What does it mean when it says no powertrain Dtcs or freeze frame data?
The data you want to retrieve has to be stored in the computer so you have to induce a code set. Currently there are no codes stored.
What is Freeze Frame in diagnostics?
It’s a snapshot of sensor or component readings (parameter values) captured at the moment when the electronic control unit detected a malfunction. In addition, the freeze frame contains the Diagnostic Trouble Code (DTC) that the computer system identified as the reason for the malfunction.
What causes a camshaft to fail a DTC Test?
The test fails when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position. Possible Causes: Camshaft timing improperly set Continuous oil flow to the VCT piston chamber VCT solenoid valve stuck open Camshaft advance mechanism binding (VCT unit) Diagnostic Aids: This DTC is a functional check of the VCT unit.
What happens if you delete a DTC on a computer?
These are all actions that cannot be ignored. An example would be if a DTC says a calibration is needed. If the DTC is just deleted, the system may not reset the DTC until a certain distance is travelled. This means the system may not be functioning correctly.
What causes an engine to have a DTC?
Possible Causes: Camshaft timing improperly set Continuous oil flow to the VCT piston chamber VCT solenoid valve stuck open Camshaft advance mechanism binding (VCT unit) Diagnostic Aids: This DTC is a functional check of the VCT unit. Diagnose any base engine concerns related to the engine oil pressure or engine timing.
Do you hook up scan tool and clear DTCs?
There is a misconception in the collision repair industry that when the physical repairs are completed, you hook up a scan tool, and clear all codes. This should not be the typical process. In order to properly repair the vehicle, the DTCs need to be recorded, investigated, and a decision made on how they should be handled.
