CRUISE CONTROL: DYNAMIC RADAR CRUISE CONTROL SYSTEM: C1A22, C1A23: Object Recognition Camera Incorrect Axial Gap
C1A23 - Object Recognition Camera Initialization Incomplete
DESCRIPTION
w/ Lane-keeping Assist System
If the driving support ECU determines that the lane recognition camera sensor assembly axis is deviated, DTC C1A22 is stored. Also, if the lane recognition camera sensor assembly beam axis adjustment is not performed after installing the lane recognition camera sensor assembly, DTC C1A23 is stored.
INSPECTION PROCEDURE
NOTICE:
When the lane recognition camera sensor assembly is replaced with a new one, adjust the lane recognition camera sensor assembly Adjustments.
PROCEDURE
1. ADJUST LANE RECOGNITION CAMERA SENSOR ASSEMBLY
(a) Adjust the lane recognition camera sensor assembly Adjustments.
NEXT -- Continue to next step.
2. CHECK DTC OUTPUT
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Clear the DTCs Dynamic Radar Cruise Control System.
