Pinpoint Test AR: 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 more than 250 milliseconds during normal operation or the self-test.

This pinpoint test is intended to diagnose the following:

- Charging system concern
- GPSM



PINPOINT TEST AS: DTC U3003:17 (GPSM)

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

-------------------------------------------------
AS1 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 AS2.

-------------------------------------------------
AS2 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 AS3.

-------------------------------------------------
AS3 RECHECK FOR DTC U3003:17


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

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