NOTE:
Network communication/message DTCs may result from intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures such as module reprogramming often set these DTCs. To avoid repeat network concerns, INSPECT for damaged or corroded wiring at the APIM. Test the vehicle battery, refer to
CHARGING SYSTEM
. Replacing a module to resolve a network DTC is unlikely to resolve the concern. The module could not communicate on the network at a point in time. The fault is currently not present. CLEAR the DTC. REPEAT the network test with the scan tool. |
