Information on Chassis Control Module (CCM) and Hybrid Powertrain Control Module (HPCM) Receives Invalid Data and Sets DTC U0422 The technician may find DTC U0422 set. The technician may also find the following DTCs set:
• U1534
• U1538 Based on analysis with the BCM and Hybrid Powertrain Control Module (HPCM) teams, during vehicle startup (on occasion) the PEPS module arbitration along with high bus traffic leads to the BCM or HPCM setting the door open switch virtual device availability (VDA) to unavailable. The BCM or HPCM does not update the VDA back to Available until the door switch changes state (this signal is event based as opposed to periodic). The ICCM and HPCM sets the U0422 DTC after 1 second of either the door ajar VDA or door open VDA being unavailable
