The electronic brake control module (EBCM) Scan Tool Data Lists contain all the antilock brake system related parameters that are available on the scan tool. The parameters in the list are arranged in alphabetical order. The column, "Data List," indicates the location of the parameter within the scan tool menu selections.
Use the EBCM Scan Tool Data Lists as directed by a diagnostic table or in order to supplement the diagnostic procedures. Begin all the diagnostic procedures with the antilock brake system (ABS) Diagnostic Starting Point. Use the EBCM Scan Tool Data Lists only after the following is determined:
| • | There is no published DTC procedure nor published symptom procedure for the customer concern. |
| OR |
| • | The DTC or symptom diagnostic procedure indicated by the diagnostic system check does not resolve the customer concern. |
The Typical Data Values are obtained from a properly operating vehicle under the conditions specified in the first row of the Scan Tool Data List table. Comparison of the parameter values from the suspect vehicle with the Typical Data Values may reveal the source of the customer concern.
The ID Information menu is located on the EBCM main screen.
