Diagnostic Routine BD
Diagnostic Overview
U3003:16
Refer to Wiring Diagram Set 60 for schematic and connector information Electrical Diagrams.
Normal Operation and Fault Conditions
IPC (Instrument Panel Cluster) DTC Fault Trigger Conditions
Pinpoint Test
1. RECHECK THE IPC (Instrument Panel Cluster) DTCs (Diagnostic Trouble Codes)
1. Ignition ON.
2. Using a scan tool, perform the IPC (Instrument Panel Cluster) self-test.
3. Clear the DTCs (Diagnostic Trouble Codes).
4. Wait 10 seconds.
5. Repeat the IPC (Instrument Panel Cluster) self-test.
Is DTC (Diagnostic Trouble Code) U3003:16 still present?
2. CHECK FOR CHARGING SYSTEM DTCs (Diagnostic Trouble Codes) IN THE PCM (Powertrain Control Module)
1. Using a scan tool, perform the PCM (Powertrain Control Module) self-test.
2. Carry out the PCM (Powertrain Control Module) KOEO (Key ON Engine OFF) self-test.
Is DTC (Diagnostic Trouble Code) P0620, P0622, P0625, P0626 or P065B set in the PCM (Powertrain Control Module)?
3. CHECK THE BATTERY CONDITION AND STATE OF CHARGE
1. Check the battery condition and verify the battery is fully charged. REFER to Diagnostic Routine A: Battery Condition Test Pinpoint Tests.
Is the battery OK and fully charged?
4. CHECK THE IPC (Instrument Panel Cluster) VOLTAGE PID (Parameter Identification) (MODULE_VOLT)
1. Ignition ON.
2. Measure and record the voltage at the battery.
3. Using a scan tool, view the IPC (Instrument Panel Cluster) PIDs (Parameter Identifications).
4. Select and monitor the IPC (Instrument Panel Cluster) voltage PID (Parameter Identification) (MODULE_VOLT).
Is the voltage within 0.2 volt of the recorded battery voltage?
5. CHECK THE IPC (Instrument Panel Cluster) VOLTAGE SUPPLY
1. Ignition OFF.
2. Disconnect: IPC (Instrument Panel Cluster).
3. Ignition ON.
4. Measure:
Is the voltage within 0.2 volt of the recorded battery voltage?
6. CHECK THE IPC (Instrument Panel Cluster) GROUND CIRCUIT
1. Ignition OFF.
2. Measure:
Is the resistance less than 3 ohms?
7. CHECK FOR CORRECT IPC (Instrument Panel Cluster) OPERATION
1. Disconnect and inspect the IPC (Instrument Panel Cluster) connector.
2. 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
3. Reconnect the IPC (Instrument Panel Cluster) connector. Make sure it seats and latches correctly.
4. Operate the system and determine if the concern is still present.
Is the concern still present?
