Pinpoint Test QE: Electronic Throttle Control (Etc) System

  1. Normal Operation and Fault Conditions 

    Refer to the DTC Fault Trigger Conditions.

    The informational Diagnostic Trouble Codes (DTCs) are the result of the failure mode effects management operating strategy that maintains limited vehicle function in the event of a PCM, harness or component concern.

    Circuit Diagnostic Trouble Codes (DTCs) can be accompanied by the informational Diagnostic Trouble Codes (DTCs) and should be diagnosed first. Informational Diagnostic Trouble Codes (DTCs) without circuit Diagnostic Trouble Codes (DTCs) may or may not indicate the actual concern and should be diagnosed as a symptom.

    DTC Fault Trigger Conditions
