The proposed conducted immunity tests on ESA communication lines. If possibe, layout and placement of dedicated circuit board also need provide.
As you suggested a brief discussion about the layout and the placement of dedicated circuit board has been added.
Thank you. 
Reviewer 2 Report
1. For an overview article, only 10 references (of which 6 are IEC standards and two are technical documents) is too little. Extend the review to articles published in recent years in High ranked Journals.
2. Some acronyms are not explained the first time they are used. The IEC and CEI (English and French acronyms) are also used. You should decide.
3. Many of the figures are taken exactly from the standards. Much stricter citations should be made.

All the acronyms have been explained and adjusted as you suggest. IEC has been chosen.
- Many of the figures are taken exactly from the standards. Much stricter citations should be made.
All the figure reported have been modified before adding them on the article.
Thank you.

Individual Report Result and Conclusion
1. Introduction
Recommendation:
In line 32 the different standards can be more specified.
As suggested standards have been specified.
2. Immunity Verification Methods
Recommendation:
First is generally the proposal to replace the naming for Equipment Under Test (EUT) by Device Under Test (DUT). This is more a standardized naming abbreviation.
As suggested EUT have been replaced with DUT.
Further general proposal is to add the related reference index to every standard used in the different sections.
As suggested all the standard references have been added.
Figure 1 can be enlarged.
As suggested the figure has been enlarged.
On picture 1 the recommendation is to describe the reason for the four different levels (why four, dependencies for applications, costumer request, region)
Levels have been specified as suggested.
In line 63 a proposal is to add an additional picture to describe the modulation index should be related to Fig. 3 instead Fig. 2.
As suggested a picture indicating the modulation index has been added (Figure 2).
In line 75 maybe it is possible to explain the reasons for the dimension limitations.
Thank you for the comment, dimensions are specified in the standard.
In line 79 the reasons for surge events can maybe assigned to a dedicated EV-component e.g., switching of main relay, converter, DC/DC, etc).
As suggested reasons has been specified.
Figure 2 can be splitted and enlarged.
As suggested the figure has been splitted and enlarged.
In line 91 it is recommended to implement values (table) for the communication speed.
Thank you for the comment, in line 104 has been added what is specified in the standard.
Figure 3 can be splitted and enlarged.
As suggested the figure has been splitted and enlarged.
Line 130 there are existing different kV-values, in automotive sector 4 or 6 kV are in use. The recommendation is to replace the pulse in figure 4 by a higher kV-value.
As suggested the Figure 4 (now Figure 5) has been changed reporting 4kV and 6kV ESD current waveforms.
Figure 4 can be enlarged.
As suggested the figure has been enlarged.
Further recommendation is to build in the Ref [4] in the ESD-section which is currently not in use.
As suggested the reference has been corrected.
For the ISO 7637 pulses the recommendation is to describe/implement for every pulse an example, which is the source event inside the car, e.g., load dump or jump start for a combustion engine car.
As suggested examples have been added.
Figure 5 can be splitted and enlarged.
As suggested the figure has been splitted and enlarged.
- Frequency Content of Disturbance Signals
In line 167 please implement a space between “Table 1” and “summarizes”.
Thank you for the comment, has been corrected.
4. Countermeasures against conducted disturbances on CAN Communications
In line 177 the proposal is to add a reference which describes the function and structure of CAN e.g., Robert Bosch Handbook.
As suggested the reference has been added.
In line 190 please implement the reference of a datasheet.
As suggested the reference datasheet has been added.
Line 242: The experience of CAN car application baud rate for High-Speed CAN is robust communication 500 kBaud. Maybe it makes sense to focus more on this Baud Rate.
As suggested 500 kBaud has been considered.
4. Conclusions
Consistent relationship to the focus aspect of the paper. As recommendation point of interest for further investigations are the effect of disturbing and the status of the DUT after the disturbing according to the tests and coming back to normal function condition.
Thank you for your comment, conclusion has been added.

Thank you.
Reviewer 4 Report
This overview reports some technical standards for immunity testing of electronic sub-components related to communication lines, and analyzes and discusses some available interference countermeasures applicable to control area network communication lines, as well as the design advantages and disadvantages of different types of filter and suppression circuit solutions. The content of this article is relatively mature, and the innovative content is not much. It is suggested to take Figure 9 as an example to give the specific parameters of the element in Figure 9, and add a simulation analysis result in Figure 9.

As you suggested, simulation results of the circuit in Figure 9 (now Figure 10) have been added, results are reported in Figure 11.
Thank you.
Round 2
Reviewer 1 Report
The proposed testing results can meet standard and make solutions. How about analyzing method? How about comparison with differential methods, not clear?
