Actuator Test Reference Table
Using scan tool, the following actuators can be forcibly operated:
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 light flashes at a rate of 2 Hz.
- While the actuator test is performed, the ASC indicator light and ASC OFF light illuminate.
- After the actuator test has been performed, the brake warning light, ABS warning light, ASC indicator light, and ASC OFF light illuminate until the electric motor switch is turned to ON again or the communication between scan tool and ASC-ECU is terminated.
