DESCRIPTION
This DTC is stored when the blind spot monitor sensor RH detects a +B short in the blind spot monitor indicator RH.
DTC Code |
DTC Detection Condition |
Trouble Area |
---|---|---|
C1AB1 |
With the blind spot monitor main switch assembly (warning canceling switch assembly) on, the voltage applied to the indicator is high for a certain amount of time even though the blind spot monitor sensor is not outputting voltage to the indicator. |

Front Radar Sensor Incorrect Axial Gap (C1A11,C1A14)
DESCRIPTION
When the system determines that the vehicle is driving straight ahead based on
signals from the yaw rate and acceleration sensor (airbag sensor assembly), etc.,
the millimeter wave radar sensor assembly performs self-diagnosis to check if the
sensor beam axis is misaligned.
