- DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition IPC U3003:17 Battery Voltage: Circuit Voltage Above Threshold Sets in the IPC in continuous memory if the IPC detects battery voltage above 16 volts on the voltage supply circuit for 5 seconds or longer. Possible Sources
- Charging system concern
- IPC
- NOTE: DTC U3003:17 may be stored in the module memory due to past battery charging or vehicle jump starting events.
- BT1 CHECK FOR OVERCHARGING DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES
- Ignition ON.
- Using a diagnostic scan tool, perform self-test on all modules.
- Retrieve the continuous memory DTCs from all modules.
Are any overcharging Diagnostic Trouble Codes (DTCs) DTC set in more than one module?
Yes DIAGNOSE the overcharging condition. REFER to: Charging System . No GO to BT2 - BT2 CHECK THE BATTERY VOLTAGE
- Turn off all interior/exterior lights and accessories.
- Start and run the motor for approximately 3 minutes while monitoring the battery voltage.
Does the battery voltage rise to 15.5 volts or higher?
Yes DIAGNOSE the overcharging condition. REFER to: Charging System . No GO to BT3 - BT3 RECHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U3003:17
- Ignition OFF.
- Ignition ON.
- Using a diagnostic scan tool, clear the continuous memory DTCs.
- Carry out the IPC self-test.
Is DTC U3003:17 present?
Yes INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) . No The system is operating correctly at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle.
