DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition DDM U3003:17 Battery Voltage: Circuit Voltage Above Threshold Set by the DDM when the supply voltage is more than 15.8 volts for more than 250 milliseconds during normal operation or the self-test. PDM U3003:17 Battery Voltage: Circuit Voltage Above Threshold Set by the PDM when the supply voltage is more than 15.8 volts for more than 250 milliseconds during normal operation or the self-test. Possible Sources
- Previous high battery voltage
- Wiring, terminals, or connectors
- DDM
- PDM
- AF1 RECHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U3003:17
- Ignition ON.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs) for the door module in question.
- Wait at least 10 seconds.
- Using a diagnostic scan tool, perform the self-test for the door module in question.
Is DTC U3003:17 present?
Yes GO to AF2 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. - AF2 CHECK FOR HIGH VOLTAGE DIAGNOSTIC TROUBLE CODES (DTCS) SET IN MULTIPLE MODULES
- Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Are high voltage Diagnostic Trouble Codes (DTCs) such as B1676, P0563, or U3003:17 set in more than one module?
Yes REFER to: Charging System - 2.7L EcoBoost (238kW/324PS)/3.5L EcoBoost (BM) . REFER to: Charging System - 3.3L Duratec-V6/5.0L 32V Ti-VCT . REFER to: Charging System - 3.0L Power Stroke Diesel . No GO to AF3 - AF3 CHECK THE BATTERY VOLTAGE
- Turn off all interior lights, exterior lights, and accessories.
- Start and run the engine at approximately 2, 000 RPM for 3 minutes while monitoring the battery voltage.
Does the battery voltage rise to 15.5 volts or higher?
Yes REFER to: Charging System - 2.7L EcoBoost (238kW/324PS)/3.5L EcoBoost (BM) . REFER to: Charging System - 3.3L Duratec-V6/5.0L 32V Ti-VCT . REFER to: Charging System - 3.0L Power Stroke Diesel . See: Symptom Chart, System voltage high. No GO to AF4 - AF4 CHECK FOR CORRECT DDM (DRIVER DOOR MODULE) / PDM (PASSENGER DOOR MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect the door module connector in question.
- Repair:
- Corrosion (clean module pins or install new connectors or terminals)
- Damaged or bent pins (install new terminals or pins)
- Pushed-out pins (install new pins as necessary)
- Reconnect the door module connector. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new DDM/ PDM. REFER to: Driver Door Module (DDM) . REFER to: Passenger Door Module (PDM) . No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
