BENDIX EC-60 ABS-ATC STD-PREM CONTROLLERS User Manual

9
per mile is 426, and the maximum is 567. The ECU will set
diagnostic trouble codes if the number or revolutions are
out of this range.
In addition, the size of the steer axle tires compared to the
drive axle tires also has to be within the ABS system design.
To avoid diagnostic trouble codes, the ratio of the effective
rolling circumference of the steer axle, divided by the effective
rolling circumference of the drive axle, must be between
0.85 to 1.15.
ABS PARTIAL SHUTDOWN
Depending which component the trouble code is detected
on, the ABS and ATC functions may be fully or partially
disabled. Even with the ABS indicator lamp on, the EC-
60
™
controller may still provide ABS function on wheels
that are not affected. The EC-60
™
controller should be
serviced as soon as possible.
