Principles of Operation
The Generic Electronic Module (GEM) controls various systems (such as turn lamps, interior lighting, power door locks, wipers and the battery saver feature) by monitoring inputs from switches, sensors and messages sent from other modules on the Medium Speed Controller Area Network (MS-CAN). Based on the inputs received, the SJB activates outputs. For example, the SJB monitors the door ajar switches. Based on this input, the SJB may provide voltage to the interior lamps.
Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Central Junction Box (CJB) fuse 179 (7.5A) Generic Electronic Module (GEM) logic
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
- If the scan tool does not communicate with the VCM check the VCM connection to the vehicle. check the scan tool connection to the VCM . refer to «MODULE COMMUNICATIONS NETWORK»(/ford/transit-connect/i-2009-2013/remont/communication-devices/#module-communications-network) article, No Power To The Scan Tool, to diagnose no power to the scan tool.
- If the scan tool does not communicate with the vehicle: verify the ignition is ON. The air bag warning indicator prove-out confirms ignition ON (other indicators may not prove ignition ON). If the ignition does not turn on, refer to «STEERING COLUMN SWITCHES»(/ford/transit-connect/i-2009-2013/remont/steering-column-switches/#steering-column-switches) article to diagnose no power in RUN. verify the scan tool operation with a known good vehicle. refer to «MODULE COMMUNICATIONS NETWORK»(/ford/transit-connect/i-2009-2013/remont/communication-devices/#module-communications-network) article, The PCM Does Not Respond To The Scan Tool, to diagnose no response from the PCM.
- Carry out the network test. If the scan tool responds with no communication for one or more modules, refer to «MODULE COMMUNICATIONS NETWORK»(/ford/transit-connect/i-2009-2013/remont/communication-devices/#module-communications-network) article. If the network test passes, retrieve and record the continuous memory DTCs.
- Clear the continuous DTCs and carry out the self-test diagnostics for the GEM .
- If the DTCs retrieved are related to the concern, Go to «DTC CHARTS»(/ford/transit-connect/i-2009-2013/remont/communication-devices/#multifunction-electronic-module) .
- If no DTCs related to the concern are retrieved, Go to «SYMPTOM CHART»(/ford/transit-connect/i-2009-2013/remont/communication-devices/#multifunction-electronic-module__symptom-chart) .
