NOTE:
Network communication/message DTCs may result from intermittent concerns with damaged wiring or low battery voltage. 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 Battery Condition Test in
BATTERY, MOUNTING AND CABLES
. Refer to
CHARGING SYSTEM
for more information. 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 not currently present. CLEAR the DTC. REPEAT the network test with the scan tool. |
| U3003:16 | Battery Voltage: Circuit Voltage Below Threshold | GO to PINPOINT TEST L . |
| U3003:17 | Battery Voltage: Circuit Voltage Above Threshold | GO to PINPOINT TEST M . |
