  4. If the cause is not visually evident, connect the diagnostic tool to the data link connector 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 (if using NGS).
    • Check the connections to the vehicle.
    • Check the ignition switch position.
  5. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.
  6. Carry out the data link diagnostics test. If the diagnostic tool responds with:
    • SCP+, SCP-, UBP or CAN or ISO circuits fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
    • No response/not equipped for powertrain control module (PCM). Refer to MODULE COMMUNICATIONS NETWORK to diagnose module communication problems.
    • No response/not equipped for 4x4 module, GO to PINPOINT TEST A .
    • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the self-test diagnostics for the 4x4 module.
  7. If the DTCs retrieved are related to the concern, go to the 4X4 MODULE (PCM) DTC INDEX  to continue diagnostics.
  8. If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART .
