Normal Operation and Fault Conditions

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
IPC U3003:16	Battery Voltage: Circuit Voltage Below Threshold	Sets in the IPC in continuous memory if the IPC detects battery voltage below 9 volts on the voltage supply circuit for 5 seconds or longer.

Possible Sources

Wiring, terminals or connectors
High circuit resistance
Charging system concern
IPC

BP1 RECHECK THE IPC (INSTRUMENT PANEL CLUSTER) DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, perform the IPC self-test.
Is DTC U3003:16 still present?

Yes GO to BP2

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

BP2 CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS) IN THE BCM (BODY CONTROL MODULE)
- Using a diagnostic scan tool, perform the BCM self-test.
Are any charging system Diagnostic Trouble Codes (DTCs) recorded?

Yes REFER to: Body Control Module (BCM) .

No GO to BP3

BP3 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 BP4

No	If the battery is discharged, DIAGNOSE the cause of the low battery condition. REFER to: Battery . If the battery condition fails, INSTALL a new battery. REFER to: Battery .

BP4 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) VOLTAGE PID (PARAMETER IDENTIFICATION)
- Measure and record the voltage at the battery.
- Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).
- Monitor the IPC voltage (MODULE_VOLT) PID
Is the voltage within 0.2 volt of the recorded battery voltage?

Yes GO to BP7

No GO to BP5

BP5 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) VOLTAGE SUPPLY

Ignition OFF.

Disconnect IPC C220.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C220-8	Courtesy of FORD MOTOR COMPANY	Ground

Is the voltage greater than 11 volts?

Yes

GO to BP6

No	REPAIR the circuit for high circuit resistance.

BP6 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) GROUND

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C220-8	Courtesy of FORD MOTOR COMPANY	Refer to C220-3

Is the voltage greater than 11 volts?

Yes

GO to BP7

No	REPAIR the circuit for high circuit resistance.

BP7 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION

Ignition OFF.

Disconnect and inspect the IPC and all 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 IPC and all related in-line connectors. 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 IPC. REFER to: Instrument Panel Cluster (IPC) .

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.
