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

Pinpoint Test N: DTC (Diagnostic Trouble Code) U3003:16

N1 CARRY OUT THE BCM (BODY CONTROL MODULE) SELF-TEST
- Ignition ON.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, perform the BCM self-test.
Is DTC U3003:16 still present?
- Yes : GO to N2
- No : The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.
N2 CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Are any charging system DTC recorded?
- Yes : REFER to: CHARGING SYSTEM - 1.6L ECOBOOST (132KW/180PS) - SIGMA .
  REFER to: CHARGING SYSTEM - 2.5L DURATEC (125KW/170PS) .
- No : GO to N3
N3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE
- Check the battery condition and verify the battery is fully charged.
  REFER to: BATTERY .
Is the battery OK and fully charged?
- Yes : GO to N4
- No : CHARGE or INSTALL a new battery.
  REFER to: BATTERY - 1.6L ECOBOOST (132KW/180PS) - SIGMA .

N4 CHECK THE BCM (BODY CONTROL MODULE) VOLTAGE SUPPLY

Ignition OFF.
Disconnect: BCM C2280G .
Ignition ON.

Measure:

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

Are the voltages greater than 11 volts?

Yes : GO to N5
No : VERIFY the high current BJB MEGA fuse 4 (50A) and MEGA fuse 9 (50A) are OK. If OK, REPAIR the circuit in question. If not OK, REFER to the OEM WIRING DIAGRAMS to identify the possible causes for the high circuit resistance.

N5 CHECK THE BCM (BODY CONTROL MODULE) PROCESSOR GROUND

Disconnect: BCM C2280A .

Measure:

Positive Lead	Measurement/Action	Negative Lead
C2280A-3		Ground

Is the resistance less than 3 ohms?

Yes : GO to N6
No : REPAIR the circuit for high resistance.

N6 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) 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
- Reconnect 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?
- 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) .
- 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.
