Principles Of Operation
Note. Upon installation of a new generic electronic module (GEM), the module must be reconfigured. Refer to MODULE CONFIGURATION article prior to GEM removal.
The GEM receives inputs and delivers outputs to a majority of the electronically controlled features of the vehicle. The GEM constantly monitors the systems under its control and reports a concern in the form of a diagnostic trouble code (DTC). The DTC can be retrieved with a diagnostic tool through the ISO 9141 communication network. The GEM controls the following features
- Front Wiper And Washer
- Warning Chime
- Battery Saver
- Illuminated Entry And Interior Lighting
- Driver One-Touch Down Power Window (Optional)
- Door Ajar Warning Indicator Lamp
- Safety Belt Warning Indicator Lamp
Inspection & Verification
- Verify the customer concern by operating the system.
- Visually inspect for obvious signs of electrical damage: Electrical Visual Inspection Central Junction Box (CJB) fuse: 10 (7.5A) 20 (7.5A) 25 (7.5A) 28 (7.5A) Wiring Harness Connector(s) Circuitry
- If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle: Check that the program card is correctly installed. Check the connections to the vehicle. Check the ignition switch position.
- If diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
- Carry out the DATA LINK DIAGNOSTICS test. If the diagnostic tool responds with: CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to «MODULE COMMUNICATIONS NETWORK»(/ford/explorer-sport-trac/i-2000-2005/remont/communication-devices/#module-communications-network) article. NO RESPONSE/NOT EQUIP for GEM, go to «PINPOINT TEST A: NO COMMUNICATION WITH THE GENERIC ELECTRONIC MODULE (GEM)»(/ford/explorer-sport-trac/i-2000-2005/remont/communication-devices/#multifunction-electronic-control-modules) . SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the GEM.
- If the DTCs retrieved are related to the concern, go to the «DIAGNOSTIC TROUBLE CODE CHART»(/ford/explorer-sport-trac/i-2000-2005/remont/communication-devices/#multifunction-electronic-control-modules__diagnostic-trouble-code-chart) to continue diagnostics.
- If no DTCs related to the concern are retrieved, refer to the appropriate system article to continue diagnostics.

The central security module controls the following features
- Remote Keyless Entry System
- Computer-Operated Lock System
- Verify the customer concern by operating the system.
- Visually inspect for obvious signs of electrical damage: Electrical Visual Inspection Central Junction Box (CJB) fuse: 18 (25A) 11 (7.5A) Wiring Harness Connector(s) Circuitry
- If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle: Check that the program card is correctly installed. Check the connections to the vehicle. Check the ignition switch position.
- If diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
- Carry out the DATA LINK DIAGNOSTICS test. If the diagnostic tool responds with: CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to «MODULE COMMUNICATIONS NETWORK»(/ford/explorer-sport-trac/i-2000-2005/remont/communication-devices/#module-communications-network) article. NO RESPONSE/NOT EQUIP for central security module, go to «PINPOINT TEST B: NO COMMUNICATION WITH THE CENTRAL SECURITY MODULE»(/ford/explorer-sport-trac/i-2000-2005/remont/communication-devices/#multifunction-electronic-control-modules) . SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the central security module.
- If the DTCs retrieved are related to the concern, go to the «DIAGNOSTIC TROUBLE CODE CHART»(/ford/explorer-sport-trac/i-2000-2005/remont/communication-devices/#multifunction-electronic-control-modules__diagnostic-trouble-code-chart) to continue diagnostics.
- If no DTCs related to the concern are retrieved, refer to the appropriate system article to continue diagnostics.
