DTC U0001-88/U0100-00/U0101-00/U0151-00/U0155-00/U0214-00: Communication Error (Position Memory Control Module): Notes

DTC U0001:88/U0100:00/U0101:00/U0151:00/U0155:00/U0214:00 (POSITION MEMORY CONTROL MODULE) DETECTION CONDITION AND POSSIBLE CAUSE

Description
  • U0001:88
    • Module communication error (HS-CAN)
  • U0100:00
    • Communication error with PCM
  • U0101:00
    • Communication error with TCM
  • U0151:00
    • Communication error with SAS control module
  • U0155:00
    • Communication error with instrument cluster
  • U0214:00
    • Communication error with start stop unit
Detection condition
  • U0001:88
    • Position memory control module the CAN bus communication line (HS-CAN) malfunction
  • U0100:00
    • Position memory control module could not receive the CAN signal from the PCM for 5 s or more with the ignition switched ON (engine off or on).
  • U0101:00
    • Position memory control module could not receive the CAN signal from the TCM for 5 s or more with the ignition switched ON (engine off or on).
  • U0151:00
    • Position memory control module could not receive the CAN signal from the SAS control module for 5 s or more with the ignition switched ON (engine off or on).
  • U0155:00
    • Position memory control module could not receive the CAN signal from the instrument cluster for 5 s or more with the ignition switched ON (engine off or on).
  • U0214:00
    • Position memory control module could not receive the CAN signal from the start stop unit for 5 s or more with the ignition switched ON (engine off or on).
Fail-safe
  • U0001:88
    • Memory seat positioning using position memory switch and remote transmitter:
      • If the ignition is switched ON (engine off or on), inhibits all memory seat positioning.
      • U0100:00
    • Memory seat positioning using position memory switch and remote transmitter:
      • If the ignition is switched ON (engine off or on), inhibits all memory seat positioning.
      • U0101:00
    • Memory seat positioning using position memory switch and remote transmitter:
      • If the ignition is switched ON (engine off or on), inhibits all memory seat positioning.
      • U0151:00
    • Memory seat positioning using position memory switch and remote transmitter:
      • If the ignition is switched ON (engine off or on), inhibits all memory seat positioning.
      • U0155:00
    • Memory seat positioning using position memory switch and remote transmitter:
      • Inhibits all memory seat positioning.
      • U0214:00
    • Memory seat positioning using remote transmitter:
      • Inhibits all memory seat positioning.
    • Memory registration using remote transmitter:
      • Inhibits the memory registration.
Possible cause
  • Malfunction in CAN bus communication line
  • Malfunction in CAN line between PCM and position memory control module
  • Malfunction in CAN line between TCM and position memory control module
  • Malfunction in CAN line between SAS control module and position memory control module
  • Malfunction in CAN line between instrument cluster and position memory control module
  • Malfunction in CAN line between start stop unit and position memory control module
