Inspection and Verification

  1. Verify the customer concern.
  2. Visually inspect for obvious signs of electrical damage.
    • If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
    VISUAL INSPECTION CHART

    Electrical
    • BJB fuse(s):
      • MIDI 80A (no communication with power steering control module PS CM)
      • 5 (10A) (no communication with PCM, TCM [Hybrid only])
      • 6 (5A) (no communication with ABS module [Hybrid only])
      • 8 (10A) (no communication with BCM [Hybrid only])
      • 9 (50A) (no communication with ABS module)
      • 18 (20A) (no communication with ABS module [Hybrid only])
      • 23 (5A) (no communication with BCM [Hybrid only])
      • 24 (10A) (no communication with TCM [Hybrid only])
      • 26 (20A) (no communication with BCM [Hybrid only])
      • 27 (20A) (no communication with ABS module [Hybrid only])
      • 29 (15A) (no communication with PCM)
    • SJB fuse(s):
      • 3 (15A) (no communication with APIM)
      • 5 (10A) (no communication with the SJB)
      • 11 (10A) (no communication with 4X4 control module)
      • 14 (10A) (no communication with FCIM, FDIM, SDARS module)
      • 15 (10A) (no communication with HVAC module)
      • 20 (15A) (no power to scan tool)
      • 29 (5A) (no communication with IC
      • 31 (10A) (no communication with RCM)
      • 34 (5A) (no communication with ABS module [except Hybrid])
      • 35 (10A) (no communication with PAM, 4X4 control module, PSCM)
      • 37 (10A) (no communication with HVAC module)
      • 39 (20A) (no communication with ACM)
      • 43 (10A) (no communication with the IC)
      • 46 (7.5A) (no communication with the OCSM)
    • DLC
    • Wiring, terminals or connectors
  3. Connect the scan tool to the Data Link Connector (DLC).
      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 Integrated Diagnostic System (IDS) does not communicate with the VCM:
      • Check the VCM connection to the vehicle.
      • Check the scan tool connection to the VCM.
      • GO to PINPOINT TEST V , to diagnose No Power To The Scan Tool.
  4. Establish a scan tool session.
      NOTE: 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 an IDS session cannot be established wit the vehicle, (IDS may state "No communication can be established with the PCM"):
      • Choose "NO" when the scan tool prompts whether or not to retry communication.
      • Enter either a PCM part number, tear tag or calibration number to identify the vehicle and start a session.
  5. Carry out the network test.
    • If the network test passes, retrieve and record the continuous memory DTCs and proceed to Step 6.
    • If the network test fails, GO to SYMPTOM CHART  to diagnose the failed communication network.
    • If a module fails to communication during the network test, GO to SYMPTOM CHART .
  6. Retrieve and review the DTCs.
    • If the DTCs retrieved are related to the concern, go to DTC CHARTS . Follow the non-network DTC diagnostics (B-codes, C-codes, P-codes) prior to the network DTC diagnostics (U-codes). For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in MULTIFUNCTION ELECTRONIC MODULES .
    • If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART .
