See the SYSTEM WIRING DIAGRAMS for schematic information.
DTC CHART - COMMUNICATIONS NETWORK
Note. DTC U1900 will set in a module that is reporting a communication fault from another module on the data bus. The module that reports the fault is not the problem module.
Note. Some modules on this vehicle 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.
Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of electrical damage. DTC CHART Electrical Battery junction box (BJB) fuse(s): MIDI 80A (no communication with power steering control module) 5 (10A) (no communication with PCM) 29 (15A) (no communication with PCM) Smart junction box (SJB) fuse(s): 5 (10A) (no communication with the SJB) 11 (10A) (no communication with 4X4 control module) 14 (10A) (no communication with front controls interface module (FCIM), front display interface module (FDIM), satellite digital audio receiver system (SDARS) module) 15 (10A) (no communication with HVAC module) 20 (15A) (no power to scan tool) 29 (5A) (no communication with instrument cluster) 31 (10A) (no communication with restraints control module (RCM)) 34 (5A) (no communication with ABS module) 35 (10A) (no communication with 4X4 control module, PSCM) 37 (10A) (no communication with HVAC module) 39 (20A) (no communication with audio control module (ACM)) 43 (10A) (no communication with the instrument cluster) 46 (7.5A) (no communication with occupant classification system module (OCSM)) Data link connector (DLC) Wiring, terminals or connectors
- 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. NOTE: The vehicle communication module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.
- If the cause is not visually evident, connect the scan tool to the 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. See «PINPOINT TEST 14: NO POWER TO THE SCAN TOOL»(ref-373079-S07026619992010100600000) .
- Carry out the network test. If the network test passes, retrieve and record the continuous memory DTCs and GO to the next step. If the network test fails, see «SYMPTOM TROUBLESHOOTING CHART»(ref-373079-S03295437462010100600000) to identify the module not communicating. NOTE: During the network test, the scan tool will first attempt to communicate with the PCM. After establishing communication with the PCM, the scan tool will then attempt to communicate with all other modules on the vehicle.
- If the DTCs retrieved are related to the concern, go to «DTC CHARTS»(ref-373079-S01409687142010100600000) . Follow the non-network DTC diagnostics (B-codes, C-codes, P-codes) prior to the network DTC diagnostics (U-codes). For all other DTCs, see «DIAGNOSTIC TROUBLE CODE (DTC) CHART - B, C AND U CODES»(ref-373079-S15371330202010100600000) .
- If no DTCs related to the concern are retrieved, see «SYMPTOM TROUBLESHOOTING CHART»(ref-373079-S03295437462010100600000) 09-01H-16.

DIAGNOSTIC PROCEDURE
Diagnostic Trouble Code (DTC) Chart
Note. Most powertrain (P-code) DTCs are diagnosed in TROUBLESHOOTING - 2.5L & 3.0L . If the P-code retrieved is not listed below, See DTC INDEX -- TRIBUTE HYBRID 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.
