    • 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 (PCM), GO to PINPOINT TEST J .
    • 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 (PCM).
  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 .
