Firebird BCM working! (Page 10/10) Cajun APR 30, 03:53 PM Tom, I'm sorry to say that I cannot locate my copy of the 2002 FSM! I have or had a digital copy. I do however have a hard copy of the section pertaining to the BCM. DTC 25/35 is for Security Indicator status DTC 23/33 is for RAP feed shorted to ground or battery DTC 55 is for Begin Configuration Display. Clearing BCM DTC codes: Current DTC's (21 -25) remain stored by the body control module (BCM) and are displayed in the diagnostic mode as long as the BCM detects the fault. Once the fault is corrected, the current DTC's are cleared by the BCM. To clear history DTC's (31 - 35) press and hold the door unlock switch for four seconds while the BCM is in the diagnostic mode. The BCM will sound three audible warning tones to confirm the DTCs are cleared. Lunatic OCT 09, 01:18 PM I know this thread is aimed at installing the 98-02 F-body BCM into the Fiero. However, I've successfully installed a 2003 Cavalier BCM into my Fiero. I've swapped in the L61 Ecotec and matching 22682857 BCM into my car and it works. The only circuit that I was interested in was the interior lighting control though. This circuit works as intended and I just wanted to let others know. rbell2915 JUL 11, 09:49 PM I went to the yard the weekend before last and grabbed one of these BCMs. I am looking forward to getting this installed in the Formula I'll be picking up in the near future.
