It depends on the code. The Service Electronic Throttle System message, which is set by some 88 conditions, will stop all Regens. Any code that sets Limp Home Mode will stop Regens. And then there are other codes that do not effect Regens. It sounds like your code, which you did not name, may be one that stops Regens.
