Driver's seat position

Principles of Operation
The driver seat module (DSM) is on the controller area network (CAN) communication network. To support several vehicle subsystems, the module permits intermodule and diagnostic tool communications.
The DSM controls the memory driver seat and the passenger memory power exterior mirror. This passenger memory power exterior mirror feature allows the driver to program personalized mirror positions. Once the driver stores a mirror position, the driver can recall the setting by pressing the corresponding memory switch or by using a programmed remote keyless entry (RKE) transmitter. For additional information, refer to Section 501-10 .

How to Diagnose Controller Area Network CAN

Driver Seat Module - Memory Seat
The power driver seat, power outside rear view mirrors and power adjustable pedals are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option. The DSM is located on the driver seat track.
This system allows automatic positioning of the driver seat to 2 programmable positions.

• A power driver seat position can be stored at any time. The driver must move the seat to the desired position using the driver seat switch assembly. The driver must then depress the memory SET switch which activates the memory SET switch light emitting diode (LED). Within 5 seconds (before the LED goes out), the driver must select a memory position. Memory 1 is selected by depressing memory switch 1. Memory 2 is selected by depressing memory switch 2.
• If no memory switch input is received within the 5-second time limit, the operation is aborted and the memory seat position switch (set switch) LED is turned OFF. This also occurs if one of the following inputs is received during the 5-second programming limit:
  • Driver seat control switch
  • Memory seat position switch (set switch)
  • Power adjustable pedal switch

A programmed seat position can only be recalled when the transmission selector is in PARK or NEUTRAL with the ignition switch in the RUN position. A position may be programmed at any time.

Easy Entry/Easy Exit
The driver power seat easy entry/easy exit feature can be enabled/disabled. Refer to Section 418-01 or the owner's literature.

This may need to be done with a scan tool

See pg. 3-31 in owners manual. Start car in park. Adjust seat, telescoping wheel, and side view mirrors. Pust Mem button and then within 5 sec. push either 1 or 2. That button should light to show memory stored.
From the 2012 Guide (See link)
l"AUTOMATIC DRIVE POSITIONER (if so equipped) Two positions for the driver's seat, steering column and outside mirrors can be stored in the automatic drive positioner memory. Follow these procedures to set the memory positions: • Confirm the shift lever is in the P (PARK) position. • Push the ignition switch to the ON position. • Adjust the driver's seat, steering column and outside mirrors to the desired positions using the adjusting switches for each feature. • Push the SET switch and within 5 seconds, push the memory switch (1 or 2) for at least 1 second. • The indicator light on the memory switch you select will illuminate for approximately 5 seconds. • The driver's seat, steering column and outside mirror positions are now set to your preference. These memorized positions can also be linked to your NISSAN Intelligent Key®. For more information, refer to the "Pre-driving checks and adjustments (section 3)" of your Owner's Manual." https://owners.nissanusa.com/content/techpub/ManualsAndGuides/Murano/2012/2012-Murano-quick-reference-guide.pdf
For added info see whole owners manual.

is there a preset option on this model if so you will have to set mirrors where you want them as it may be reseting to a previous setting , how long has this been happening ?

The ignition key won't turn likely because the shifter linkage that locks the key in OFF is worn or loose. Move the shifter linkage hard to the Park position and the key will turn. Have the linkage adjusted and the worn parts replaced

BCM has nothing to do with this function , MMM - memory mirror module !
Memory Mirror System Operation
The MMM is capable of storing mirror position for 2 different drivers. Mirror position is determined by both horizontal and vertical position sensors in each of the power mirrors. The MMM supplies a reference voltage and a low reference to these sensors and determines mirror position through the horizontal and vertical position signal circuits.
The MMM receives power through the battery supply voltage circuit and the MIR/LOCK fuse and a constant ground source. Any time that battery voltage is disconnected and then connected from the MMM, the MMM will enter the mirror relearn mode. The mirror relearn mode can also be commanded using a scan tool. Refer to Memory Mirror Module Learn for further information.The memory switch receives power through the battery supply voltage circuit and the MIR/LOCK fuse. The MMM upon receipt of a memory switch signal input, a class 2 message from the SIC or a class 2 message from the PCM indicating that the transmission is in park, will then supply battery voltage and ground to the appropriate power mirror motors through the mirror motor control circuits to move the mirrors to the predetermined positions.

