replacing the cluster isn't going to do you any well if you're not testing the bulb IN the cluster to make sure its not burnt out.. Also, irrc the ECU sends the signal to turn on the check-engine light, so you may want to make sure the ECU is pulling that PIN high (12v) or low (0v), dependent on how the bulb gets turned on from the ECU.

goodluck!

Thanks for the info - I now have a different cluster in there with a different bulb, so it shouldn't be a bulb issue.

I'm not sure what PIN means.
