Multifunction Electronic Modules: Diagnosis — Ford Expedition III (2006-2014)

Diagnostic Trouble Code (DTC) Chart

Note. Most powertrain (P-code) DTCs are diagnosed in the INTRODUCTION - GASOLINE MODELS . If the P-code retrieved is not listed below, refer to the INTRODUCTION - GASOLINE MODELS to continue diagnostics.

Note. The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

Note. Some of these modules utilize a 5-character DTC followed by a 2-character failure-type code. The failure-type code provides information about specific fault conditions such as opens, or shorts to ground. Continuous memory DTCs have an additional 2-character DTC status code suffix to assist in determining DTC history.

DTC CHART

Inspection and Verification

Verify the customer concern.
Visually inspect for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Battery Junction Box (BJB) fuse 56 (30A) Smart Junction Box (SJB) fusible link D (10 Ga) SJB fuse(s): 5 (10A) 6 (20A) 7 (10A) 8 (10A) 9 (15A) 10 (15A)
If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
NOTE: Make sure to use the latest scan tool software release. If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM . 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»(ref-364058) , 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 key is in the ON position. Verify the scan tool operation with a known good vehicle. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-364058) 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»(ref-364058) . 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 SJB .
If the DTCs retrieved are related to the concern, go to «DTC CHARTS»(ref-364059-S22903000992010062700000) .
If no DTCs related to the concern are retrieved, GO to «SYMPTOM CHART»(ref-364059-S11596008462010062700000) .

SYMPTOM CHART

PINPOINT TEST A: DTCs B106E, B106F

Note. If DTC B106F is present and a new SJB is to be installed, the fault condition must be corrected first. Failure to correct the fault condition first may cause damage to the new SJB , resulting in a repeat repair.

A1 REVIEW THE DTCs Review the DTCs from the SJB self-test. Are only DTCs B106E and B106F present? Yes: INSTALL a new SJB . REFER to «SMART JUNCTION BOX (SJB)»(ref-364059-S20508366472010062700000) . TEST the system for normal operation. No: CORRECT any DTCs present other than DTCs B106E and B106F. REFER to the «DTC CHARTS»(ref-364059-S22903000992010062700000) . After the repair, GO to A2 .
A2 CARRY OUT THE SJB SELF-TEST Carry out the SJB self-test. Is DTC B106F present? Yes: INSTALL a new SJB . REFER to «SMART JUNCTION BOX (SJB)»(ref-364059-S20508366472010062700000) . TEST the system for normal operation. No: The system is operating correctly at this time. The concern was caused by a fault in one of the output circuits.

Pinpoint Test B: DTC B1317

Refer to SYSTEM WIRING DIAGRAMS (Expedition), SYSTEM WIRING DIAGRAMS (Expedition EL), SYSTEM WIRING DIAGRAMS (Navigator) or SYSTEM WIRING DIAGRAMS (Navigator L) for schematic and connector information.

Note. DTC B1317 may be stored in the module memory due to previous battery charging or vehicle jump starting events.

B1 CHECK FOR DTC B1317, B1676 OR P0563 SET IN OTHER MODULES Ignition ON. Enter the following diagnostic mode on the scan tool: (All Modules) Self-Test. Retrieve the continuous memory DTCs from all modules. Is DTC B1317, B1676 or P0563 (PCM) set in more than one module? Yes: REFER to «CHARGING SYSTEM»(ref-364045) to diagnose an overcharging condition. No: GO to B2 .
