ACP Snapshot Test

WARNING: This page is about a different car, the 1995 Cadillac Seville, 1995 Cadillac Eldorado, and 1995 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
  1. Selecting snapshot test type while in ACP system level allows up to 3 snapshots, recorded at time of setting ACP trouble codes, to be recalled. A snapshot can also be recorded upon demand.
  2. Selecting snapshot (pressing blower fan up arrow (HI) button) while in ACP system results in display of X### SNAPSHOT (### is 3-digit trouble code). See Figure and Figure . When selecting snapshot test type, several options are available:
    • Press blower fan down arrow (LO) button to scroll through ACP trouble codes list for snapshots stored in memory. After last ACP code (or third, if more than 3 codes are set), pressing LO button results in display of TAKE SNAPSHOT? message. Pressing LO button again will return to first X### SNAPSHOT? display.
    • Pressing blower fan up arrow (HI) button at X### SNAPSHOT display changes display to X### DATA or SNAP DATA message to select snapshot data values. See ACP DATA DISPLAY CODES. Press HI button to select a data test or press LO button to go to X### INPUTS or SNAP INPUTS selection. Pressing HI button here selects input test. Pressing LO button here will display X### DATA or SNAP DATA screen again. At each data or input test, display is controlled as it would be for non -snapshot data and input displays; however, all values and status information represent memorized vehicle conditions.
    • Pressing HI button with TAKE SNAPSHOT displayed will display SNAPSHOT TAKEN message to indicate new information has been stored in memory. After a few seconds, display will change to X### DATA or SNAP DATA screen.
    • Pressing OFF with X### SNAPSHOT displayed will return display to next available test selection.
