Subject: Re: SYS Code 1996 LT4 Coupe by bogus on 2008/12/27 15:43:13 Don't even bother replacing the cluster. The SYS code is from the CCM. The CCM - Central Control Module - is in the dash, below and behind the radio. It's really a pain to reach. The CCM controls and manages a number of things: 1. All IP functions 2. Integration with audio system (the SVC feature) 3. Integration with climate control programmer 4. Communications between ABS/ASR computer with PCM 5. Diagnostics for any number of ancillaries (horn and other things) 6. Airbag controller The FSM outlines a detailed testing procedure for the CCM. I do have a guide for the 1992/93, but the codes are different in 1996 (I am about 98% sure of this) and the pins in the ALDL that are jumped are different. I do not currently have access to my 1996 FSM, but I am sure someone does to give you direction. I agree that the battery is the #1 cause of this, but, if you just installed an aftermarket stereo, I would get suspicious. |
