5. Perform the DATA LINK DIAGNOSTIC TEST. If the NGS responds with:
^ CKT9 14, CKT9 15 or CKT7O = ALL ECUS NO RESP/NOT EQUIP.
^ NO RESP/NOT EQUIP for RAP, go to Pinpoint Test D.
^ SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the RAP module.
6. If the DTCs retrieved are related to the concern, go to the RAP Module Diagnostic Trouble Code (DTC) Reference Chart to continue diagnostics.
