38C
II - REFITTING OPERATION FOR PART
CONCERNED
aRefit the braking computer (2) , holding it by its edge.
aRefit the braking computer bolts on the pressure
modulation unit.
aTorque tighten the braking computer bolts (3 Nm)
using the (Mot. 1608).
III - FINAL OPERATION.
aRefit the entire hydraulic unit (see 38C, Anti-lock
braking system, Hydraulic brake unit: Removal -
Refitting, page 38C-2) .
aConnect the battery (see Battery: Removal - Refit-
ting) (MR 411, 80A, Battery).
aBleed the braking circuit (see 30A, General infor-
mation, Braking circuit: Bleed, page 30A-4) .
aConfigure the tachometric index using the Diagnos-
tic tool (see Fault finding - Replacement of com-
ponents) (MR 413 Fault finding, 38C, Anti-lock
braking system).
aClear any faults stored by the braking computer.
aCarry out a road test to confirm the repair.Note:
Do not try to force the braking computer into
place when refitting; it should fit in without any
resistance.
Note:
When a new braking computer is being fitted,
remember to attach the interconnection fork (4)
between the pressure modulation unit and the
braking computer.
