4. If the concern remains after the inspection, connect the New Generation Star (NGS) Tester 41 8-F048 (007-00500) or equivalent scan tool to the data link connector (DLC) located beneath the instrument panel to perform DATA LINK DIAGNOSTICS test.

If the DATA LINK DIAGNOSTICS test is passed for the module retrieve continuous DTCs and execute self test diagnostic for the module to retrieve current DTCs.
5. If DTCs are retrieved, go to the Module Diagnostic Trouble Code (DTC) Index to continue diagnostics.
6. If self test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics.Symptom Chart
