According to the Bentley you can pull fault codes using a home made jumper wire and a switch.
"•As a general rule, a steady-on Check Engine light means the
LH control unit has detected a fault. A flashing Check Engine
light means that the EZK Ignition system has detected a fault.
As an exception to the rule, the check engine light on 1992
models does not flash. Therefore, a steady-on Check Engine
light on these models could be either an EZK system or an LH
system fault." (source is Bentley Manual pg. 151 Section 240-4) after this section it starts on how to use the switch and jumper wire, gives the test procedure and the fault codes.
