DTC Code DTC Name
U0101 Lost Communication with TCM
U0122 Lost Communication With Vehicle Dynamics Control Module
U0124 Lost Communication with Lateral Acceleration Sensor Module
U0126 Lost Communication with Steering Angle Sensor Module
U0130 Lost Communication with VGRS
U0293 Lost Communication with Hybrid Vehicle Control System
U114C Lost Communication with Suspension Control Module 1

DESCRIPTION

The absorber control ECU receives signals from the skid control ECU assembly, steering sensor, acceleration sensor (yaw rate sensor), VGRS ECU (front steering control ECU)* and hybrid vehicle control ECU assembly via CAN communication.

When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system first.

CAUTION / NOTICE / HINT

Note


  • Before performing troubleshooting, inspect the connectors of related circuits.

  • If DTC C1782 (Power Source Voltage Malfunction) is output at the same time, perform troubleshooting for C1782 first.

PROCEDURE


  1. CHECK FOR DTCS


    1. Clear the DTCs.

      Click here


      Chassis > Adaptive Variable Suspension System > Clear DTCs

    2. Turn the power switch off.

    3. Drive the vehicle at a speed of 30 km/h (19 mph) or more for 10 seconds or more.

    4. Check for DTCs.
