU codes were intended to be read simpy, by turning the key to "on" and then reading the LED light directly on the ECU itself.

General consensus says to ground the D4 pin
However...this thread has a guy that says otherwise...and the OP chimed in that he could check the cel...

wrong
the D4(service check connector)(Brown wire) has to be joined/jumpered (only when troubleshooting codes, adjusting ignition timing, etc.) with the Green/White wire which is a "floating ground", common with the TPS, ECT, IAT and 02 sensors but not the chassis ground.

Gee...a little research goes a looooong way, doesnt it? Searched for a few mins, got exactly what you needed. Neat.

Well some codes will disable VTEC, especially if the codes themselves are being thrown because the VTEC doesn't work.
Some codes such as oxygen sensor, IAT, and fuel supply don't usually affect VTEC.
Other codes such as TDC, CYP, MAP, TPS, VSS, etc. will certainly disable VTEC and in the case of distributor related codes (TDC/CYP/CKP) the engine sometimes won't rev over 3500rpm or so.
