Retrieving Diagnostic Trouble Codes

NOTE: Procedure may be used for retrieving continuous Diagnostic Trouble Codes (DTCs).

Connect New Generation Star (NGS) tester to Data Link Connector (DLC) and perform proper hook-up procedure. See EQUIPMENT HOOK-UP .
NOTE: If instructed to retrieve Diagnostic Trouble Codes (DTCs) from a specified test procedure, ensure ignition is in proper position as indicated in test procedure or the test will fail.
Turn ignition switch to RUN position unless otherwise instructed by specified test procedure. Rotate dial on NGS tester to select DIAGNOSTIC DATA LINK menu and press trigger.
Rotate dial on NGS tester to highlight the desired module you wish to access. Ensure DIAGNOSTIC TEST MODE is highlighted and press trigger.
Rotate dial on NGS tester to highlight RETRIEVE/CLEAR CONTINUOUS DTC and press trigger. Press button No. 7 to initiate procedure.
Record all Diagnostic Trouble Codes (DTCs) that are displayed for specified module. Proceed to appropriate DTC IDENTIFICATION table for DTC identification and reference for proper DTC testing procedure.
If NGS tester display indicates SYSTEM PASSED (NO DTC'S AVAILABLE), press CANCEL and proceed to ON-DEMAND SELF-TEST.
