Module Programming: Calibration
The following procedure explains how to calibrate the Forward Facing Camera HALF (FFCM-HALF) when replacing the FFCM-HALF (a replacement FFCM-HALF is not factory calibrated). This procedure should also be used when the windshield is replaced.
Perform the following checks and setup prior to performing the calibration procedure:
- Confirm that the vehicle is unloaded (no luggage or extra weight being carried).
- Check and correct the tire pressures as needed.
- Check that the windshield is free of damage, is clean and that there are no impediments to the vision of the FFCM-HALF.
- Place the vehicle and the ADAS Calibration system tool on level ground and in good light.
- The vehicle has to be centered to the board.
- Align the wheels to the longitudinal axis of the car.
The following setup procedure are to zero the ADAS Calibration System tool at the following locations:
- Target Bracket
- Yaw Adjustment
- Lateral Adjustment
CALIBRATION PROCEDURE
- Using special tool (special tool #2076800080, ADAS Calibration System) place the Calibration Board 1.70m from the FFC/HALF (tape can be used)
- Use the calibration boards laser measuring tool to position the calibration board 1.70 meters (1700 mm) from the FFC/HALF module (1).NOTE:
When using the center laser measuring tool to set the correct distance from the target to the FFC/HALF, First measure the distance from the FFC/HALF to the bumper and the distance from the target to the laser. With the laser measuring tool aimed at the bumper, the distance will be 1.70 meters (1700 mm) minus the sensor to bumper measurement plus (front of the laser to the target).
- Use the two side laser measuring tools aimed at similar spots on the vehicle and attempt to reach equal values.NOTE:
Use masking tape (1) if necessary to provide a target for the lasers.
- Once the preliminary distance has been set, screw down the calibration tool legs to secure the tool in place.
- Install the wheel clamp with laser target board (2) to each rear wheels (1).
- Lower the calibration board to the same level as the laser targets on the rear wheel clamps, which should be centered to the wheel hub of the rear wheel.
- Turn on the lasers and align them to the rear wheel target boards on each side. The values on both side should be equal. If they are not, use the lateral adjustment knob on the calibration tool to adjust it left or right until equal values are achieved. This fully centers the calibration tool to the vehicle.
- Fully open the mirror covers to expose the mirrors.NOTE:
Fully open the mirror covers to minimize wear and tear on the mirror cover hinges.
- If needed, adjust the lasers on the wheel clamps in order for the lasers to reflect back properly to the target.
- After the lasers are reflecting back to the target, compare the values on the left and right rear wheel clamps and then use the Yaw adjustment knob to equal out the values on each target board.
- Connect the diagnostic scan tool and start the vehicle. The system must not be activated.
- Navigate to the HALF and then select the Misc. Functions tab.
- Select and perform the Service Single Pole Calibration procedure.
- During the Single Pole Calibration procedure, the scan tool will ask you to move the target back 1 meter (1000 mm) from the setup position. The suggestion is to tape a spot on the ground under the bumper and move the vehicle instead. This will avoid having to square and center the calibration tool a second time.NOTE:
Confirm the steering wheel is centered before moving the vehicle.
If during operation, the LDW+ system releases alerts inconsistent with the actual driving conditions (e.g. the vehicle properly between lanes but notice the crossing lane), the system must be calibrated again.
