- CKT930, CKT914, CKT915 or CKT70; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK .
- No response/not equipped for the Generic Electronic Module (GEM), REFER to MULTIFUNCTION ELECTRONIC CONTROL MODULES , or for the 4-wheel drive (4WD) control module. REFER to FOUR- WHEEL DRIVE SYSTEMS .
- System passed, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs, and carry out self-test diagnostics for the GEM or the 4WD module.
- If the DTCs retrieved are related to the concern, go to GENERIC ELECTRONIC MODULE (GEM) or 4-WHEEL DRIVE (4WD) DIAGNOSTIC TROUBLE CODE (DTC) INDEX to continue diagnostics.
- If no DTCs related to the concern are retrieved, proceed to the SYMPTOM CHART to continue diagnostics.
