Retrieving Parameter Identification (PID) Information
NOTE:
This procedure may be used to verify operation of input circuitry for selected module being tested.
- 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 PID from a specified test procedure, ensure ignition is in proper position as listed 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 DIAGNOSTIC DATA LINK menu and press trigger.
- Rotate dial on NGS tester to highlight the desired module you wish to access and press trigger. Rotate dial on NGS tester to PID/DATA MONITOR AND RECORD and press trigger.
- Rotate dial on NGS tester to highlight the PID acronyms you wish to view and press trigger. Repeat this procedure until all desired PIDs are selected. When all PID acronyms have been selected, press button No. 7 to view all selected PIDs.
- For GEM and RAP PID identification and expected values, see appropriate PARAMETER IDENTIFICATION (PID) IDENTIFICATION table.
