OBD PRODUCTION VEHICLE EVALUATION (PVE) TESTING
PVE testing is required to confirm production vehicles meet government regulations. There are three parts involved in PVE testing and WinterPark has the experience to help our clients satisfy all aspects of the requirements below.
An important aspect of the CARB OBD regulation is the vehicle testing requirements. Manufacturers are required to perform Production Vehicle Evaluation (PVE) testing. PVE testing has three separate requirements: PVE1 (Verification of Standardized Requirements), PVE2 (Verification of Monitoring Requirements), and PVE3 (Verification and Reporting of In-use Monitoring Performance).
WinterPark Engineering has extensive experience supporting manufacturers with all types of PVE testing. WinterPark’s Generic Scan Tool Communication testing (PVE1) is ideal for end of line testing. Incorporating automated OBD testing at the end of the production line can help manufacturers catch legislative diagnostic issues before they leave the production facility, saving significant time and money.
PARTS INVOLVED IN PVE TESTING
PVE1
Scan Tool Communication Verification (SAE J1979 / J1939)
Within 2 months of the start of production, manufacturers are required to ensure their vehicle properly communicates emission related messages to a generic scan tool.
PVE2
Test each diagnostic on the vehicle by simulating hardware faults
Within 9 months after the start of production, manufacturers are required to perform a full evaluation of the OBDII system. This involves demonstrating each diagnostic is able to detect a fault, illuminate the MIL, and store a confirmed and permanent fault code. Healing of the fault and erasing permanent fault codes is also required. A full test plan requires approval by CARB prior to starting this testing.
PVE3
OBD In-Use Monitoring Performance Ratio (IUMPR) Data Collection
Within 12 months after the start of production, manufacturers are required to collect in-use monitoring data from vehicles which are contained in test groups. A minimum of 15 vehicles from each group is required.
