Pinpoint Test Bk: DTC U3003:16
WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. 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, MOUNTING AND CABLES
.
- BK1 RECHECK THE IPC DTCs
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IPC Self-Test.
- Clear the DTCs.
- Wait 10 seconds.
- Repeat the IPC self-test.
- Is DTC U3003:16 still present?
- Yes : GO to BK2.
- No : The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.
- BK2 CHECK FOR CHARGING SYSTEM DTCs IN THE PCM
- Enter the following diagnostic mode on the scan tool: PCM Self-Test.
- Carry out the PCM Key ON Engine OFF (KOEO) self-test.
- Retrieve the continuous memory DTCs from all modules.
- Is DTC P0620, P0622, P0625, P0626 or P065B set in the PCM?
- Yes : REFER to CHARGING SYSTEM .
- No : GO to BK3.
- BK3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE
- Check the battery condition and verify the battery is fully charged. Refer to BATTERY, MOUNTING AND CABLES .
- Is the battery OK and fully charged?
- Yes : GO to BK4.
- No : REFER to BATTERY, MOUNTING AND CABLES .
- BK4 CHECK THE IPC VOLTAGE SUPPLY
- Measure and record the voltage at the battery.
- Ignition OFF.
- Disconnect: IPC C220.
- Ignition ON.
- Measure the voltage between the IPC C220-6, circuit SBP11 (BU/RD or YE/RD), harness side and ground.
- Is the voltage within 0.2 volt of the recorded battery voltage?
- Yes : GO to BK5.
- No : REPAIR circuit SBP26 (YE/RD) for high resistance. CLEAR the DTC. REPEAT the self-test.
- BK5 CHECK THE IPC GROUND CIRCUIT
- Ignition OFF.
- Disconnect: Negative Battery Cable.
- Measure the resistance between the IPC C220-22, circuit GD184 (BK/GY or BK/YE), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes : GO to BK6.
- No : REPAIR circuit GD114 (BK/BU) for high resistance. CLEAR the DTCs. REPEAT the self-test.
- BK6 CHECK FOR CORRECT IPC OPERATION
- Disconnect the IPC connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the IPC connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new IPC. REFER to INSTRUMENT PANEL CLUSTER (IPC) . TEST the system for normal operation.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
