Vehicle Set Up

Perform the following vehicle set-up prior to running any New Generation Star tests:

- Ignition switch in RUN.
- Vehicle transmission range (TR) position in P (PARK).
- Driver seat not occupied.
- Parking brake must be applied.
- All passenger compartment, hood and luggage compartment doors closed.
- All switches in the nominal OFF position. Do not touch any handle, control or switch that may produce a module input unless instructed to do so by New Generation Star program.

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).
