Object Detection System: Adjustments Cadillac SRX II facelift

Calibration (without UGN)

The calibration process for the front view camera system is necessary when a front view camera module is replaced by a new one. This process shall not be required when only replacing the windshield and the front view camera module has been mounted again properly. This process shall be completed within 3-5 minutes when the correct driving conditions are met. If conditions are not met correct, the front view camera module shall continuously run the service point calibration until successfully completed. This process shall work across ignition cycles and shall not be required to be re-initialized at start up. If the Lane Departure Warning Switch is pressed during calibration, the indictor will flash momentarily and then stay out - this is normal operation.

The calibration procedure will start automatically after SPS programming is complete. During this time the Lane Departure Warning amber indicator will illuminate.

To calibrate the front camera, operate the vehicle in the following conditions until the calibration is complete

1. Clean windshield.
2. Avoid lane changes.
3. Maintain vehicle speeds between 56-90 km/h (35-56 MPH).
4. Ensure the road contains visible references (well defined lane markings, curbs, etc.).

Once the procedure is complete, the amber indicator will turn off. Shortly after the green ready to assist light should turn on as long as all conditions are met for normal operation. The system is then ready to assist.

Calibration (with UGN)

The calibration process for the front view camera system is necessary when a front view camera module is replaced by a new one. This process shall not be required when only replacing the windshield and the front view camera module has been mounted again properly. This process shall be completed within 10-30 minutes when the correct driving conditions are met. If the Lane Departure Warning Switch is pressed during calibration, the indictor will flash momentarily and then stay out - this is normal operation.

Note. Calibration is not required if the existing module was reprogrammed. This procedure only needs to be conducted if the module was replaced.

Once SPS programming is complete, it is necessary to initiate the calibration using a scantool. During this time the "Service Driver Assist" service message will be displayed.

Note. It is necessary to have the scantool connected during the entire process. Do not back out of the screen or press any other buttons.

To calibrate the front camera, operate the vehicle in the following conditions until the calibration is complete

1. Clean windshield.
2. Avoid lane aggressive and frequent lane changes. Occasional lane changes are preferred.
3. Maintain vehicle speeds between 56-120 km/h (35-75 MPH).
4. Ensure the road contains visible references (well defined lane markings, etc.).

Once the procedure is complete, the service message will turn off and normal operation will resume. Shortly after the green ready to assist light should turn on as long as all conditions are met for normal operation. The system is then ready to assist.

If Slow to Calibrate

The ideal calibration condition is driving on a 2 lane divided highway with markings on both sides of the lane. One or more of the following conditions may increase the length of time required to complete the self-calibration procedure

1. Heavy traffic
2. Stop and go traffic
3. Mountain roads
4. Curves in roadway
5. Poor contrast lane markings
6. Botts' Dots type lane markings
7. Operating the vehicle at speeds greater than recommended
8. Driving through snow or fog, or driving directly into the sun
9. Camera not properly installed. Verify it is snapped into tabs and is secure. Refer to «Front View Camera Replacement (With UFL)»(ref-644761-S33560737732014072300000) , «Front View Camera Replacement (With UGN)»(ref-644761-S34758800472014072300000) .

No Calibration

Conditions that will prevent completion of the self-calibration procedure

1. Dirty windshield glass or obstruction on windshield
2. Operating the vehicle with speed less than 56 km/h (35 MPH)
3. No visible lane markings
4. Severe weather where lane markings cannot be seen
5. Camera not properly installed. Verify it is snapped into tabs and is secure. Refer to «Front View Camera Replacement (With UFL)»(ref-644761-S33560737732014072300000) , «Front View Camera Replacement (With UGN)»(ref-644761-S34758800472014072300000) .

Radar Sensor Module - Long Range Calibration

After replacing and programming the Long Range Radar Sensor Module, it is necessary to perform a calibration procedure to align the radar. This is indicated to the technician by DTC B101E 4B. Calibration is performed while driving the vehicle with the scantool connected. Calibration is initialized using a scantool and the scantool must remain connected until calibration is complete. During this time the "Service Driver Assist" service message will be displayed. Once the procedure is complete, the service message will turn off and normal operation will resume.

Calibration is not required if the existing module was reprogrammed only. Calibration needs to be conducted if the module was replaced or removed and re-secured.

If calibration is not successful, it could be due to improper driving environment, module and bracket assembly bent out of position or incorrect module mounting. A typical driving environment is usually sufficient to calibrate the module within 10-30 minutes. The module needs to be mounting properly in the bracket and aimed straight ahead within +/- 3 degrees.

Calibration Procedure

1. Verify no other DTCs except for B101E 4B Electronic Control Unit Software are present. If other DTCs are present Refer to service information and repair as necessary. If no other DTCs are present
2. Prior to driving the vehicle make sure the surface in front of the radar (Cadillac emblem) is clean. Also verify the mounting area is not damaged and allows the module to face the intended direction.
3. Prepare scantool to be mobile for Long Range Radar Calibration driving phase. The scantool needs to stay connected during the driving phase of the calibration.
4. Engine running.
5. Initiate calibration using Long Range Radar Sensor Module Learn in the scantool. The driver information display will display "Service Driver Assist" message during calibration. NOTE: Do not back out of screen or press any other buttons until the calibration is complete.
6. Drive the vehicle within the following conditions for 10-30 minutes or until calibration is complete. The "Service Driver Assist" message will turn off when calibration is complete. Drive at speeds greater than 56 kph (35 mph) Minimize tight curves Avoid extreme acceleration or deceleration Follow one or multiple vehicles. (typical vehicle traffic is sufficient, but vehicles 30m - 50m (100 -165ft) away are most effective at decreasing the calibration time) Drive in an environment that has stationary objects on the side of the road (street signs, guard rails, mail boxes, fences, etc)
7. Verify proper calibration by observing that the "Service Driver Assist" message turns off within 10-30 minutes of normal driving. If "Service Driver Assist" message fails to turn off Verify correct operating conditions were met If incorrect driving environment, refer to «If Slow to Calibrate»(ref-644761-S35731525522014072300000) and repeat calibration procedure following recommended operating conditions. If correct driving environment Verify DTC B390C 66 Incorrect Mounting is not set If B390C 66 is set Refer to «DTC B390C»(ref-644761-S42314816012014072300000) . If B390C 66 is not set If "Service Driver Assist" message turns off
8. Drive at speeds greater than 40 kph (25 mph) and verify engagement of Adaptive Cruise Control (cruise control icon will change from white to green) If Adaptive Cruise Control will not engage Check vehicle for DTCs and correct as required. If Adaptive Cruise Control engages
9. All OK.

The ideal calibration condition is driving on a freeway or two lane road with medium traffic. One or more of the following conditions may increase the length of time required to complete the self-calibration procedure

1. Heavy traffic - following too close behind vehicles for long periods (more than 40 min)
2. Stop and go or very slow traffic
3. Mountain roads
4. Constant sharp curves in roadway
5. No traffic - if no traffic is available, may need to add vehicle ahead to support calibration
6. Limited or no stationary structures on side of the road - need structures such as street signs, guard rails, mail boxes, parked cars, etc.
7. Driving in tunnels
