New Generation Star Tester Driven Diagnosis

Vehicle Set Up

Perform the following vehicle set-up prior to running any New Generation Star tests:
- Ignition switch in RUN
- Vehicle PRNDL position in P (PARK)
- Driver's seat not occupied
- Parking brake must be applied
- All passenger compartment, engine compartment 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. New Generation Star Tester Hookup and Vehicle Selection
2. Retrieve continuous DTC's from selected module. Retrieve/Clear Continuous DTCS
3. Record all continuous DTC's, then clear all DTC's from the selected module. Retrieve/Clear Continuous DTCS
4. Perform Data Link Diagnostics Test to check the Multiplex Communication Network. Multiplex Communication Network Data Link Diagnostics Test

If the MCN Data Link Diagnostics Test passed and concern(s) still remains, then go to Step 5.

5. NOTE: The Self-Test program for an individual module may produce observable outputs. For example, the self-test for Lighting Control Module will flash certain lamps and the self-test for the Driver's Seat Module will cause the seat to travel through a limited range of motion.

Perform On-Demand Self-Test on the selected module. On-Demand Self-Test

6. Record all On-Demand Self-Test DTC's and go to Diagnostic Trouble Codes to continue diagnosis.

If On-Demand Self-Test passed and concern(s) still remains, then go to Step 7.

7. Use the continuous DTC's recorded in Step 3 and go to Diagnostic Trouble Codes to continue diagnosis.

If no continuous DTC's retrieved in Step 3, then concern(s) is not related to Multiplex Communication Network. Return to referred section for non-network related problem(s).
