Displaying CCM Input Status

Display of CCM input status is used to determine if CCM is monitoring proper system operation.For example, courtesy light operation requires seeing a door open, indicated by the door ajar switch. If the courtesy lamps are not operating properly, a starting point may be selecting this diagnostic function and watching if the CCM recognizes the door opening and closing.

To enter display CCM input status function, press TRIP/ODO (next test) button on DIC until "1.3" displays on trip monitor. Press ENG/MET (next value) button until identifying number for input status is displayed in the first 2 digits of odometer. See CCM INPUT IDENTIFICATION NUMBER table. Press INST/AVER (previous value) button to go backward in the list.
Input status is displayed in the last 3 digits of odometer. Input status will display as "1" (on) or "0" (off). Display will constantly move to the left one digit at a time. First 2 digits in odometer indicate last 2 states of selected input. Third digit indicates current state of input. For example, "101" when in door ajar status indicates door was open(on), closed (off), then opened again (on).
If input status does not change during testing, a "1" indicates a possible short or faulty switch, and a "0" indicates a possible open or faulty switch. Exceptions to this are input status 01, 02, 06 and 14, which should not change and cannot be changed during diagnostics.
