  • U0100:00
    • Communication error with PCM
  • U0101:00
    • Communication error with TCM
  • U0155:00
    • Communication error with instrument cluster
  • U0156:00
    • Communication error with connectivity master unit (CMU)
  • U0214:00
    • Communication error with start stop unit
Detection condition
  • U0001:88
    • Power liftgate (PLG) control module detects a CAN bus communication line (HS-CAN) malfunction.
  • U0100:00
    • Power liftgate (PLG) control module cannot receive the CAN signal from the PCM for 5 s or more.
  • U0101:00
    • Power liftgate (PLG) control module cannot receive the CAN signal from the TCM for 5 s or more.
  • U0155:00
    • Power liftgate (PLG) control module cannot receive the CAN signal from the instrument cluster.
  • U0156:00
    • Power liftgate (PLG) control module cannot receive the CAN signal from the connectivity master unit (CMU).
  • U0214:00
    • Power liftgate (PLG) control module cannot receive the CAN signal from the start stop unit.
Fail-safe
  • U0001:88
    • Stops the hands-free liftgate operation.
  • U0100:00
    • Stops the hands-free liftgate operation.
  • U0101:00
    • Stops the hands-free liftgate operation.
  • U0155:00
    • Stops the hands-free liftgate operation.
  • U0156:00
    • Stops the hands-free liftgate operation.
  • U0214:00
    • Stops the hands-free liftgate operation.
Possible cause
  • Malfunction in CAN bus communication line
  • Malfunction in CAN line between PCM and power liftgate (PLG) control module
  • Malfunction in CAN line between TCM and power liftgate (PLG) control module
  • Malfunction in CAN line between instrument cluster and power liftgate (PLG) control module
  • Malfunction in CAN line between connectivity master unit (CMU) and power liftgate (PLG) control module
  • Malfunction in CAN line between start stop unit and power liftgate (PLG) control module
