- HINT:
- ·
As a waterproof connector is used for the brake actuator assembly, voltage and waveform inspections cannot be performed with the connector connected.
- ·
Use the GTS to read data and perform Active Tests when inspecting the operation and communication status of the brake actuator assembly.
