- CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to MODULE COMMUNICATIONS NETWORK .
- NO RESP/NOT EQUIP for rear electronics module, refer to MULTIFUNCTION ELECTRONIC MODULE .
- NO RESP/NOT EQUIP for driver seat module, refer to MULTIFUNCTION ELECTRONIC MODULE .
- SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out self-test diagnostics for the rear electronics module or the driver seat module.
- If the DTCs retrieved are related to the concern, go to the REAR ELECTRONICS MODULE DIAGNOSTIC TROUBLE CODE (DTC) INDEX or the DRIVER SEAT MODULE DIAGNOSTIC TROUBLE CODE (DTC) INDEX to continue diagnostics.
