TECHNICAL INFORMATION

The 61359134661 / 9134661 module forms part of the electrically adjustable driver’s seat system.

Its functions can include management of:

• Electric fore/aft seat adjustment

• Seat height adjustment

• Seat backrest adjustment

• Seat angle / tilt adjustment

• Memory position functions

• Communication between seat switches and adjustment motors

• Integration with the vehicle’s comfort electronics

Exact functions depend on the equipment installed in the vehicle.

ELECTRIC MEMORY SEAT SYSTEM

This module is associated with BMW vehicles equipped with S459A – Electric Seat Adjustment with Memory.

The memory system allows selected driver’s seat positions to be stored and recalled rather than requiring the seat to be manually readjusted each time.

The control module processes commands from the seat adjustment controls and operates the appropriate seat adjustment motors.

COMMON SYMPTOMS OF A FAULTY MODULE

Replacement may be required if you experience:

• Electric driver’s seat not operating

• Memory seat function not working

• Individual seat adjustments not responding

• Intermittent electric seat operation

• Seat motors working incorrectly despite good wiring

• Communication fault relating to the seat module

• Water or moisture damage to the original module

• Physical or electrical damage following seat removal

• Replacement required during electric-seat repair

IMPORTANT DIAGNOSTIC INFORMATION

Before replacing the module, check:

• Seat fuses and power supply

• Seat wiring loom

• Electrical connectors underneath the seat

• Seat adjustment switches

• Electric adjustment motors

• Ground connections

• Wiring for damage caused by seat movement

• Diagnostic fault codes where available

A non-working electric seat does not automatically mean the control module has failed.

Damaged wiring underneath electrically adjustable seats is another possible cause of intermittent or completely inoperative adjustment.

PART NUMBER INFORMATION

BMW OE Number: 61359134661

Short / Printed Number: 9134661

BMW used several related seat control modules, including numbers within the 913466x / 914826x families.

These modules should not automatically be considered interchangeable solely because they look identical.

The replacement module should be selected according to the original part number, vehicle production date and seat equipment.

INSTALLATION

The module is installed as part of the front driver’s electric seat assembly.

Depending on vehicle configuration, seat removal or movement may be necessary to access the module and electrical connectors.

IMPORTANT: BMW seats contain connections associated with the vehicle’s SRS / airbag and seat-belt restraint systems.

Correct battery-disconnection and BMW repair procedures should be followed before disconnecting seat electrical components.

Professional installation is recommended.

PROGRAMMING / CODING

Coding / programming may be required depending on the vehicle and replacement situation.

A like-for-like replacement with the same OE number may operate without extensive configuration in some applications; however, used BMW electronic modules can retain vehicle-specific configuration.

For best results, the replacement should be checked using appropriate BMW diagnostic equipment after installation.

Retrofitting electric or memory seats into a vehicle that was not originally equipped with them can require additional wiring, modules and vehicle coding.

IMPORTANT COMPATIBILITY NOTE

Before purchasing, please compare:

• Vehicle chassis – E87 / E90 / E91 / E92

• Vehicle production date

• Driver/passenger position

• Electric seat specification

• Memory seat option S459A

• Module electrical connectors

• Number and position of connector pins

• Existing module number

• Listing photographs

Matching the OE number and electrical configuration is strongly recommended.

Do not purchase solely based on the vehicle model or engine size, as BMW fitted different modules according to the vehicle’s factory seat equipment.
