DTC U0001-88; U0100-00; U0101-00; U0151-00; U0155-00; U0214-00; Module Communication Errors: Notes

DETECTION CONDITION AND POSSIBLE CAUSES

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 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
