Checking Blind Spot Information System (BLIS)
Checking the "Blind Spot Information System" (BLIS)
Checking text message in Driver Information Module (DIM)
Hint: By holding in the trip odometer reset button for 10 seconds the text ID for the relevant text message is displayed in the Driver Information Module (DIM).
- Start the car.
- Depress the trip odometer reset button. Hold the button depressed until the relevant text ID is displayed in the Driver Information Module (DIM).
- Scroll between the messages in the Driver Information Module (DIM) by pressing the READ button.
Choose below, depending on text message.
1. Text-ID 183. The message is removed from and incl. structure week 200940.
2. Text-ID 110.
3. Text-ID 109 or no relevant message.
Select an alternative.
1 - Reduced function
2 - Camera blocked
3 - Service need
-------------------------------------------------
Reduced function
The text message means that the system for the moment has some difficulties in functioning satisfactorily. In general, this depends completely on external factors and applies especially at dawn and dusk when the system cannot decide if it is to use day mode or night mode. The message is removed from and incl. structure week 200940.
Other conditions when the fault message may appear:
- Driving in total dark for more than 10 minutes.
- Heavy rain or snow.
- Moisture or dirt on the camera lens.
- Very powerful light, which saturates the camera image.
Corrective actions
- Clean the camera lens. Use a soft rag or moist sponge, so that it is not scratched.
- Check the heater in the lens by spraying on a thin layer of frost using freeze spray. Make sure that the mist disappears. Lens temperature should be 70 - 75 °C. If the heater does not work, replace the rear-view mirror in question.
- If the fault message does not disappear, turn off the engine, remove the key, and start again.
- Inform the customer of the system's limitations.

Camera blocked
This text message indicates that the camera lens is blocked; or, a camera may have reported "reduced function" for a longer time period than 10 minutes. The light-emitting diodes indicate constant an object in the "dead angle".
Conditions that may cause the text message:
- Low standing sun means that it will be light on one side and dark on the other side of the vehicle.
- Heavy rain or snow.
- Moisture or dirt on the camera lens.
Corrective actions
- Remove the key from the ignition switch.
- Clean the camera lens. Use a soft rag or moist sponge, so that it is not scratched.
- Check the heater in the lens by spraying on a thin layer of frost using freeze spray. Make sure that the mist disappears. Lens temperature should be 70 - 75 °C.
- If the heater works correctly, inform the customer that the system as a whole and about the system's technical limitations. See Design and Function for more information.
- If the fault message does not disappear, turn off the engine, remove the key, and start again.
- If the heater does not work, replace the rear-view mirror in question.

Has any rear-view mirror been replaced?
Yes - Verification
No - Information
-------------------------------------------------
Service need
The fault message may be due to communication problems internally in one of the cameras, or between camera and the vehicle's other systems. It may also be due to one of the diodes being short-circuited.
- Read off diagnostic trouble codes (DTCs). Troubleshoot and take care of diagnostic trouble codes that may be related to the above problems.
- Drive a short test-drive and check if text-id 109 is seen in the driver information module. Speed during the test-drive must mainly be above 10 km/h and the test-drive should include at least one stop where the start key is removed from the ignition.
- If the text message is not seen, the system is fully functional. Then the customer complaint is due to technical limitations in the system. Inform the customer of the system's limitations.

Verification
- Drive a test-drive. Speed during the test-drive must mainly be above 10 km/h and the test-drive should include at least one stop where the start key is removed from the ignition.
- Check that the message in Driver information module (DIM) has disappeared and that the function works satisfactorily.
Is there a relevant text message?

-------------------------------------------------
Checking components and switches
- Switch off the engine.
- Check the heater in the lens by spraying on a thin layer of frost using freeze spray. Make sure that the mist disappears. Lens temperature should be 70 - 75 °C.
- Start the engine and check if the diodes on left and right side flash three times each.
- If any diode does not flash three times, check it.
Check the diode by measuring the resistance across it or connect it to voltage and check that it lights up.
- If the diode does not work, replace it.
- If the diode works, check all relevant connectors.
- If the heater does not work, replace the rear-view mirror in question. If no fault is detected, replace rear-view mirror.
