Check Engine Light (CEL)

It would be nice to figure out a way to enable the check engine light. Most inspection stations in the USA require the check engine light on OBD1 cars (like the urS4 / urS6) to come on with key on for a few seconds, then go out. How can this be accomplished? Looking at the wiring diagrams the light appears to be ground-activated by the ECU on pin 22.
