Pinpoint Test N: DTC U0300:55

Normal Operation

The adaptive cruise control system is enabled when the vehicle speed is set and the Cruise-Control Module (C-CM), which is a radar sensor unit, determines the distance and relative speed of the vehicle that is in the path of travel. The C-CM can be aligned both vertically and horizontally. The vertical alignment is a manual procedure carried out by adjusting the C-CM adjustment screw. The horizontal alignment is a software procedure that is carried out internal to the C-CM. The C-CM communicates over the High Speed Controller Area Network (HS-CAN).

- DTC U0300:55 (Internal Control Module Software Incompatibility: Not Configured) - set by the C-CM as a continuous memory and on-demand DTC if the C-CM detects a misalignment of a new module. The radar needs to be aligned due to the alignment angle being out of range.

This pinpoint test is intended to diagnose the following:

- C-CM out of alignment



PINPOINT TEST N: DTC U0300:55

-------------------------------------------------
N1 INSPECT THE C-CM BRACKET


- Inspect for damage to the C-CM bracket.
- Is the C-CM bracket damaged?

Yes
REPAIR or REPLACE the C-CM bracket as necessary. REFER to Cruise-Control Module (C-CM) Service and Repair. TEST the system for normal operation.

No
GO to N2.

-------------------------------------------------
N2 CARRY OUT THE VERTICAL AND HORIZONTAL ALIGNMENT


- NOTE: The front bumper cover must be removed in order to carry-out the vertical alignment procedure.
- Carry out the alignment procedures for the C-CM. Refer to Cruise Control Module (C-CM) (with Sensor) Adjustment Adjustments.
- Does the C-CM align correctly?

Yes
The system is operating correctly at this time. The concern was caused by a misaligned sensor.

No
INSTALL a new C-CM. REFER to Cruise-Control Module (C-CM) Service and Repair. CLEAR the DTCs. TEST the system for normal operation.
