Introduction
The Dynamic Laser Cruise Control system has two cruise control modes:
1. Constant Speed Control Mode
his mode is used on conventional cruise control systems. It is also called “fixed speed” control mode and is used for
T
cruising at fixed speeds.
2. Vehicle-to-Vehicle Distance Control Mode
In this mode, the cruise control system uses a laser sensor to detect a vehicle in front of you and measures the
vehicle-to-vehicle distance. The detection range of the sensor is about 394 ft (120m) ahead.

dynamic laser cruise control sensor and covers the key points
of laser sensor adjustment.
How the laser sensor works:

Main Components
ECM
Throttle Body
• Throttle Control Motor
• Throttle Position Sensor
Laser Receiving
Portion
Laser Radar Sensor
• The laser sensor emits a laser beam toward the preceding
vehicle.
Note
• The laser sensor receiving portion detects the light reflected
from the preceding vehicle.
Help
• The ECU inside the laser sensor then takes the light received
by the sensor and converts it into an electrical signal.
Click
• From this electrical signal, the preceding vehicle’s distance
and angle can be determined.
Skid Control ECU
Park / Neutral Position Switch
EXTERIOR COMPONENTS
Laser Emiting Portion
Always keep the sensor clean to ensure the vehicle-tovehicle distance control operates properly. Obstructions
such as snow, ice or plastic objects cannot be detected by
the obstruction sensor and may cause the dynamic laser
cruise system to cancel.

Note
Preparation Procedure
Help
• Careful preparation is key to accurate adjustment of the cruise control laser sensor.
• Carefully read and follow the steps outlined in this guide to obtain the most accurate measurements.
• The time you spend making precise measurements will ensure proper reflector SST placement and sensor adjustment.
Click
Vehicle Pre-Checks
Tip
• Refer to the tire pressure information label located on the door jamb for proper tire inflation pressure or refer to the Owner’s Manual.
• Make sure that the trunk and passenger compartment is unloaded.
• Clean the light emitting and light receiving portions of the laser sensor.
• Check that the laser sensor, bumper reinforcement, etc., are installed properly.
From your roll of string, cut 2 separate strings to the following lengths:
•String #1 - 49 ft (15m) - to be used in Step 4
•String #2 - 3.3 ft (1m) - to be used in Step 7

1. Connect Techstream to DLC3, then turn power ON.
2. Turn the ignition switch to ON.

6. Push the Cruise Control Main switch to ON.
If the “UPPER/LOWER SIDE” and “LEFT/RIGHT SIDE” values change
when moving the reflector SST to the left and right, a laser beam signal
is being sent by the sensor emitter and then reflected back to the sensor
receiver by the SST.
