1. Not all codes shown apply to every vehicle model. 2. P Codes shown with a * symbol may cause a dashboard indicator lamp to light.
3. Many logged codes are transitory in nature and are automatically reset.
4. Codes shown below are for GM vehicles only.
5. DTC P1000 is an indication that the vehicle needs to be driven for a period so that the
vehicle can learn certain operating characteristics. This code cannot be cleared using
the DTC Reader clear function.
