Pinpoint Test By : U3003:16
- BY1 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 BY2 No The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition. - BY2 CHECK FOR VOLTAGE RELATED (CHARGING SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS) IN THE DIRECT CURRENT (DC)/DIRECT CURRENT (DC) CONTROL MODULE
- Using a diagnostic scan tool, perform the DC/ DC converter module self-test.
Are any voltage related Diagnostic Trouble Codes (DTCs) recorded?
No GO to BY3 - BY3 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 BY4 No If the battery is discharged, DIAGNOSE the cause of the low battery condition.For HEV, REFER to: Direct Current/Direct Current (DC/DC) Converter Control Module - Hybrid Electric Vehicle (HEV) . For PHEV, REFER to: Direct Current/Direct Current (DC/DC) Converter Control Module - Plug-In Hybrid Electric Vehicle (PHEV) . If the battery condition fails, INSTALL a new battery. REFER to: Battery . - BY4 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) PID
Is the voltage within 0.2 volt of the recorded battery voltage?
Yes GO to BY7 No GO to BY5 - BY5 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) VOLTAGE SUPPLY
- Ignition OFF.
- Disconnect IPC C220.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C220-21 Ground
Is the voltage greater than 11 volts?
Yes GO to BY6 No REPAIR the circuit for high circuit resistance. - BY6 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) GROUND
Is the voltage greater than 11 volts?
Yes GO to BY7 No REPAIR the circuit for high circuit resistance. - BY7 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, Refer to IPC Guided Routine Testing . 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.
