Mercedes-Benz Part 573 Submission
Original Submitted to Portal October 23, 2020
Chronology-Only section
Supplement to Original Submission
Chronology of Defect/Noncompliance Determination
In January 2020, MBAG launched initial investigations based on a finding on an internal vehicle that experienced a loss of the electric power steering assist. It was found that this vehicle had a damaged wiring harness which allowed moisture ingress into the wiring harness. The moisture subsequently entered into the steering control unit which resulted in the loss of the electric power steering assist. An analysis was initiated with the supplier. The initial results of the analysis indicated a deviation in the cutting process of the wiring harness at the supplier.
Further investigations were started to understand whether there was a more widespread possibility for damage to other wiring harnesses and if so, the extent of potential damage on the wiring harness and possibility of moisture ingress. During this process, the production plant reported additional vehicles that were found to have experienced a loss of electric power assist. MBAG reviewed its warranty claims and other field data and did not find any reports that were potentially related to this issue.
These findings indicated that if a vehicle were to have a damaged wiring harness, the part would have already been installed having prior damage rather than incurred during the production process.
MBAG reviewed its supplier’s production process in detail to understand the point in the process at which the wiring harnesses may have been damaged. The damaged wiring harnesses of vehicles identified at the production plant were reviewed in comparison to the supplier’s processes.
As a result, the root cause could be limited to a production deviation caused by incorrect parameters set in the process of cutting the wiring harnesses at the supplier. A correction of the process was immediately implemented at the supplier in February 2020.
Starting in February 2020, MBAG also analyzed the potential for vehicles in the field to have departed the production plant with a potentially affected wiring harness. In parallel, the range of potentially affected vehicles in the field was determined up to July 2020 based on logistics documents and supplier information.
Furthermore, a detailed analysis of the potential consequences of the damaged wiring harness was started. Other than the short-term consequences, an estimation of the risk over time for the affected vehicles was performed and compared to experiences and existing test results.
In October 2020, MBAG determined that a potential safety risk cannot be ruled out.
SEOCONTENT-START
Check/test procedure
1. Switch off ignition and store vehicle key at least 2 meters away from vehicle.
2. Remove lower engine compartment lining.
For basic data for model 253, see AR61.20-P-1105LW;
3. Release and remove both connectors at steering control unit (figure 1).
4. Check connector of red power supply cable and brown ground cable for moisture. In the case of moisture, make detailed photos, create the steering (N68) control unit log and clarify the further repair procedure via PTSS case.
5. Expose wiring harness up to a length of 300 mm from the connector. This can be achieved by sliding back the protective hose. There are two different cable routings (figure 1).
Figure 1 (Routing in cable duct) (Routing in protective hose) In the case of routing in cable duct
1. Release cable duct.
2. Mark position of cable ties so that these are located at same position during the installation.
3. Release cable ties (from the connector, the first four) and remove lines from cable duct.
4. Slide back the protective hose for check purposes. In the case of routing in the protective hose without cable duct
1. Mark position of cable ties so that these are located at same position during the installation.
2. Release cable ties (starting from the connector, the first two) and slide back the protective hose.
3
P-RC-2020110012
6. Check the red power supply cable and brown ground cable 300 mm up to 320 mm after the connector for cuts in the insulation (figure 2). Move the red power supply cable and brown ground cable in all directions for check purposes. The red power supply cable and brown ground cable may not be damaged.
Figure 2 (NOT OK) The following damage may be present.
a. Brown ground cable damaged: Perform work procedure A.
b. Red power supply cable or both cables damaged: Perform work procedure B.
c. Red power supply cable and brown ground cable not damaged: End measure. The findings from the check/test procedure must be recorded in writing in the workshop order and
then stored in a tamperproof manner.

P-RC-2020110012
Work procedure A
IMPORTANT: The original FlexRay cable installed in the vehicle remains in the vehicle and may in no case be damaged.
Replace brown ground line If the brown protective covering is damaged but no leads of the line can yet be seen, a quick test is not necessary. The brown ground line must be replaced. Only if the leads of the brown line can be seen:
1. Check connector couplings of the red power supply cable and brown ground line for moisture. Only if there are drops of water in the plug within the sealed area : Take detailed pictures, create a control unit log for the steering (N68), and clarify further repair procedure using a PTSS case. The red seal may appear a bit “wet” (in Figure 3 (A)). This is residual oil from manufacturing and is normal. If this is the only area that looks “wet” No PTSS case needs to be created in this case.
Figure 3 If no moisture can be detected near the contacts, a quick test with connected steering must be performed.
If the fault code B210F00 is stored in the steering control unit (N68), this can be ignored during the evaluation. This fault code has nothing to do with the current topic. This fault code arises if the workshop removes the power connector of the steering and the steering is not yet in sleep mode and/or is in idle state. Solely in the case of the following two fault codes P063500 or C159800 in the steering control unit,
a PTSS case must be created. Create steering (N68) control unit log and clarify the further repair procedure via PTSS case. If neither of the two indicated codes is stored, then only the brown ground line must be replaced. If the protective covering is damaged but no strands of the line can yet be seen, a quick test is not necessary. The brown ground line must be replaced.
1. Dismount right front wheel.
2. Remove fender liner in front fender (AR88.10-P-1300LW).
5
P-RC-2020110012
3. Disconnect ground line at power connector at new and old wiring harness. The primary lock can be opened by moving the pink lug outwards (figure 4).
4. Disconnect plug contact (figure 5).
Figure 4 Figure 5
5. Open all cable ties at new wiring harness and remove both the FlexRay and the power supply line.
6. Unscrew cable lug of old ground line, cut off and wrap in fabric tape (figure 6).
Figure 6

P-RC-2020110012
7. Screw new ground line onto ground point, connect into existing power connector and route parallel to existing line.In the case of routing in the protective hose, it must be ensured that the new ground line is also installed with the delivered protective hose. In the case of routing in the cable duct, an identical routing to the previous wiring harness must be ensured.
8. Assemble in reverse order.
Work procedure B
IMPORTANT: The original FlexRay cable installed in the vehicle remains in the vehicle and may in no case be damaged.
Replace red power supply line If the red protective covering is damaged but no leads of the line can yet be seen, a quick test is not necessary. Both lines must be replaced. Only if the leads of the red power supply cable can be seen:
1. Check connector couplings of the red power supply cable and brown ground line for moisture. Only if there are drops of water in the plug within the sealed area : Take detailed pictures, create a control unit log for the steering (N68), and clarify further repair procedure using a PTSS case. The red seal may appear a bit “wet” (in Figure 7 (A)). This is residual oil from manufacturing and is normal. If this is the only area that looks “wet” No PTSS case needs to be created in this case.
Figure 7 If no moisture can be detected near the contacts, a quick test with connected steering must be performed.
If the fault code B210F00 is stored in the steering control unit (N68), this can be ignored during the evaluation. This fault code has nothing to do with the current topic. This fault code arises if the workshop removes the power connector of the steering and the steering is not yet in sleep mode and/or is in idle state.

P-RC-2020110012
Solely in the case of the following two fault codes P063500 or C159800 in the steering control unit
a PTSS case must be created. Create steering (N68) control unit log and clarify the further repair procedure via PTSS case. If neither of the two indicated codes is stored, then only the red power supply line must be replaced. If the protective covering is damaged but no strands of the line can yet be seen, a quick test is not necessary. The red power supply line must be replaced. In the case of damage to the red power supply line, the brown ground line is always also replaced.
1. Dismount right front wheel.
2. Remove fender liner in front fender (AR88.10-P-1300LW).
3. Unscrew ground line of steering (figure 6, see work procedure A)
