Code No.U1073: Bus off
CAUTION
• If diagnosis code U1073 is set in the
TCL/ASC-ECU, always diagnose the CAN
main bus line. If there is any fault in the CAN
bus lines, an incorrect diagnosis code may be
set.
• Whenever the ECU is replaced, ensure that
the communication circuit is normal.
TROUBLE JUDGMENT
This code is stored when the TCL/ASC-ECU has
ceased the CAN communication (bus off). Then, if a
penalty mode is entered after approximately five
minutes, regular data transmission will be cancelled.
PROBABLE CAUSES
• Damaged wiring harness or connector
• Malfunction of the hydraulic unit (integrated with
TCL/ASC-ECU)
