Secondaries Question

[Funmart6]

If you tie the secondaries open and unplug the IMRC box, should the computer still throw out a code?

It will for several cycles then it will clear.

Mine never did, but I did it to a friend's SHO and it did.

Could you define what exactly you mean by "cycle", and thanks for the answers to my questions.

When the tranny guys put the engine cover back on I guess they saw the box was unplugged and plugged it back up, so I unplugged it again and I am getting a SES light, haven't checked for the code but the tranny guy said it was giving him an "IMRC" code and he didn't know what that was, I explained how the IMRC worked and why it would give a code, got the car home, took the cover off and sure enough--the box was plugged up, so I unplugged it. The butterflies were still tied open though. So it should stop lighting up the SES after a while then right?

Driving cycles. Meaning you start and drive car. The PCM will run its normal diag and after several cycles it will quit setting a SES light for the IRCM.
