TIDEP-01032: Is there any documentation supporting the resistance between the metal casing of the chassis controller used in automotive electronics and the ground plane of the circuit board?

您好，

 方便用图示详细说明吗？

metal case →──┬─── resistor（1MΩ）───-┳── PCB GND  
              └─── capcitor（10nF）───┛

Is there any documentation supporting the resistance between the metal casing of the chassis controller used in automotive electronics and the ground plane of the circuit board?

If this resistance was 0Ω, what risks would be caused?

Is that clear please?

OR is there any document about "shielding grounding" that "Use a 10MΩ resistor and 10nF capacitor in parallel from shield to PCB ground"?

OR  is there any document about "Chassis-to-PCB Ground Connection" that "a high-value resistor (1MΩ to 10MΩ) in parallel with a capacitor (typically 10nf) is required between the metal enclosure and PCB ground."

This circuit of ECU is used in the system of chassis after all

 H8001 is the locating hole connected with metallic case，R8005 is the resistor between metallic case and GND.

Is there any documentation supporting the resistance between the metal casing of the chassis controller used in automotive electronics and the ground plane of the circuit board?

If this resistance（R8005） was 0Ω, what risks would be caused?
