Caution / Notice / Hint

NOTE:

Because this DTC is related to a temporary loss of steering angle sensor zero point calibration, before proceeding with the inspection, it is useful to confirm whether the power source voltage was interrupted by an operation such as removal or disconnection of the battery.

HINT:

When DTC U0073, U0124 and/or U0126 is output together with DTC C1439 and/or C1445, inspect and repair the trouble areas indicated by DTC U0073, U0124 and/or U0126 first.
Refer to DTC U0073: Control Module Communication Bus OFF; DTC U0100: Lost Communication with ECM / PCM; DTC U0124: Lost Communication with Lateral Acceleration Sensor Module; DTC U0126: Lost Communication with Steering Angle Sensor Module; DTC U0128: Lost Communication With EPB Module; DTC U0130: Lost Communication with Steering Effort Control Module; DTC U0134: Lost Communication with DRS Module; DTC U0151: Lost Communication With Restraints Control Module [12/2017 - 09/2018]
When the speed sensor or the acceleration sensor (yaw rate sensor) has trouble, DTCs for the steering sensor may be output even when the steering sensor is normal. When DTCs for the speed sensor or acceleration sensor (yaw rate sensor) are output together with other DTCs for the steering sensor, inspect and repair the speed sensor and acceleration sensor (yaw rate sensor) first, and then inspect and repair the steering sensor.
