| 1 | - | Driver's seat switch block with position memory |
| 2 | - | Seat control module |
The driver's power seat with memory is 6-way adjustable and includes the same controls as the front seat without memory. The seat has a seat control module located under the seat frame that allows up to 3 stored positions to be stored and recalled.
If memory-equipped outside rearview mirrors are installed, the seat control module also initiates movement of the outside mirrors by sending a command signal to the front door control modules when a seat position is recalled from memory. The front door control modules are used to store and recall the memory positions of the outside mirrors. For additional information, refer to: Rearview Mirrors (501-09 Rearview Mirrors, Description and Operation).
Seat control module
The seat control module is connected to the electrical wiring between the seat switch assembly and the seat adjustment motors. The module contains non-volatile memory (EEPROM).
The seat control module monitors the seat positions and stores the information provided by the Hall sensors in the seat runners. The Hall sensors are integrated into the seat adjustment motors. All stored seat position values and the current positions of the seat motors are stored in EEPROM memory.
If a power failure occurs, the motor positions stored in EEPROM are adopted as the current positions when power is restored. This allows the relative stored positions to be restored without recalibrating the seat control module.
The seat control module memory can be erased for a service update or read using Land Rover approved diagnostic equipment.
Up to three different seat positions can be stored in the seat control module. Seat positions are stored in memory by pressing the memory button (M) and then one of the 3 store buttons (1, 2, 3) for 5 seconds. The memory buttons are located on the switch block. The switch block memory buttons allow the driver to control the storage and recall of seat and exterior mirror adjustments. The switch block buttons are non-locking switches with self-return.
On vehicles equipped with a high-level instrument cluster, when the ignition is on, the seat position memory commands are displayed on the information centre display, and a single audible signal confirms that the new seat position has been memorised.
NOTE: The low level instrument cluster is not installed on vehicles equipped with the seat memory system.
For further information, refer to the chapter: Instrument cluster (413-01 Instrument cluster, Description and operation) / Information and message centre (413-08 Information and message centre, Description and operation).
The seat control module allows the driver to select the following functions:
- Recalling the seat position and exterior mirror settings from memory.
- Direct seat adjustment.
For further details on how the driver-selectable functions work, please refer to the Operating Principles section.
[Details can be found on the website: lrman.ru]
Seat operation is automatically monitored by the seat control module. The module detects motors that are not responding correctly to the operating request and also reduces power consumption during periods of inactivity.
The seat control module provides the following automatic control functions:
- Mechanism jam detection mode
- Standby mode
- Battery Monitoring Mode
For further details on how the automatic control functions work, please refer to the "Operating Principles" section.
Seat Control Module Calibration
When the seat control module is replaced during a service, the new module must be calibrated using Land Rover approved diagnostic equipment. The calibration procedure is necessary for the seat control module to restore the original seat position values.
