Pinpoint Test P: DTC U3003:17

Remote Function Actuator (RFA) Module

Pinpoint Test P: DTC U3003:17

Normal Operation
- DTC U3003:17 (Battery Voltage: Circuit Voltage Above Threshold) - sets in the Remote Function Actuator (RFA) module when the RFA module detects that battery voltage exceeds 16 volts from the voltage supply circuit.

This pinpoint test is intended to diagnose the following:

- Charging system concern
- RFA module

PINPOINT TEST P: DTC U3003:17

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

P1 CHECK FOR DTC B1317, B1676, P0563 (PCM) OR U3003:17 SET IN OTHER MODULES

- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self-Test.
- Retrieve the continuous memory DTCs from all modules.
- Is DTC B1317, B1676, P0563 (PCM) or U3003:17 set in more than one module?

Yes
REFER to Charging System Testing and Inspection to diagnose an overcharging condition.

No
GO to P2.

-------------------------------------------------
P2 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 16 volts or higher?

Yes
REFER to Charging System Testing and Inspection to diagnose an overcharging condition.

No
GO to P3.

-------------------------------------------------
P3 RECHECK FOR DTC U3003:17

- Turn the engine off.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: RFA Module Self-Test.
- Clear the continuous memory DTCs.
- Carry out the RFA module self-test.
- Is DTC U3003:17 present?

Yes
INSTALL a new RFA module. REFER to Remote Function Actuator (RFA) Module 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.
