Refer to Wiring Diagram Set 31, Cruise Control for schematic and connector information. Diagrams By Number
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 unit, determines the distance and relative speed of the vehicle that is in the path of travel. The C-CM (Cruise-Control Module) can be aligned both vertically and horizontally. The vertical alignment is a manual procedure carried out by adjusting the C-CM (Cruise-Control Module) adjustment screw. The horizontal alignment is a software procedure that is carried out internal to the C-CM (Cruise-Control Module). The C-CM (Cruise-Control Module) 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 (Cruise-Control Module) as a continuous memory and on-demand DTC if the C-CM (Cruise-Control Module) 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 (Cruise-Control Module) out of alignment
PINPOINT TEST N : DTC U0300:55
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
N1 INSPECT THE C-CM (Cruise-Control Module) BRACKET
- Inspect for damage to the C-CM (Cruise-Control Module) bracket.
Is the C-CM (Cruise-Control Module) bracket damaged?
Yes
REPAIR or REPLACE the C-CM (Cruise-Control Module) bracket as necessary. REFER to Cruise-Control Module (C-CM) . TEST the system for normal operation.
No
GO to N2.
N2 CARRY OUT THE VERTICAL AND HORIZONTAL ALIGNMENT
- Carry out the alignment procedures for the C-CM (Cruise-Control Module). Refer to Cruise Control Module (C-CM) (with Sensor) Adjustment Adjustments.
Does the C-CM (Cruise-Control Module) 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 (Cruise-Control Module). REFER to Cruise-Control Module (C-CM) . CLEAR the DTCs. TEST the system for normal operation.
