memory positions to be stored and 'set' button with integral LED (light emitting diode). The seat, door mirror and steering
column motors have position sensors which provide feedback to driver's seat module.
Once the driver's seat, steering column and exterior mirrors have been adjusted, the vehicle is able to memorize these
settings for future use by using the following procedure:
Push the memory 'SET' button, the LED in the switch will illuminate Press the memory button 1 or 2 to memorize the current settings. The LED will extinguish, and a chime will sound to confirm that the settings have been memorized. If the ignition is on, power mode 6, the message center will display a
confirmation message.
The positions can be recalled by pressing the applicable button 1 or 2.
Stall Detection
Seat, steering column and mirror motors are deemed to have stalled if there is no change in the inputs that are received from
the corresponding feedback sensors for 200 ms (seat).
If a stall condition is detected then the drive to that motor is cancelled for the remainder of that memory operation (memory
recall) or until the switch is re-selected (manual movement).
If the motor movement has stopped due to loss of sensor feedback, either stall or sensor failure, then that motor may be
activated again, to move past the stall position, by re-selecting the appropriate switch and pressing for longer than 2 seconds.
This allows control of the motor to be maintained if sensor feedback is lost.
Upon re-selection of movement, if sensor pulses are detected then the motor will continue to be driven until the switch is
released or another stall condition is detected. If sensor feedback is not detected then the motor is only driven for 0.5 second
and then stops until the switch is released and then pressed again, when a further 0.5 second of activation is permitted, and
so on, this is known as inch mode.
For all seat motor manual movements, whenever a motor is driven and a stall occurs, the memory control module records the
position at which the stall occurred. If movement occurs beyond a stall position, then that position is erased from the control
modules memory. This will always allow movement past a previously recorded stall position once movement has been
registered beyond that position. This is the case for both manual and memory movement.
Initialization
When a replacement driver's seat module is fitted, it should be calibrated a Jaguar approved diagnostic system so that the
module can learn the seats absolute position.
Battery Monitor
If the battery voltage drops below 10.5 Volts, then the driver's seat module ignores all requests for a memory recall until the
battery voltage has reached 11.5 Volts. This will conserve as much power in the vehicle battery as possible to enable engine
cranking.
REAR SEATS - DESCRIPTION
The rear seat features a single piece cushion and a 60/40 split squab. Two latches are secured to the rear bulkhead by a pair
of M8 bolts to retain the seat squabs in the upright position. The latches can be released to fold down the individual cushions
by pulling a cable release located below the rear window parcel shelf in the luggage compartment.
ISOFIX fastening points are attached to the vehicle floor to provide secure fastening for compatible child seats.
A centrally mounted center arm rest can be folded down from the 60% squab. The arm rest contains two drinks holders.
