ACTUATOR TEST TABLE



note
  • ABS and ASC are operated by ASC-ECU.
  • When ASC-ECU is disabled due to the fail-safe function, the actuator test cannot be performed.
  • The actuator test can be performed only when the vehicle is stationary.
  • While the actuator test is performed, the ABS warning lamp flashes at a rate of 2 Hz.
  • While the actuator test is performed, the ASC indicator lamp and ASC OFF lamp illuminate.
  • After the actuator test has been performed, the brake warning lamp, ABS warning lamp, ASC indicator lamp, and ASC OFF lamp illuminate until the electric motor switch is turned to ON again or the communication between M.U.T.-III and ASC-ECU is terminated.
