90 vette derm
 

I was wondering if anyone out there could help me locate a DERM (diagnostic energy reserve module) for my '90 coupe?I have made numerous contacts with no results. It seems GM no longer makes new ones.This module is needed to clear the inflatable restraint light as well as the seat belt warning.

let me apologize for my lack of technical terminology but if you are talking about this black plastic box with a button that attaches to the computer under the dash on the drivers side, to reset error codes, I have one. I bought it from one of those mags like Ecklers or Mid America - about 5 yrs ago. You have to press the button in a particular series to reset the error light. In my case it was an airbag light. I hear its a common problem in 90's (as mine is). It kept coming back on though. In my case, the sensor was bad and needed to be replaced. I dunno if this helps but i hope so.
