Where is my GEM Module located in my mercury 2005 Sable?

The GEM - genaric electronic module isn't part of the CJB ! It's a stand alone module .

It is located in the central junction box under the dash , F2.26 10Amp. fuse . along with interior lamps relay K333 .
Lamps, Courtesy The interior courtesy lamps are controlled by the generic electronic module (GEM) and are activated by the interior lamp relay. The interior lamp relay coil is grounded by the GEM when:

• a door is opened.
• illuminated entry is requested from remote anti-theft personality module.

The courtesy lamps will turn off if:

• ignition switch is turned to RUN.
• illuminated entry off request is received from remote anti-theft personality module or after 25-seconds.

• Corroded connectors.

1. If the inspection reveals an obvious concern that is readily serviced, correct the concern before continuing with Inspection and Verification.
   

1. If a concern remains after the inspection, connect Rotunda New Generation Star (NGS) tester 007-00500 or equivalent to the data link connector (DLC) located beneath the instrument panel to perform the Data Link Diagnostics Test. If the NGS responds with NO RESPONSE/NOT EQUIPPED for the Generic Electronic Module (GEM), GO to Pinpoint Test AD . If the Data Link Diagnostic test is passed for the Generic Electronic Module (GEM), retrieve continuous DTCs and execute self test diagnostics for the GEM.
   

1. If self test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics.
   

1. If DTCs are retrieved, go to the Generic Electronic Module (GEM) Diagnostic Trouble Code (DTC) Index to continue diagnostics.
   

1. If the Generic Electronic Module (GEM) cannot be accessed by the NGS tester, go to Pinpoint Test AD .
   

Rotunda Service Bay Diagnostic System (SBDS®) 001-00001 may also be used to diagnose this system.

     • front wiper and washer
     • warning chime
     • battery saver
     • illuminated entry and interior lighting
     • driver one-touch down power window (optional)
     • battery saver relay

     • safety belt warning indicator lamp
     The central security module controls the following features:
     
     • remote keyless entry
     • computer-operated lock system
     • trim switch unlock inhibit
     It's more then likely to have DTC'S diagnostic trouble codes stored in it's memory !

GEM stands for Generic Electronic Module. RCU stands for Rear Control Unit. Your in dash radio is just a faceplate. The audio unit is in the trunk.

It sounds like something is drawing power with the key off. It could be the GEM module but I doubt it. There is a draw somewhere. Connect battery and pull fuses one at a time to see if curent drain stops. You will need an ampmeter in series with the battery and the postive cable. Expensive. Get one from pick n pull salvage yard real cheap.

Check the following fuse junction panel fuses: fuse 23 (5A), fuse 20 (5A), and fuse 8 (5A).

could be the GEM module. Generic electronic module. expensive. get at salvage yard.

The power windows don't have a fuse, they are controlled by a part called a GEM, this stands for Generic electronic module, if the wipers work ok then the power windows have power available, the problem is if the GEM fails the power windows become inoperable, what is the exact nature of the problem you have, I am a Ford rained tech so know the system very well.

You probably have a door ajar switch that is bad. You can check the grounds coming from the switch that goes to the gem module and it should change from open to ground when you open and close the door. If you really think the gem module is bad or want to check it with your scematic. The gem module should be piggy backed behind the fuse panel inside your pick if you remove the fuse panel inside your truck you should be able to access the module but you have to remove the fuse panel completely from the truck to remove the gem module. Good luck with your problem.

you need to have your GEM module reconfigured after battery disconnect. It controls many functions. It may have also been damaged during battery change due to a voltage spike. Dealer can test it. Call a dealer service dept and describe symptoms and see what they say.

Module Controlled Functions NOTE: Prior to removal of the generic electronic module (GEM), it is necessary to upload module configuration information to the scan tool. This information needs to be downloaded into the new module once installed. For additional information, refer to Section 418-01 .
NOTE: Electronic modules are sensitive to electrical charges. If exposed to these charges, damages may result.
The generic electronic module (GEM) is the only multi-function module on this vehicle.
The GEM constantly monitors its subsystems for concerns. If a concern is found in one of the subsystems, the GEM will record the concern in the form of a diagnostic trouble code (DTC).
The ignition switch position is very important to the GEM functionality Erratic or unexpected GEM functions can often be traced to problems with these GEM inputs.
The GEM controls a variety of systems:

• instrument cluster warning indication and chimes
• interior courtesy lamp control
• automatic headlamp control
• daytime running lamps (DRL)
• wiper and washer (front only)
• heated rear window
• one-touch down power window
• delayed accessory
• power door locks (including SMART, autolocking and luggage compartment lid release)
• remote keyless entry
• perimeter anti-theft
