WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
- T1 CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS) IN THE BCM (BODY CONTROL MODULE)
- Ignition ON.
- Using a diagnostic scan tool, perform the BCM self-test.
Are any charging system Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to the DTC Chart: Body Control Module (BCM) . No GO to T2 - T2 CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES
- Ignition ON.
- Using a diagnostic scan tool, retrieve all Diagnostic Trouble Codes (DTCs).
Are any charging system Diagnostic Trouble Codes (DTCs) recorded?
Yes DIAGNOSE the charging system concern. REFER to: Charging System - 2.7L EcoBoost (238kW/324PS)/3.5L EcoBoost (272kW/370PS) . REFER to: Charging System - 3.3L Duratec-V6/5.0L 32V Ti-VCT . No GO to T3 - T3 CHECK THE BATTERY VOLTAGE
- Turn off all interior/exterior lights and accessories.
- Start and run the engine at approximately 2, 000 rpm for 3 minutes while monitoring the battery voltage.
Positive Lead Measurement / Action Negative Lead
Does the battery voltage rise to 16 volts or higher?
Yes DIAGNOSE the charging system concern. REFER to: Charging System - 2.7L EcoBoost (238kW/324PS)/3.5L EcoBoost (272kW/370PS) . REFER to: Charging System - 3.3L Duratec-V6/5.0L 32V Ti-VCT . No GO to T4 - T4 RECHECK THE BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition OFF.
- Ignition ON.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, check the BCM Diagnostic Trouble Codes (DTCs).
Is DTC U3006:1C present?
Yes GO to T5 No The system is operating correctly at this time. The DTC may have been caused by module connections or may have been set previously during battery charging or while jump starting the vehicle. ADDRESS the root cause of any connector or pin issues. - T5 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 T6 No If the battery is discharged, DIAGNOSE the cause of the low battery condition. REFER to: Charging System - 2.7L EcoBoost (238kW/324PS)/3.5L EcoBoost (272kW/370PS) . REFER to: Charging System - 3.3L Duratec-V6/5.0L 32V Ti-VCT . If the battery condition fails, INSTALL a new battery. REFER to: Battery . - T6 COMPARE THE BCM (BODY CONTROL MODULE) BATTERY VOLTAGE (V_BATT_BCM) PID (PARAMETER IDENTIFICATION) WITH THE ACTUAL BATTERY VOLTAGE
- Start the engine.
- Turn on accessories (climate control blower on high speed, exterior lights).
- With the engine running at idle, measure and record battery voltage:
Positive Lead Measurement / Action Negative Lead
- Using a diagnostic scan tool, view the BCMPID V_BATT_BCM.
Is the recorded battery voltage within 0.2 volt of the PID?
Yes GO to T9 No GO to T7 - T7 CHECK THE BCM (BODY CONTROL MODULE) VOLTAGE SUPPLY CIRCUIT
- Ignition OFF.
- Disconnect BCM C2280G.
- Disconnect BCM C2280H.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C2280G-17 Ground C2280G-21 Ground C2280G-22 Ground Positive Lead Measurement / Action Negative Lead C2280H-1 Ground
Is the voltage within 0.2 volt of the recorded battery voltage?
Yes GO to T8 No REPAIR the circuit for high resistance. - T8 CHECK THE BCM (BODY CONTROL MODULE) PROCESSOR GROUNDS
- Ignition OFF.
- Disconnect BCM C2280C.
Are the resistances less than 3 ohms?
Yes GO to T9 No REPAIR the circuit in question for high resistance. - T9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect the BCM and all related in-line 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 and all related in-line 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, follow TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Refer to BCM GUIDED ROUTINE . 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.
