DESCRIPTION

DTC No. Detection Item DTC Detection Condition Trouble Area Note
U110F Lost Communication With Roll Rate Sensor/Vertical Acceleration Sensor Module No communication from the roll rate and vertical acceleration sensor continues.

  • Open or short in V3 bus main line or connector

  • Short in V3 bus branch line or connector

  • Open in roll rate and vertical acceleration sensor branch line or connector

  • Skid control ECU (brake actuator assembly)

  • ECM

  • Torque vectoring differential ECU assembly

    (w/ Torque Vectoring Differential System)

  • Roll rate and vertical acceleration sensor

  • Open or short in No. 10 CAN junction connector (for LHD)

  • Open or short in No. 6 CAN junction connector (for RHD)

  • Open or short in No. 8 CAN junction connector
Tip:

As there is no sub bus monitor ECU for V3 bus, each ECU detects communication stops and stores DTCs.
U1172 Lost Communication with Vehicle Dynamics Control Module (ch2) No communication from the skid control ECU (brake actuator assembly) continues.

  • Open or short in V3 bus main line or connector

  • Short in V3 bus branch line or connector

  • Open in torque vectoring differential ECU assembly branch line or connector

  • Skid control ECU (brake actuator assembly)

  • ECM

  • Torque vectoring differential ECU assembly

  • Roll rate and vertical acceleration sensor

  • Open or short in No. 10 CAN junction connector (for LHD)

  • Open or short in No. 6 CAN junction connector (for RHD)

  • Open or short in No. 8 CAN junction connector
Tip:

As there is no sub bus monitor ECU for V3 bus, each ECU detects communication stops and stores DTCs.
Tip:

This diagnostic procedure is for when the torque vectoring differential ECU assembly (TVD) outputs only DTC U1172, the skid control ECU (brake actuator assembly) (ABS/VSC/TRAC) outputs only DTC U110F, or DTC U1172 and U110F are output simultaneously.

CAUTION / NOTICE / HINT

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.

Note:

  • Because the order of diagnosis is important to allow correct diagnosis, make sure to begin troubleshooting using How to Proceed with Troubleshooting when CAN communication system related DTCs are output.

  • Before measuring the resistance of the CAN bus, turn the engine switch off and leave the vehicle for 1 minute or more without operating the key or any switches, or opening or closing the doors. After that, disconnect the cable from the negative (-) battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.

  • After turning the engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.

    Click here

  • After performing repairs, perform the DTC check procedure and confirm that the DTCs are not output again.

    DTC check procedure: Turn the engine switch on (IG) and wait for 1 minute or more. Then operate the suspected malfunctioning system and drive the vehicle at 60 km/h (37 mph) or more for 5 minutes or more.

  • After the repair, perform the CAN bus check and check that all the ECUs and sensors connected to the CAN communication system are displayed as normal.

Tip:

  • Before disconnecting related connectors for inspection, push in on each connector body to check that the connector is not loose or disconnected.

  • When a connector is disconnected, check that the terminals and connector body are not cracked, deformed or corroded.
