VSC (VDC) Control Module and Hydraulic Control Unit (VSCCM & H/U): Installation

CAUTION:

When installing the VSCCM & H/U to the VSCCM & H/U bracket, make sure that there is no oil adhered to the nuts and the threads of VSCCM & H/U. If the oil is adhered, degrease it carefully before tightening.
Connect the VSCCM & H/U connector securely.
When the hydraulic unit assembly VSC (VDC) has been replaced, be sure to perform the module registration.

Attach the bracket COMPL hydraulic unit VSC (VDC).
Tightening torque:

33 N.m (3.4 kgf-m, 24.3 ft-lb)
Using a new damper, washers, and nuts, install the hydraulic unit assembly VSC (VDC) to the bracket COMPL hydraulic unit VSC (VDC).
Tightening torque:

7.5 N.m (0.8 kgf-m, 5.5 ft-lb)
Install the brake pipe using a flare nut wrench and a crowfoot wrench.
NOTE: If the work can be performed with the front and back sides reversed, it is also possible to use a 6-point crowfoot wrench.

Tightening torque:

Calculation formula

T1 = 15 N.m (1.5 kgf-m, 11.1 ft-lb) x L1/(L1 + L2)

T2 = 19 N.m (1.9 kgf-m, 14.0 ft-lb) x L1/(L1 + L2)

T: Reading of the torque wrench

L1: Effective length of the torque wrench

L2: Effective length of the crowfoot wrench

NOTE: If the effective length of the tool used is unknown, consult the manufacturer of the tool.
