display high exhaust temperature fault E4, while the IDU will display the specific faulty compressor.
For example, when high exhaust temperature protection is enabled on compressor 2# of module
3# of the ODU, IDUs will display E4 and the module will display E6, indicating that high exhaust
temperature protection is enabled on compressor 2#.
