Electronic shifter module - 2005 Jeep Grand Cherokee

no country stated,
the WG jeep, in Europe?
ours is WJ. or USA?
one car underhood.
other next to shifter box.
next time post country. be like the 9th ever.
and be a win/win. no more easter egg hunts.
on our USA gas engines, its in the PCM now.
but not most diesels it's an addon.

That code is a shifter control module. Since it sounds like you already purchased a new one, try resetting the code. Some cheap scanners cannot reset a "U" code. Is it shifting properly?

The electronic shifter is located on the transmission itself. It is called a shift control module. If you plan to replace the shift control module, it is at least $200 and you have to match EXACTLY for that make, model, year and transmission.

the A/T ?
many AT have a vacuum modulator that can fail and the engine sucks ATF. (not on most 2008 with electronic shifter brain)
or the ATF is going into the RADIATOR cooler . bingo?

i bet you just found it. old post.....

google cleaning jeep grand cherokee shifter module its the same thing
or google grand cherokee or commander forums find a few and post this and all future questions there
if you are speaking of all the shift positions being surounded by brackets like [r] [n] [d] [l] than thats likely the problem the part can be cleaned its located beneath the shifter bezel or replace it the part is about 450 to 500 bucks but try the foorums i know ive seen a writeup with pictures there

check the brake lights and make sure they work if the boo (brake on off signal dosn't get to the GEM (generic electronic module) then it dosent send the signal to unlock the shifter

Check all main power feeds to all fuse centers (boxes) ! Do you know what a electrical distribution diagram is ? How to use a DVOM - digital volt ohm meter to test electrical circuits ?
Has no power, replaced shifter assembly ???? No power where ??? And why would you replace shifter assembly ???? What happens when you turn the key to on ? not start ,just on ? Insturment cluster lights up ?
Is the battery good ? Connections an cables ? Your going to need to check power at the battery ,fuse boxes etc.... Confirm there is B+ voltage somewhere !
Your best bet , take it to a qualified repair shop . You have no idea of the complexity of this vehicle ! Everything is contolled by computer ! The ignition switch is a input to the BCM - body control module , by these inputs the BCM will control the vehicle .
The body control module (BCM) has a bussed electrical center integrated into the housing. Body control relays and fuses are installed directly on the BCM, which simplifies wiring and junction blocks on the vehicle. The body control system consists of the BCM and its associated controls. Battery positive voltage is provided to the BCM from IBCM BATT 1 fuse and the IBCM BATT 2 fuse in the underhood fuse block. The module grounds are wired to ground G201, G203 and G305. The BCM is wired to the GMLAN High speed serial data buss, and the GMLAN Low speed serial data buss, as well as discrete input and output terminals to control the functions of the vehicle's body .
Serial Data Gateway
The body control module (BCM) in this vehicle functions as a translator between the High and Low speed GMLAN busses. The 2 communication protocols use the BCM to translate communicated serial data messages between the control modules over the 2 serial data busses.
Power Mode Master
This vehicles body control module (BCM) functions as the power mode master (PMM). Refer to Power Mode Description and Operation for a complete description of power mode functions.
Power to many of this vehicle's circuits are controlled by the module that is designated the power mode master (PMM). This vehicle's PMM is the body control module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.
Serial Data Power Mode Master
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle, the PMM is the body control module (BCM). The PMM receives 3 discrete ignition switch signals to differentiate which power mode will be sent over the Serial Data circuits. The 3-wire Ignition Switch table below illustrates the state of these inputs in correspondence to the ignition switch position:

Relay Controlled Power Mode
The body control module (BCM) uses the discrete ignition switch inputs Off/Run/Crank, Accessory, and ignition 1, to distinguish the correct power mode. The ignition 1 circuit is also routed to the Run/Crank relay for relay controlled power feeds during the appropriate power mode. The BCM, after determining the desired power mode, will activate the appropriate relays for that power mode.
Run/Crank Relay
The run/crank relay control circuit is connected to a constant ground and is switched by the ignition 1 circuit or the body control module (BCM). The BCM, will in lieu of the ignition switch position, activate the Run/Crank relay during a remote start event. The Run/Crank relay supplies a power signal to the following circuits, when the a Run or Crank power mode is selected:
• Automatic transmission shift indicator
• Automatic transmission (A/T)
• Switched power feeds to the BCM
• Electronic brake control module (EBCM)
• Electronic ignition module (spark control)
• Electronic power steering module (EPS)
• Fuel injectors
• Powertrain control module (PCM)
• Park neutral position (PNP) switch

Do yourself a favor an take it to a qualified repair shop !

Sounds like your cable has broken or come off on the side of the transmission this is your problem it snaps off and on under the vehicle. and if the linkage is intact and moves it is the electronic module on the side of the transmission behind the shift cable.Remember to rate my solution and give testimonial this is how i earn my achievements here on FixYa Thanks in advance if you need further help just ask

it sounds like your shift linkage has come loose, or broken. this is the component that links your shifter to your transmission. in some cases they are an electronic module, and sometimes a its a mechanical lever style mechanism. that is where i suggest to start looking. i hope this helps

hi
my nissan titan 2007 batery died then i put new batery in but still cant trun on ????
