BCM Data Display
- Code ".7.0" must be displayed on FDC panel before diagnostics can begin display of BCM data series. To display BCM data, depress and release "Outside Temp" button on CCP. BCM data series begins as display switches from code ".7.0 " to code "F.8.0".
- To advance display, depress "HI" button on CCP. To return to a lower numbered parameter or jump directly from "F.8.0" to the end of the parameter list ("P.3.1"), depress "LO" button on CCP.
- When BCM data display is first initiated, parameter numbers "P.2.0-P.3.1" will be displayed for one second on FDC, followed by numerical value. The parameter value will be displayed for 9 seconds. Each parameter and value will be repeated until manually advanced to next parameter.
- When trouble shooting a malfunction, BCM data display can be used to compare vehicle with a vehicle that is functioning properly. A summary of parameters with ranges and display units is contained in the BCM DATA PARAMETERS table.
