厂商摘要

以下为英文原文

This Preliminary information communicates Vehicles may be setting DTC P2101 falsely. In 2017 the K2XX introduced a “Driver Door Open Prime” (DDOP) feature that improves cold startability. The engineering investigation has determined that an intermittent pulse on the ECM RUN/CRANK input (during vehicle door unlock), initializes the Electronic Throttle Control (ETC) diagnostics that falsely sets P2101 when the DDOP occurs as the customer opens the driver door. Many of the reported P2101 failures show that the vehicle battery was in a reduced charge state (new dealer stock or extended radio operation with the engine off).Run the engine for 1 minute, soak the vehicle for 5 hours (required to re-initialize the DDOP) and verify that the P2101 does not reset.Return the vehicle to the customer
