Pinpoint Test Q : U3003:16

WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: Failure to disconnect the battery when instructed results in false resistance readings. Refer to BATTERY DISCONNECT AND CONNECT .

Q1 RECHECK THE CCM (CRUISE CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a diagnostic scan tool, perform the self-test.
Is DTC U3003:16 still present?

Yes GO to Q2

No The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.

Q2 CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS) IN THE PCM (POWERTRAIN CONTROL MODULE)

Using a diagnostic scan tool, perform the PCM self-test.

Are any charging system Diagnostic Trouble Codes (DTCs) present in the PCM?

Yes	For 2.0L GTDI, REFER to: Charging System - 2.0L EcoBoost (184kW/250PS) - MI4 . For 2.7L GTDI and 3.5L TiVCT, CHARGING SYSTEM - 2.7L ECOBOOST (238KW/324PS)/3.5L DURATEC (212KW/278PS)

GO to Q3

Q3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE
- Check the battery condition and verify the battery is fully charged. REFER to: Battery .
Is the battery OK and fully charged?

Yes GO to Q4

No INSTALL a new battery. REFER to: Battery .

Q4 CHECK THE CCM (CRUISE CONTROL MODULE) VOLTAGE SUPPLY

Ignition OFF.

Disconnect CCM C1582.

Ignition ON.

Measure and record the voltage at the battery.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C1582-10	Courtesy of FORD MOTOR COMPANY	Ground

Is the voltage within 0.2 volt of the recorded battery voltage?

Yes

GO to Q5

No	REPAIR the circuit for high resistance.

Q5 CHECK THE CCM (CRUISE CONTROL MODULE) GROUND CIRCUIT

Ignition OFF.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C1582-4	Courtesy of FORD MOTOR COMPANY	Ground

Is the resistance less than 3 ohms?

Yes

GO to Q6

No	REPAIR the circuit for high resistance.

Q6 CHECK FOR CORRECT CCM (CRUISE CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect the CCM connector and related in-line connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect the CCM connector and related in-line connector. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new CCM. REFER to: Cruise Control Module (CCM) .

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
