NOTE:
^ The skid control computer is integrated into the brake actuator ASSY and uses water-proof connectors. Therefore, voltage check and oscilloscope waveform checks for each terminal cannot be performed with the computer installed in the vehicle.
^ For the operation check and communication check of the skid control computer (brake actuator ASSY), use the data monitor and active test in the SSM3. Current Data Display & Save