DTC B1586, B1596, B1616, or B1626
The mirror horizontal and vertical position sensors are potentiometers. The Memory Mirror Module (MMM) provides these sensors with a 5 volt reference circuit and a low reference circuit. The MMM monitors the horizontal and vertical position sensor signal circuits which change values based on mirror position. These voltage values are used to determine mirror position and can be set into memory. When the MMM receives a memory recall request, the MMM will control the power mirror to the memory position based on the horizontal and vertical position sensor signal values.

Install a scan tool.
Turn ON the ignition, with the engine OFF.
With the scan tool, observe the mirror horizontal and vertical position parameters in the Memory Mirror Module (MMM) data list.
Operate both the left and right mirrors through the full range of movements.
Does the scan tool indicate that the left and right mirror horizontal and vertical position parameters are within the specified range?

Memory Seat System Components
The memory seat system consists of the following components:
• Power seat switch assembly
• Memory recall switch assembly
• Horizontal adjuster motor
• Front vertical adjuster motor
• Rear vertical adjuster motor
• Recline adjuster motor
• Memory seat module
• Memory mirror module
• SEAT 25A circuit breaker
• MIR/LOCK 3A fuse

Your best bet , take it to a qualified repair shop !

I would safely assume your right mirror may be inoperable period then by your statement you are leaving the switch for the mirrors in the middle during switching correct and during adjustment are switching to R/L mirror on the switch? Mirrors are on the same circuit so both should be operable. Have the mirror checked for operation before heading any further. I Think you will find during this its unplugged from its source of power or inoperable period and needs replaced. Remember to rate my solution and leave testimonial PS please purchase you a Owners Manual for your car you will thank me later.

Hi the steering lock could be causing you the problem try turning the steering wheel hard left whilst turning the key and do the same hard right.

it may be hard to turn but you should find once you have moved it slightly it will unlock allowing you to turn the key so dont adjust the steering wheel turn it to the right as if your trying to turn to the right and if this dont let the key turn turn the wheel to the left it only needs to move slightly to allow the steering lock to free the key,

doing the above should solve you problem

give me a shout back if you have any further problems ok

does this have automatic seat positioning when you open the door or hit the unlock button on your key fob?

here's how it works:

Seats — Programmable
The memory seat system allows automatic positioning of the driver seat to two programmable positions using the message center, the key fob or the keypad on the door.
Seats — Driver Seat Module
The Driver Seat Module (DSM) is located under the driver's seat and is attached to the seat frame. The DSM will:

• control the movements of the driver's seat and power exterior rearview mirrors
• store and recall seat and mirror positions of two personalized settings
• receive all power seat and mirror control inputs from the Driver's Door Module (DDM) through the J1850 communication network
• move the exterior rearview mirrors downward when the transmission is shifted into reverse, if enabled.

Seats — Driver Door Module
The driver's seat regulator control switch is connected to the Driver Door Module (DDM). The DDM receives the driver's seat regulator control switch input and communicates the direction of movement over the J1850 communication network.

Also, the dealer can run a scan on your seat modules with his tester and tell you what the codes are. They should only charge an hour to do this. Then you can decide what to do. Call your dealer and ask how much to run the scan test.

When they did the alignment it's possible that they used a tool that locks the steering wheel straight while it's on the alignment rack.If they put too much pressure on the wheel when they used the steering wheel seat lock tool it may have stressed you tilt lock mech causing it not to lock where you want it.Hope this helps

this might be a faulty preset sensor on the seat. which explains why the sterring wheel and mirrors work on preset but the seat doesn't
