id0802g8824200

System malfunction location

•  U0001:88: Unit 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

•  The SAS control module detects a CAN communication line (HS-CAN) error.

U0100:00

•  The SAS control module could not receive CAN signal from the PCM for 5 s or more.

U0101:00

•  The SAS control module could not receive CAN signal from the TCM for 5 s or more.

U0155:00

•  The SAS control module could not receive CAN signal from the instrument cluster for 5 s or more.

Fail-safe function

Not applicable

Possible cause

•  Malfunction in CAN bus communication line

•  Malfunction in CAN line between the SAS control module and PCM

•  Malfunction in CAN line between the SAS control module and TCM

•  Malfunction in CAN line between the SAS control module and instrument cluster
