Selecting System Level

WARNING: This page is about a different car, the 1993 Cadillac Seville and 1993 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.

Following trouble code display, first available system will be displayed (i.e., IPC?). When selecting a system to test, any of following actions may be taken to control display:

  1. Depressing HI (fan up) button on CCP will select displayed system for testing (i.e., PCM DATA, PCM INPUTS, PCM OUTPUTS, etc.). See Figure .
  2. Depressing LO (fan down) button on CCP will display next available system selection (i.e., IPC?, ACP? or SIR?). This allows display to be cycled through all system choices. This list of systems can be repeated following end of system list.
  3. Depressing OFF button on CCP will stop system selection process and return display to beginning of PCM trouble code sequence.
