DTC U0001:88/U0100:00/U0101:00/U0151:00/U0155:00/U0214:00 [POSITION MEMORY CONTROL MODULE]

id0902o7468800

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
