Pinpoint Test H : DTC (Diagnostic Trouble Code) U3003:17, P1397:00
NOTE:
DTC U3003:17 may be stored in the module memory due to previous battery charging or vehicle jump starting events.
- H1 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 Diagnostic Trouble Codes (CM DTCs) from all modules.
Are any high voltage Diagnostic Trouble Codes (DTCs) recorded in more than one module?
Yes DIAGNOSE the overcharging condition. REFER to: Charging System - 1.6L EcoBoost (132kW/180PS) - Sigma . REFER to: Charging System - 1.6L Duratec-16V Ti-VCT (88kW/120PS) - Sigma . No GO to H2 - H2 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.
Does the battery voltage rise to 16.7 volts or higher?
Yes DIAGNOSE the overcharging condition. REFER to: Charging System - 1.6L EcoBoost (132kW/180PS) - Sigma . REFER to: Charging System - 1.6L Duratec-16V Ti-VCT (88kW/120PS) - Sigma . No GO to H3 - H3 RECHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U3003:17
- Turn the engine off.
- Ignition ON.
- Using a diagnostic scan tool, clear the Continuous Memory Diagnostic Trouble Codes (CM DTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, check the BCM Continuous Memory Diagnostic Trouble Codes (CM DTCs).
Is DTC U3003:17 still present?
Yes GO to H4 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. - H4 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 DTC may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
