Detection condition

• U0001:88

• Start stop unit detects the CAN bus communication line (HS-CAN) malfunction 10 times continuously with the ignition switched ON (engine off or on).

• U0100:00

• Start stop unit could not receive the CAN signal from the PCM for 1 s or more with the ignition switched ON (engine off or on).

• U0101:00

• Start stop unit could not receive the CAN signal from the TCM for 1 s or more with the ignition switched ON (engine off or on).

• U0121:00

• Start stop unit could not receive the CAN signal from the DSC HU/CM for 1 s or more with the ignition switched ON (engine off or on).

• U0121:87

• Start stop unit could not receive the CAN signal from the DSC HU/CM for 10 s or more with the ignition switched off.

• U0131:00

• Start stop unit could not receive the CAN signal from the electric power steering (EPS) control module for 1.2 s or more with the ignition switched ON (engine off or on).

• U0140:00

• Start stop unit could not receive the CAN signal from the BCM for 5 s or more with the ignition switched ON (engine off or on).

• U0146:00

• Start stop unit could not receive the CAN signal from the BCM for 5 s or more with the ignition switched ON (engine off or on).

• U0151:00

• Start stop unit could not receive the CAN signal from the SAS control module for 1 s or more with the ignition switched ON (engine off or on).

• U0155:00

• Start stop unit could not receive the CAN signal from the instrument cluster for 5 s or more with the ignition switched ON (engine off or on).

Possible cause

• Malfunction in CAN bus communication line

• Malfunction in CAN line between PCM and start stop unit

• Malfunction in CAN line between TCM and start stop unit

• Malfunction in CAN line between DSC HU/CM and start stop unit

• Malfunction in CAN line between electric power steering (EPS) control module and start stop unit

• Malfunction in CAN line between BCM and start stop unit

• Malfunction in CAN line between SAS control module and start stop unit

• Malfunction in CAN line between instrument cluster and start stop unit
