Lexus ES: Software Incompatibility with Cruise Control Module Invalid/Incompatible Software Component (U030557)
DESCRIPTION
The millimeter wave radar sensor assembly receives vehicle information from the forward recognition camera via CAN communication.
If the vehicle information stored in the forward recognition camera differs from that stored in the millimeter wave radar sensor assembly, the millimeter wave radar sensor assembly stores this DTC.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
U030557 | Software Incompatibility with Cruise Control Module Invalid/Incompatible Software Component | When the engine switch is on (IG), the vehicle information stored in the millimeter wave radar sensor assembly differs from that received from the forward recognition camera | -

CAUTION / NOTICE / HINT
NOTICE:
-
When replacing the millimeter wave radar sensor assembly, always replace it with a new one. If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in the millimeter wave radar sensor assembly will not match the information from the vehicle and a DTC may be stored.
-
When the millimeter wave radar sensor assembly is replaced with a new one, adjustment of the millimeter wave radar sensor beam axis must be performed.
