• U0100:00

• Start stop unit could not receive the CAN signal from the PCM for 1 s or more.

• U0101:00

• Start stop unit could not receive the CAN signal from the TCM for 1 s or more.

• U0121:00

• Start stop unit could not receive the CAN signal from the DSC HU/CM for 1 s or more.

• U0121:87

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

• U0131:00

• Start stop unit could not receive the CAN signal from the EPS control module for 1.2 s or more.

• U0140:00

• Start stop unit could not receive the CAN signal from the front body control module (FBCM) for 5 s or more.

• U0146:00

• Start stop unit cannot receive the CAN signals from the instrument cluster for 5 s or more.

• U0151:00

• Start stop unit could not receive the CAN signal from the SAS control module for 1 s or more.

• U0155:00

• Start stop unit could not receive the CAN signal from the instrument cluster for 5 s or more.
