DTC U0100:00/U0101:00/U0151:00/U0155:00/U0214:00 (POSITION MEMORY SYSTEM) DETECTION CONDITION AND POSSIBLE CAUSES

Description 
  • 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 
  • U0100:00
    • Position memory control module could not receive the CAN signal from the PCM for 5 s or more  .
  • U0101:00
    • Position memory control module could not receive the CAN signal from the TCM for 5 s or more  .
  • U0151:00
    • Position memory control module could not receive the CAN signal from the SAS control module for 5 s or more  .
  • U0155:00
    • Position memory control module could not receive the CAN signal from the instrument cluster for 5 s or more  .
  • U0214:00
    • Position memory control module could not receive the CAN signal from the start stop unit for 5 s or more  .
Fail-safe function 
  • 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 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
