Pinpoint Test Q: U3003:16
WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
- Q1 RECHECK THE C-CM DTCs
- Ignition ON.
- Using a scan tool, perform the C-CM self-test.
- Clear the DTCs .
- Wait 10 seconds.
- Repeat the C-CM 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 DTCs IN THE PCM
- Using a scan tool, perform PCM Self-Test.
- Retrieve the continuous memory DTCs from the PCM .
Are any charging system DTCs present in the PCM ?
- Yes : REFER to ELECTRONIC ENGINE CONTROLS .
- No : GO to Q3 .
- Q3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE
- Check the battery condition and verify that the battery is fully charged. REFER to GO TO PINPOINT TEST A .
Is the battery OK and fully charged?
- Yes : GO to Q4 .
- No : REFER to BATTERY CHARGING .
- Q4 CHECK THE C-CM VOLTAGE SUPPLY
- Ignition OFF.
- Measure and record the voltage at the battery.
- Disconnect C-CM .
- Ignition ON.
- Measure:
Positive Lead Measurement/Action Negative Lead C1582-1 Ground C1582-10 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 C-CM GROUND CIRCUIT
Is the resistance less than 3 ohms?
- Yes : GO to Q6 .
- No : REPAIR the circuit for high resistance.
- Q6 CHECK FOR CORRECT C-CM OPERATION
- Disconnect and inspect the C-CM connector.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the C-CM connector. Make sure it seats and latches correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
- Yes : CHECK OASIS for any applicable TSBs . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new C-CM . Refer to CRUISE-CONTROL MODULE (C-CM)
- 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.
