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

Information and Entertainment System

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

Normal Operation

- 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 greater 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 AH : DTC U3003:17 (GPSM (Global Positioning System Module))

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

AH1 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 AH2.

AH2 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 AH3.

AH3 RECHECK FOR DTC U3003:17

- Ignition OFF.

- Ignition ON.

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

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

Is DTC U3003:17 present?

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