Complaint:
Blind Spot Assist inoperative.
Cause:
Water ingress into the rear short-range radar sensors.
Notes on diagnosis:
Model series 164 with code 234 (Blind Spot Assist):
•
Malfunctions on the engine compartment CAN (CAN C) are possible
•
In control units on the CAN C, CAN communication errors may be logged with the rear short-range radar sensors (IRS-HLA B29/4 and IRS-HRA B29/5 control units).
•
Diagnostic communications with control units on the CAN C may not be possible.
Model series 212/218 up to code 800 (Model year 2010) with code 234 (Blind Spot Assist):
•
Malfunctions on the sensor CAN (CAN S) are possible
•
In the radar sensors control unit (N62/1), CAN communication errors may be logged with the rear short-range radar sensors (B29/6 and B29/7).
•
Communications with control units on the CAN S may not be possible.
Model series 212/218 as of code 801 (Model year 2011) with code 234 (Blind Spot Assist):
•
Malfunctions on the front end CAN (CAN G) are possible
•
Control units on the CAN G may exhibit CAN communication errors with the rear short-range radar sensors
(IRS-HLA B29/4 and IRS-HRA B29/5 control units).
•
Diagnostic communications with control units on the CAN G may not be possible.
Model series 212/218 with code 237 (Active Blind Spot Assist):
•
Malfunctions on the sensor CAN (CAN S) are possible
•
In the video and radar sensor system control unit (N62/2), CAN communication errors may be logged with the
rear short-range radar sensors (B29/6 and B29/7).
•
Communications with control units on the CAN S may not be possible.
Remedy:
1.
2.
3.
4.
Remove rear bumper.
Remove rear short-range radar sensors, check connector/contact for corrosion and repair if necessary.
Make additional holes or cutouts in the brackets for the rear short-range radar sensors (see attachments).
Install short-range radar sensors with additional silicone sealing (see parts ordering note).
