Selecting Test Type Level
Selection of PCM DATA, PCM INPUTS, PCM OUTPUTS, PCM OVERRIDES, PCM CLEAR CODES or PCM SNAPSHOT test may be displayed. (Scheme 37) If dashes appear in DIC, test is not valid or test conditions are wrong. While selecting a specific test, any of following actions may be taken to control display
- Depressing HI (fan up) button on CCP will display a specific output or test parameter for selected test type level (i.e., PCM data parameter PD01, etc.). (Scheme 37)
- Depressing LO (fan down) button on CCP will display next test type level for system level (i.e., PCM INPUTS?, PCM OUTPUTS?, etc.). (Scheme 37) This allows display to be cycled through all available test type choices. This list of test types can be repeated following display of last test type.
- Depressing OFF button on CCP will stop test selection process and return display to next system level (i.e., IPC?).
