Second-row seat

DTC U0001:88/U0100:00/U0155:00/U0214:00 [REAR ONE-TOUCH WALK-IN CONTROL MODULE] DETECTION CONDITION AND POSSIBLE CAUSE

Description	U0001:88 Module communication error (HS-CAN) U0100:00 Communication error with PCM U0155:00 Communication error with instrument cluster U0214:00 Communication error with start stop unit
Detection condition	U0001:88 Rear one-touch walk-in control module detects the CAN bus communication line (HS-CAN) malfunction with the ignition switched ON (engine off or on). U0100:00 Rear one-touch walk-in 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). U0155:00 Rear one-touch walk-in 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 Rear one-touch walk-in 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 the rear one-touch walk-in operation function from being driven for the second-row seat (LH). Inhibits the rear one-touch walk-in operation function from being driven for the second-row seat (RH). U0100:00 Inhibits the rear one-touch walk-in operation function from being driven for the second-row seat (LH). Inhibits the rear one-touch walk-in operation function from being driven for the second-row seat (RH). U0155:00 Inhibits the rear one-touch walk-in operation function from being driven for the second-row seat (LH). Inhibits the rear one-touch walk-in operation function from being driven for the second-row seat (RH). U0214:00 Not applicable
Possible cause	Malfunction in CAN bus communication line Malfunction in CAN line between PCM and rear one-touch walk-in control module Malfunction in CAN line between instrument cluster and rear one-touch walk-in control module Malfunction in CAN line between start stop unit and rear one-touch walk-in control module
