ABS SOLENOID VALVE

• Select “Up”, “Keep” and “Down”. Then use screen monitor to check that solenoid valve operates as shown in

the table below.

*: On for 1 to 2 seconds after the select, and then Off.
NOTE:
A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is an
operation for checking.

ABS SOLENOID VALVE (ACT)

• Select “Up”, “ACT UP” and “ACT KEEP”. Then use screen monitor to check that solenoid valve operates as

shown in the table below.
