Use the typical scan tool data values for comparison after you have completed the following steps:
| • | Performed the BCM diagnostic system check |
| • | Verified that the on-board diagnostics function correctly without displaying any DTCs |
The typical scan tool data values are an average of displayed values that are recorded from normally operating vehicles. The typical scan tool data values are intended to represent what a normally functioning system would display. The values you get may vary due to a low battery charge or other reasons. The values should be very close.
Use only the parameters that the tables list for diagnosis. If a scan tool reads another parameter, do not use the values in diagnosis. For more details on the scan tool typical data values and on the use of the scan tool for the diagnosis of BCM inputs, refer to the applicable diagnosis table. If all of the values are within the range that the table illustrates, refer to Diagnostic Aids in the applicable diagnostic trouble code table and the Symptom Subsection References Table.
