(reedswitch)isateither middleOrhigh speed
[approx24km/h (15 mph)ormorelTherefore_
when the vehicle is driven at middle or high speeds
whiletheABSis operating,acceleratoropener
solenoid valve No.2 is turned ON to introduce the
vacuum produced by the vacuum pump to chamber
of the accelerator opener

This makes the accelerator lever open a little (to the
position equivalent to when the engine is running at
1,900rlminwithnoload) ,therebypreventing
excessive engine braking effect: In other cases, this
