DESCRIPTION AND OPERATION
4.46 RANGE ROVER
ANTI-LOCK BRAKING SYSTEM (ABS)
DESCRIPTION
General
New Range Rover is equipped with Dynamic Stability Control (DSC) for enhanced braking
and stability control. Functions of the DSC include:
l Hill Decent Control (HDC).
l Electronic traction control (ETC).
l Anti-lock Braking System (ABS).
The DSC system for New Range Rover provides all of the following functions and features:
l Optimised traction under all driving conditions.
l Optimised directional control (Longitudinal Stability).
l Lateral stability (Correction for over steer/under steer).
l Corner Braking Control (CBC).
l Emergency Brake Assist (EBA).
l Electronic Brake Force Distribution (EBD).
For a detailed description of the ABS, HDC, and ETC systems, refer to the Brakes section
of the System Description and Operation Workshop Manual.
OPERATION
Power Distribution
Feed from the positive battery terminal (C0192) is supplied to the following on R wires:
l Fusible link 2 (C0632) – V8 vehicles only.
l Maxi fuse 63 (C0632).
l Fuse 13 (C0632).
l Fuse 53 (C0632).
l Fuse 55 (C0632).
l Fuse holder (C1875) – Td6 vehicles only.
Maxi fuse 63 (C0580) and fuse 55 (C0583) provide constant battery feeds to the ABS ECU
(C0506) on R and RB wires respectively. The ABS ECU is earthed on a pair of N wires. Fuse
13 (0586) provides a constant battery feed to the steering angle sensor (C0862) on an RG
wire.
Fuse 53 (C0583) provides a constant battery feed to the ignition switch (C0099 on Td6
vehicles, C0028 on V8 vehicles) on an R wire. When the ignition switch is turned to the
'auxiliary' position, current flows across the switch (C0099 on Td6 vehicles, C0028 on V8
vehicles) to fuse 37 of the passenger compartment fuse box (C0585) on a PB wire. Fuse 37
(C0587) provides an auxiliary ignition feed to the Dynamic Stability Control (DSC) switch
(C0700), located on the centre console, on a GBY wire.
