This information refers to Domestic and Export calibration packages. Use the DTCs that only apply to your specific RPO (Regular Production Option). Each DTC is directly related to a diagnostic test. The DTC sets based upon the DTC's individual running and setting criteria.
The following are the types of DTCs and their code characteristics:
• | Emissions related |
• | Requests illumination of the MIL on the first trip with a fail |
• | Stores a History DTC on the first trip with a fail |
• | Stores a Freeze Frame on the first trip with a fail |
• | Stores a Failure Record |
• | Updates the Failure Record the first time the test fails each ignition cycle |
• | Emissions related |
• | The code is enabled after the first trip with a fail |
• | The code is disabled if the second consecutive trip passes |
• | Requests illumination of the MIL on the second consecutive trip with a fail |
• | Stores a History DTC on the second consecutive trip with a fail |
• | Stores a Freeze Frame on the second consecutive trip with a fail |
• | Stores a Failure Record when the first test fails |
• | Updates the Failure Record the first time the test fails each ignition cycle |
• | Non-emissions related |
• | Requests illumination of the Service Lamp (not the MIL), or the service message on the first trip with a fail |
• | Stores a History DTC on the first trip with a fail |
• | Does not store a Freeze Frame |
• | Stores a Failure Record when the test fails |
• | Updates the Failure Record the first time the test fails each ignition cycle |
• | Non-emissions related |
• | Does not request illumination of any lamps |
• | Stores a History DTC on the first trip with a fail |
• | Does not store a Freeze Frame |
• | Stores a Failure Record when the test fails |
• | Updates the Failure Record the first time the test fails each ignition cycle |
• | Diagnostics that are coded in the software, but will not run for non-OBD II export vehicles |
• | Some domestic vehicles use DTCs |
• | Even though codes are not stored, the DTC Type Table can still be used as a resource when diagnosing problems with systems that are associated with the type X DTCs |
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 and use of the tables for this purpose is at the discretion of the technician.
