45-21-01 – Autonomous Emergency Braking (AEB) (U.S. Only)
Transaction No:
2062957/4
Release date:
12/18/2023
Technical Background
The customer reports that the vehicle performed an unwarranted Autonomous Emergency Braking (AEB).
Ensure that the customer is familiar with the various Driver Assist systems and the system limitations via
the owner’s manual and videos available at knowyourvw.com.
Review of the Self Study Programs (SSP 890253 –Driver Assistance Systems, SSP 860193 - Adaptive
Cruise Control and Lane Change Assist, and new model SSPs for specific Driver Assist information for
that model), is recommended before performing this TSB.
Participation in the instructor-led training 860292 - Volkswagen Driver Assistance Systems is
recommended before performing this TSB.
Production Solution
No current production solutions.
Service
1. Perform preliminary diagnosis
1a. Preliminary Inspection:
Prior to connecting a scan tool, perform the following checks:
 Perform a vehicle walk around to check for signs of damage or misalignment from previous damage or
repair (i.e. bumpers, front grill, front VW emblem, windshield inc. interior mirror and sensor mounting).
Areas of concern should be inspected/repaired and system retested before continuation of this
Technical Bulletin.
 Check the trailer hitch (on equipped vehicles) for signs of trailer or hitch carrier usage. Use of a trailer
or hitch carrier that does not connect to the vehicle electrical system can cause a change in vehicle
ride height. This change can cause a temporary misalignment of the front radar sensor.
 Continue to step 1b.
1b. Scan tool diagnosis:
Connect the scan tool and scan the vehicle for any stored fault codes.
 If any stored faults are found, follow the test plan and perform repairs as necessary. After repairing the
concern, retest the vehicle. If the concern persists, continue to step 2. If the issue is no longer present,
return the vehicle to the customer.
 If no fault codes are stored continue to step 2.

Continue to Step 3. Data Collection
3. Data Collection:
Perform the test plan “Technical Product Information” in O.D.I.S. Service.
To locate the test plan:
 Select self test -> Diagnostic capable system -> 0013 Distance control (ACC) -> Technical Product
Information.
 Once the test plan is complete, save the GFF log to the desktop as an .html file.
Gather MVB information (via guided functions):
 Select O.D.I.S. on the OBD screen.
 Click on each module one at a time:
 AW 13 - Distance Control module/Adaptive Cruise Control
AW 8B - Distance Control Module 2/Adaptive Cruise Control 2 (where equipped)
 AW A5 - Front Sensors Driver Assistance System (where equipped)
 AW 17 – Instrument Cluster
 Use the dropdown box just above the module list, select MVB and then green forward arrow.

Open the saved log and select expand all so all tabs are open. Scroll through the log to locate the Test
step:J428pro information.
The data should appear similar to the following:
 Ensure that the current vehicle date/time are correct under Control module data: -J285- Instrument
Cluster Control Module (take note for later use if incorrect and then set correctly)
 Using the information under “Control module data:-J428- Control Module for Adaptive Cruise Control”
refer to the attached example and chart below:

5. Checking Misalignment Angle
 Check for customer usage of hitch carriers or frequent travel with vehicle loaded (refer to customer
questionnaire) as this can affect the misalignment angle.
 Check the MVB misalignment angle in AW13. Ensure the angle is within specification (-0.8° to +0.8°).
If outside the specifications, perform a calibration of the -J428- using vehicle appropriate test plan and
retest the system. Refer the customer to the Owner’s Manual and www.knowyourvw.com for an
explanation of the system operation and limitations.
 If no issues are found with the misalignment angle and no evidence of vehicle hitch use is suspected
continue to Step 6.
6. Engineering Review
Necessary information for engineering review:
 Obtain a photo of the Grill, Emblem, Bumper Cover, windshield mounted camera, and the back of the
Radar Sensor, which will show all printed detail on it.
 Obtain photos of the -KX2- Instrument Cluster and of the Radio while the engine is running. The
photos should include the vehicle’s current time and date (with a clock next to it) as well as the
mileage.
 A google maps printout (screenshot of aerial view and street view) of the location noted by the
customer with GPS coordinates visible (make sure the red flag on the map is located on the site noted
by the customer).
 Open a VTA ticket and attach all information gathered:
 All GFF logs (including -J428- test plan and all MVBs).
 Completed questionnaires filled out by the customer for each event they say occurred.
 All required photos (see examples below).
 The Helpline Consultant will review the information is complete before requesting engineering review.
