Normal Operation
- DTC U3003:17 (Battery Voltage: Circuit Voltage Above Threshold) - set by the Front Controls Interface Module (FCIM) when the supply voltage is greater than 15.8 volts for more than 250 milliseconds during normal operation or the self-test.

This pinpoint test is intended to diagnose the following:

- Charging system concern
- FCIM



PINPOINT TEST AV: DTC U3003:17 (FCIM)

NOTE: DTC U3003:17 may be stored in the module memory due to past battery charging or vehicle jump starting events.

-------------------------------------------------
AV1 CHECK FOR HIGH VOLTAGE DTCs SET IN OTHER MODULES


- Ignition ON.
- Retrieve all continuous DTCs from all modules.
- Is DTC B1317, B1676, or B0563 (PCM), or U3003:17 set in more than one module?

Yes
REFER to Charging System to diagnose an overcharging condition.

No
GO to AV2.

-------------------------------------------------
AV2 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 15.5 volts or higher?

Yes
REFER to Charging System to diagnose an overcharging condition.

No
GO to AV3.

-------------------------------------------------
AV3 RECHECK FOR DTC U3003:17


- Turn the engine off.
- Ignition ON.
- Clear the FCIM DTCs.
- Repeat the FCIM self-test.
- Is DTC U3003:17 present?

Yes
INSTALL a new FCIM. REFER to Front Controls Interface Module (FCIM) - Fusion, Milan Front Controls Interface Module (FCIM) or Front Controls Interface Module (FCIM) - MKZ Front Controls Interface Module (FCIM). TEST this system for normal operation.

No
The system is operating normally at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle.
