Pinpoint Test Ch : U3003:16
- CH1 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 CH2 No The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition. - CH2 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 CH3 - CH3 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 CH4 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 . - CH4 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 CH7 No GO to CH5 - CH5 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 CH6 No REPAIR the circuit for high circuit resistance. - CH6 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) GROUND
Is the voltage greater than 11 volts?
Yes GO to CH7 No REPAIR the circuit for high circuit resistance. - CH7 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, 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.
