April 5, 2026: LEMON Manuals is launched! Read the announcement.

Pinpoint Test M: DTC U3003:16

M1 CARRY OUT THE BODY CONTROL MODULE (BCM) SELF-TEST
NOTE: DTC U3003:16 will not clear unless the battery voltage is greater than 13V for 2 minutes.
- Ignition ON.
- Using a scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Using a scan tool, perform the BCM self-test.
  Is DTC U3003:16 still present?
  1. Yes: GO to M2
  2. No: The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.
M2 CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a scan tool, retrieve all continuous memory DTCs.
  Are any charging system DTCs recorded?
  1. Yes: REFER to: Charging System - 2.0L Duratec-HE ( CHARGING SYSTEM - 2.0L DURATEC-HE ).
    REFER to: Charging System - 2.0L EcoBoost ( CHARGING SYSTEM - 2.0L ECOBOOST ).
  2. No: GO to M3
M3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE
- Check the battery condition and verify the battery is fully charged.
  REFER to: Battery ( BATTERY ).
  
  Is the battery OK and fully charged?
  1. Yes: GO to M4
  2. No: CHARGE or INSTALL a new battery.
    REFER to: Battery ( BATTERY ).

M4 CHECK THE BODY CONTROL MODULE (BCM) VOLTAGE SUPPLY

Ignition OFF.
Disconnect: BCM C2280G .
Ignition ON.

Measure:

CLICK TO DISPLAY CONNECTORS

Positive Lead	Measurement / Action	Negative Lead
C2280G-1		-
C2280G-2		-

Are the voltages greater than 11 volts?

Yes: GO to M5
No: VERIFY the high current BJB fuse 9 (50A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM WIRING DIAGRAMS to identify the possible causes for the short circuit.

M5 CHECK THE BODY CONTROL MODULE (BCM) PROCESSOR GROUND

Disconnect: BCM C2280A .

Measure:

CLICK TO DISPLAY CONNECTORS

Positive Lead	Measurement / Action	Negative Lead
C2280A-3	Ω	-

Is the resistance less than 3 ohms?

Yes: GO to M6
No: REPAIR the circuit.

M6 CHECK FOR CORRECT BODY CONTROL MODULE (BCM) OPERATION
- Disconnect and inspect all BCM connectors.
- Repair:
  - corrosion (install new connector or terminals - clean module pins)
  - damaged or bent pins - install new terminals/pins
  - pushed-out pins - install new pins as necessary
- Connect the BCM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
  Is the concern still present?
  1. Yes: CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM.
    REFER to: Body Control Module (BCM) .
  2. 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.
