Visual Inspection Chart:
2. Inspect to determine if any of the mechanical or electrical concerns from the Visual Inspection Chart apply.
3. If the inspection reveals an obvious concern that is readily serviced, correct the concern before continuing with Inspection and Verification.
4. If a concern remains after the inspection, use Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent connected to the data link connector (DLC) to retrieve continuous diagnostic trouble codes (DTCs) and to execute Self Test Diagnostics for the fuel indication module (FIM). If after performing data link diagnostic tests, the New Generation Star (NGS) Tester responds with fuel indication module, no responselnot equipped, GO to Pinpoint Test A. A: No Communication With Fuel Indication Module (FIM)
5. If self test is passed and no diagnostic trouble codes (DTCs) are retrieved, GO to the Symptom Chart to continue diagnostics. Symptom Related Diagnostic Procedures
6. If diagnostic trouble codes (DTCs) are retrieved, GO to the Fuel Indication Module (FIM) Diagnostic Trouble Code (DTC) Index. Natural Gas Vehicle
7. If the fuel indication module (FIM) cannot be accessed by the New Generation Star (NGS) Tester, GO to Pinpoint Test A. A: No Communication With Fuel Indication Module (FIM)
