in the lower left side of the frame and drives both
sides of the squab. The position potentiometer is
mounted on the long drive shaft on the RH side.
Lumbar support comprises a flexible steel lumbar
plate, motor, drive cable and return spring. The
top of the plate has vertical slots, fitted to a cross
bar, which allows the plate to be pulled down and
deformed by the drive cable to provide increased
lumbar support. If powered lumbar support is not
fitted, the lumbar plate is used without the drive
system.
When seat heaters are fitted each front seat has a
driver or passenger seat heater control module
fitted (DSHCM/PSHCM).
Seat Covers
The cushion and squab cover are made of dual
density foam and have optional heater pad inserts.
The cushion and cushion pan have an anti-
submarining profile for increased safety.

Introduction
The automatic and manual transmission units are
described in the ÔS-TYPE Sports Sedan Powertrain
IntroductionÕ Technical Guide.
J-Gate
The J-gate assembly is mounted on the
transmission tunnel by four bolts and has a
similar operating mechanism to the XJ/XK Series
vehicles. The selector gate positions are, P-R-N-D
on one side of the ÔJÕ and manual gear positions
4-3-2 on the other side. Movement of the gear
selector lever up and down these positions is
transmitted mechanically to a cable assembly
which then rotates the digital range switch on the
side of the automatic transmission housing (see
ÔS-TYPE Powertrain IntroductionÕ Technical
Guide). Movement across the gate between D and
4 operates an electrical switch (without cable
movement).
In the P position with the ignition off, the gear
selector lever is locked by a solenoid plunger
which inhibits a lock plate fixed to the selector
mechanism. When the ignition is switched on,pressing the brake pedal energises the solenoid
and releases the lock plate, allowing the selector
lever to be moved from the P position.
For NAS markets only, the J-gate slider actuator is
linked to the ignition switch barrel to provide a
mechanical interlock. The interlock lever and
cable are driven by the J-gate slider to operate a
locking plunger in the ignition barrel. If the gear
selector lever is in any position other than P, the
ignition key cannot be removed. Note when
servicing, that the interlock cable adjustment is
critical and the JTIS service instructions must be
followed. Where the interlock function is not
fitted, the interlock lever is retained without the
operating cable.

STEERING COLUMN LOCK MODULE
Steering Column Lock (where fitted)
Lock Operation
The steering column lock module (SCLM) and
ignition key switch are separate assemblies and
activation of the lock is remotely controlled by the
instrument pack, GECM and RECM. The column is
unlocked on insertion of the ignition key and is
locked when the key is withdrawn.
The SCLM is mounted on top of the lower casting,
on the upper column assembly, by two shear
bolts. A locking bolt projects down from the SCLM
through a hole in the lower casting to engage into
a splined collar on the steering column. The SCLM
is an integrated non-serviceable assembly, housinga motor and worm drive for the locking bolt and
also an electronic printed circuit board. When
activated, the locking bolt is driven positively in
both the lock (down) and unlock (up) directions
and has a spring to help locate it into the trough
of the splined collar. When disengaging, the
locking bolt is driven upwards until it operates a
microswitch (within the SCLM) which causes the
motor to stop and also signals via the SCP bus that
the steering lock is off. To engage the lock, the
motor is energised for 350ms to lower the bolt.
System Control
The lock motor is powered by a switched 12V line
from the RECM and switched ground line from the
GECM, with both supplies being applied only
during lock operation. Initiation of motor drive
and direction and power supply switching is
controlled by the instrument pack via the SCP bus
when ignition key insertion or withdrawal is
detected. Identification is checked between the
SCLM and the other modules and the system will
not operate if, for example, a module has been
replaced and not re-programmed. System
diagnostics include defective modules and
incorrect module identification and also certain
SCLM faults, ie unconfimed lock or unlock
conditions and failed microswitch.
Steering Column Shrouds
The upper part of the column assembly is
enclosed by two plastic shrouds, upper and lower.
The steering column adjust switch, controlling tilt
and reach for the electrically powered steering
column assembly, is mounted on the side of the
lower shroud.

74The SCP communication network will remain
operational even with severing of one of the bus
wires. Communications will also continue if one
of the bus wires is shorted to ground or battery
positive voltage (B+), or if some , but not all,
termination resistors are lost.
Unlike the SCP communication network, the
ISO 9141 communication network will not
function if the wire is shorted to ground or battery
positive voltage (B+). Also, if one of the modules
on the ISO 9141 network loses power or shorts
internally, communication to that module will fail.
Control Modules
The vehicle control module functions are
described briefly below (for further information
refer to the relevant sections throughout the
Guide).
Anti Lock Brake/Traction Control and
Dynamic Stability Control, Control Modules
The anti-lock brake control module is connected
to the SCP communication network. The module
comes in two forms. The first type is the standard
equipped anti-lock brake system (ABS) with
traction control (TC). It controls the brake
pressure to the four wheels to keep the vehicle
under control while braking.
The second type of ABS is optional and is called
dynamic stability control (DSC). This control
module adds yaw sensors to the package to help
in sensing a loss of vehicle control.
Audio Control Unit
The audio control unit is connected to the SCP
communication network and also to the audio
control protocol (ACP) communication network.
The audio control unit communicates with the
compact disc and the cellular phone transceiver.
Driver Door Control Module (DDCM)
DDCM is connected to the SCP communication
network. The module controls many functions
including power windows, driver mirror, power
locks, and keyless remote entry.Driver Seat Control Module (DSCM)
The DSCM is connected to the SCP
communication network. The DSCM is located
under the driver seat and controls the seat
positions. The module also communicates with the
DDCM to control the driver seat memory
functions.
