Dodge Journey: Vehicle emission control information label, trip definition
VEHICLE EMISSION CONTROL INFORMATION LABEL
All vehicles have a Vehicle Emission Control Information (VECI) Label. Chrysler permanently attaches the label in the engine compartment. It cannot be removed without defacing information and destroying the label.
The label contains the vehicle's emission specifications and vacuum hose routings. All hoses must be connected and routed according to the label.
TRIP DEFINITION
A "Trip" means vehicle operation (following an engine-off period) of duration and driving mode such that all components and systems are monitored at least once by the diagnostic system. The monitors must successfully pass before the PCM can verify that a previously malfunctioning component is meeting the normal operating conditions of that component. For misfire or fuel system malfunction, the MIL may be extinguished if the fault does not recur when monitored during three subsequent sequential driving cycles in which conditions are similar to those under which the malfunction was first determined.
Anytime the MIL is illuminated, a DTC is stored. The DTC can self erase only after the MIL has been extinguished. Once the MIL is extinguished, the PCM must pass the diagnostic test for the most recent DTC for 40 warm-up cycles (80 warm-up cycles for the Fuel System Monitor and the Misfire Monitor). A warm-up cycle can best be described by the following:
- The engine must be running
- A rise of 40º F (4.5º C) in engine temperature must occur from the time when the engine was started
- Engine coolant temperature must crossover 160º F (71º C)
- A "driving cycle" that consists of engine start up and engine shut off.
Once the above conditions occur, the PCM is considered to have passed a warm-up cycle. Due to the conditions required to extinguish the MIL and erase the DTC, it is most important that after a repair has been made, all DTC's be erased and the repair verified by running 1 good trip.
