- Charging system concern

- FCDIM (Front Control/Display Interface Module)

PINPOINT TEST AF : DTC U3003:17 (FCDIM (Front Control/Display Interface Module))

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

AF1 CHECK FOR HIGH VOLTAGE DTCs SET IN OTHER MODULES

- Ignition ON.

- Retrieve the continuous memory DTCs from all modules.

Are high voltage DTCs (e.g., B1317, U3003:17, P0563) set in more than one module?

Yes
REFER to Battery to diagnose an overcharging.

No
GO to AF2.

AF2 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.

No
GO to AF3.

AF3 RECHECK FOR DTC U3003:17

- Ignition OFF.

- Ignition ON.

- Clear the FCDIM (Front Control/Display Interface Module) DTCs.

- Repeat the FCDIM (Front Control/Display Interface Module) self-test.

Is DTC U3003:17 present?

Yes
INSTALL a new FCDIM (Front Control/Display Interface Module). REFER to Front Controls/Display Interface Module (FCDIM) Front Controls/Display Interface Module (FCDIM). TEST the system for normal operation.

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.
