The service information contained in this manual refers to the Federal calibration package. The export change is NOT reflected in the service information on the DTC's diagnostic support information page or in the Repair Instructions. Export vehicles may have differences in DTC types that will affect malfunction indicator lamp (MIL) operation.
Type A: The PCM illuminates the malfunction indicator lamp (MIL) on the first drive trip that the diagnostic runs and fails.Type B: The PCM illuminates the malfunction indicator lamp (MIL) on the second consecutive drive trip that the diagnostic runs and fails.
Type C: The PCM illuminates the service throttle soon lamp only when there is more than one DTC (Type C) stored.
Type C*: The PCM will not illuminate a service lamp but will store a Failure Record on the first drive trip that the diagnostic runs and fails.
If a system is malfunctioning and the associated DTC has been disabled (Type X), it may be beneficial to use the diagnostic table as a guide to aid in diagnosis. Many of the DTC tables include a functional check of the system that may pinpoint a problem. However, it is important to remember that the DTC tables are specifically designed for use only when a DTC is set. Therefore, a thorough understanding of the normal operation of the system being diagnosed is necessary. The use of the tables for this purpose is at the discretion of the technician.
Important: For Automatic Transmission DTC types, refer to Scan Tool Data Definitions in Automatic Transmission - 4L80-E.
