Entering BCM Data Display

With ".7.0" displayed on FDC (to cause ".7.0" to be displayed on the FDC, see INTRODUCTION TO DIAGNOSTIC TESTING under DIAGNOSTIC TESTING), depress and release OUTSIDE TEMP button on ECCP. BCM data series begins as display switches from ".7.0" to "F.8.0".
To advance display, depress HI button on ECCP. To return to a lower numbered display or jump directly from "F.8.0" to the end of display list, "P.3.1", depress LO button on ECCP.
When trouble shooting a malfunction, BCM data display can be used to compare the vehicle with problems to a vehicle that is functioning properly. See BCM DATA PARAMETERS table for list of BCM data parameters.

When BCM data display is first initiated, FDC will display a parameter check (P.2.0 or P.3.1) for one second and then a number will be displayed for 9 seconds to indicate parameter value. The display will continue to repeat this sequence of events until another parameter is selected.
