ECM "SNAPSHOT?" Selection

Selection of "SNAPSHOT?" test type while in the ECM system level will allow the recall of up to 3 snapshots recorded at the time the ECM malfunction codes were set. See Figure . Also, one may trigger the recording of a snapshot upon demand. Pressing the "HI" button while in the ECM system level, will result in the display of "EXXX SNAPSHOT?". The "XXX" is the 3-digit diagnostic code that recorded the snapshot. While selecting snapshot, any of the following actions may be taken to control the display:

• Pressing "OFF" button on CCDIC panel will stop the test type selection process and return the display to the next available system selection.
• Pressing the "LO" button will allow scrolling through the list of ECM diagnostic codes that the ECM has stored a snapshot for. Pressing the "LO" button will display the "TAKE ECM SNAPSHOT?" message and return system to the first "EXXX SNAPSHOT?" display.
• Pressing the "HI" button with "SNAP DATA?" or "SNAP INPUTS?" displayed, will select that test type. At this point the display is controlled as it would be for non-snapshot data and input displays; however, all values and status information represents memorized vehicle conditions.
