- 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.
b.
Measure the voltage or resistance according to the value(s) in the table below.
