Hydraulic Control Assembly - Antilock Brakes: Description and Operation
The HCU consists of a valve block assembly, pump/motor assembly, and a fluid reservoir with a fluid level switch. The HCU is located on the left frame
rail forward of the master cylinder.
There are two Hydraulic Control Units. One for ABS only, and one for ABS and traction control combined. If a new HCU unit is installed with the
wrong type of CAB, the system will disable itself and a fault code will be stored.
