Pinpoint Test Be: U3003:16

BE1 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 BE2
- No : The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.
BE2 CHECK FOR VOLTAGE RELATED (CHARGING SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS) IN THE DIRECT CURRENT (DC)/DIRECT CURRENT (DC) CONVERTER CONTROL MODULE
- Using a diagnostic scan tool, perform the DC/DC converter control module self-test.
Are any voltage related Diagnostic Trouble Codes (DTCs) recorded?
- Yes : REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) .
- No : GO to BE3
BE3 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 BE4
- No : If the battery is discharged, DIAGNOSE the cause of the low battery condition.
  REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) .
  
  If the battery condition check fails, INSTALL a new battery.
  
  REFER to: BATTERY .
BE4 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) VOLTAGE PID
- 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) Parameter Identification (PID)
Is the voltage within 0.2 volt of the recorded battery voltage?
- Yes : GO to BE7
- No : GO to BE5

BE5 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) VOLTAGE SUPPLY

Ignition OFF.
Disconnect IPC .
Ignition ON.

Measure:

Positive Lead	Measurement/Action	Negative Lead
C220-21		Ground

Is the voltage greater than 11 volts?

Yes : GO to BE6
No : REPAIR the circuit.

BE6 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) GROUND

Measure:

Positive Lead	Measurement/Action	Negative Lead
C220-21		C220-5

Is the voltage greater than 11 volts?

Yes : GO to BE7
No : REPAIR the circuit.

BE7 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPC connector.
- 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 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 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.
