DTC Charts: Notes

NOTE: Network DTCs (U-codes) are often a result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures such as module reprogramming often set network DTCs. Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery, refer to BATTERY, MOUNTING AND CABLES .

NOTE: Refer to DESCRIPTION AND OPERATION, Intelligent Access (IA) with Push Button Start in ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) to review the procedures for achieving the various ignition states (ignition off, ignition in accessory, ignition on, ignition start).
