DTC U0001:88/U0100:00/U0101:00/U0155:00 [RETRACTABLE HARDTOP CONTROL MODULE]

id0902r4077900

Description	•  U0001:88 ―  Module communication error (HS-CAN) •  U0100:00 ―  Communication error with PCM •  U0101:00 ―  Communication error with TCM •  U0155:00 ―  Communication error with instrument cluster
Detection condition	•  U0001:88 ―  Retractable hardtop control module detects the CAN bus communication line (HS-CAN) malfunction 10 times continuously with the ignition switched ON (engine off or on). •  U0100:00 ―  Retractable hardtop 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 ―  Retractable hardtop control module could not receive the CAN signal from the TCM for 1 s or more with the ignition switched ON (engine off or on). •  U0155:00 ―  Retractable hardtop control module could not receive the CAN signal from the instrument cluster for 2 s or more with the ignition switched ON (engine off or on).
Fail-safe	•  U0001:88 ―  Stops retractable hardtop operation •  U0100:00 ―  Stops retractable hardtop operation •  U0101:00 ―  Stops retractable hardtop operation •  U0155:00 ―  Stops retractable hardtop operation
Possible cause	•  Malfunction in CAN bus communication line •  Malfunction in CAN line between PCM and retractable hardtop control module •  Malfunction in CAN line between TCM and retractable hardtop control module •  Malfunction in CAN line between instrument cluster and retractable hardtop control module
