J533 (address word 0019) and one of the external antenna’s for emergency call services.
Production Solution
Improved FAKRA connector.
Service
Overview
Tip: The location of the antenna, gateway, and connections vary by model. Be sure to consult the
applicable wiring diagram and installation locations for the vehicle you are working on.
Tip: Certain vehicles may have more than one external GSM antenna. Be sure to identify the antenna
circuit which applies to the DTC found in the data bus on board diagnostic interface, J533 (address word
0019).
Tip: When utilizing the VAS 6720 to perform a repair, ensure that the new connection is not under
tension. The cable may need to be extended utilizing the VAS 6720 to avoid placing tension on the
replaced FAKRA connector.
Tip: The information in the manual for the VAS 6720 regarding the ban of repairs on the emergency call
aerial wiring does not apply to repairs instructed by a TSB

Section 1:
Inspect connection at the data bus on board diagnostic interface, J533 (address word 0019):
1. Perform a visual inspection of the cable and connector.
Replace the contact utilizing the VAS 6720 if:
 There is tension on the cable. The cable should have some slack.
 The pin is bent or cracked.
 The cable is bent or damaged.
 The connector is not fully connected.

2. Perform a function check of the cable connector:
 View the applicable measured value from the
overview table above.
 Lightly pull, or push the applicable coaxial cable
along its respective X, Y, and Z axis (Figure 2).
 As the fault detection is not real time, hold the
cable in each position for 5 seconds and
observe the measured value (Figure 3).
Figure 2. Coaxial cable X, Y, and Z axis.
3. If a fault is detected during step 2 (“Open Circuit”), replace the contact on the wire harness at the data bus on
board diagnostic interface, J533 (address word 0019) utilizing the VAS 6720.
If no fault is detected, continue to the next section.

Section 2:
Inspect the connector at the Coupling Point in Interior, Center (TIM):
4.
Locate and gain access to the T2dkx and T2dk FAKRA connectors, located inside the TIM Coupling Point.
Consult the applicable wiring diagram and repair manual for the vehicle you are working on.
5.
Perform a visual inspection of the cable and connector at and between T2dkx and T2dx.
Replace both contacts utilizing the VAS 6720 if:
 There is tension on the cable. The cable should have some slack.
 The pin is bent or cracked.
 The cable is bent or damaged.
 The connector is not fully connected.
6.
Perform a function check of the cable connector:
 View the applicable measured value from the overview table above.
 Lightly pull, or push each side of the applicable coaxial cable along its respective X, Y, and Z axis.
As the fault detection is not real time, hold the cable in each position for 5 seconds and observe the
measured value (Figure 3).
7.
If a fault is detected during step 6 (“Open Circuit”), replace the contacts of both the T2dkx and T2dx
connectors utilizing the VAS 6720.
If no fault is detected, continue to the next section.
Section 3:
Perform Coax Overlay:
Tip: Vehicle Dashboard must be removed to complete repair. Consult the applicable repair manual for the
vehicle you are working on.
8.
If no fault was found in Section 1, and no fault was found in Section 2:
Replace the coax wire from the applicable emergency call module antenna to the data bus on board
diagnostic interface, J533 (address word 0019).
9.
Utilize the VAS 6720 to build a single coax wire from the emergency call module to the data bus on board
diagnostic interface, J533 (address word 0019).
 Do not split the new wire at the TIM connection between T2dkx and T2dk.
 Route the new wire along with the existing harness.
 Ensure that there are no sharp bends.
