Information and Entertainment System

Pinpoint Test BC: DTC U3003:17 (Global Positioning System Module (GPSM))

- DTC U3003:17 (Battery Voltage: Circuit Voltage Above Threshold)- set by the Global Positioning System Module (GPSM) 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

- GPSM (Global Positioning System Module)

PINPOINT TEST BC : DTC U0151:00

BC1 CHECK FOR HIGH VOLTAGE DTCs SET IN OTHER MODULES

- Ignition ON.

- Retrieve all continuous DTCs from all modules.

Are any high voltage DTCs set in any modules?

Yes
GO to BC2.

No
The system is operating correctly at this time. The DTC may have been set due to an intermittent fault in the network wiring.

BC2 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 BC3.

BC3 RECHECK FOR DTC U3003:17

- Turn the engine off.

- Ignition ON.

- Clear the GPSM (Global Positioning System Module) DTCs.

- Repeat the GPSM (Global Positioning System Module) self-test.

Is DTC U3003:17 still present?

Yes
INSTALL a new GPSM (Global Positioning System Module). REFER to Global Positioning System Module (GPSM) . 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.
