DTC Fault Trigger Conditions






Pinpoint Test

1. RECHECK FOR DTC (Diagnostic Trouble Code) U3003:16

1. Ignition ON.

2. Using a scan tool, clear the DTCs (Diagnostic Trouble Codes) for the module in question.

3. Wait 15 seconds.

4. Using a scan tool, repeat the 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 the scan tool, retrieve the continuous memory DTCs (Diagnostic Trouble Codes) from all modules.

Are any voltage-related DTCs (Diagnostic Trouble Codes) set in the PCM (Powertrain Control Module)?






3. CHECK THE BATTERY CONDITION AND STATE OF CHARGE

1. Check the battery condition and verify that 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 MODULE VOLTAGE SUPPLY

1. Ignition OFF.

2. Measure and record the voltage at the battery.

3. Disconnect the IPM-B (Image Processing Module - B).

4. Ignition ON.

5. Measure:





Is the voltage at the suspect module within 0.2 volt of the recorded battery voltage?






5. CHECK THE MODULE GROUND CIRCUIT FOR CONTINUITY

1. Measure:





Is the suspect module voltage greater than 11 volts?






6. CHECK FOR CORRECT IPM-B (Image Processing Module - B) OPERATION

1. Disconnect the IPM-B (Image Processing Module - B) connector.

2. Repair:

- corrosion (install new connector or terminals- clean module pins)
- damaged pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

3. Reconnect the IPM-B (Image Processing Module - B) connector and make sure it seats and latches correctly.

4. Operate the system and determine if the concern is still present.

Is the concern still present?
