1. Hookup New Generation Star Tester and perform vehicle selection.
2. Perform Data Link Diagnostics Test to check the Multiplex Communication Network. If the MCN Data Link Diagnostics Test passed and
concern(s) still remains, then go to Step 3, if data link diagnostic test did not pass go to Multiplex Communication Network DTC Index or
Diagnostic Communication Network DTC Index.
3. Retrieve continuous DTCs from selected module.
4. Record all continuous DTCs, then clear all DTCs from the selected module.
NOTE: The Self-Test program for an individual module may produce observable outputs.
5. Perform On-Demand Self-Test on the selected module.
6. Record all On-Demand Self-Test DTCs and go to MODULE DTC INDEX Table to continue diagnosis. If On-Demand Self-Test passed and
concern(s) still remains, then go to Step 7.
7. Use the continuous DTCs recorded in Step 4 and go to MODULE DTC INDEX Table to continue diagnosis. If no continuous DTCs retrieved in
Step 4, then concern(s) is not related to Multiplex Communication Network. Return to referred component system for non-network related
problem(s).
Wiggle Test
The wiggle test is designed to help identify and locate intermittent failures in the vehicle wiring harness and system components. Upon entering wiggle
test, several inputs and outputs of the module are monitored for change of state. When a state change is encountered, an audible tone can be heard and/or
a diagnostic trouble code (DTC) will be displayed on the New Generation Star (NGS) tester 007-00500. For modules which store DTCs, the DTC
description will determine an open circuit, short to ground or a short to B+. By initiating wiggle test and pulling on different areas of the vehicle harness,
intermittent open and short circuits can be located and serviced.
1. Perform New Generation Star Tester Hookup and Vehicle Selection.
NOTE: The ignition switch must be in RUN position or test will fail.
