Input Displays: Notes

Input displays are operated as defined under SELECTING THE TEST TYPE  . When troubleshooting a malfunction, the PCM, BCM, LIGHTING, or RTD input display can be used to determine if the switched inputs can be properly interpreted. When one of the various input tests is selected, the state of that device is displayed as HI or LO. The display also indicates if the input changed state so that the technician can activate or deactivate any listed device and return to the display to see if it changed state. If a change of state occurred, an "X" will appear next to the HI/LO indicator, otherwise a "O" will remain displayed. The "X" will only appear once per selected input although the HI/LO indication will continue to change as the input changes. Some tests are momentary and the "X" can be used as an indication of a change. The following is a list of PCM, BCM and LIGHTING inputs.
