Pinpoint Test BD: U0100:00 Or U0401:82

BD1 VERIFY THE SCAN TOOL COMMUNICATES WITH THE PCM (POWERTRAIN CONTROL MODULE)
- Connect the scan tool.
- Check that a vehicle session can be established using the scan tool.
Can a vehicle session be established?
1. Yes : GO to BD2
2. No : REFER to: COMMUNICATIONS NETWORK - 2.0L DURATEC - HYBRID (96KW/130PS) .
BD2 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Ignition ON.
- Using a diagnostic scan tool, perform the IPC self-test.
- Clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Repeat the IPC self-test.
Is DTC U0100:00 or U0401:82 retrieved again?
1. Yes : GO to BD3
2. No : The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.
BD3 PERFORM THE PCM (POWERTRAIN CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the PCM self-test.
Are any DTC recorded?
1. Yes : REFER to: ELECTRONIC ENGINE CONTROLS .
2. No : GO to BD4
BD4 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Is DTC U3006:16 or DTC U3006:17 recorded?
1. Yes : REFER to DTC CHART: IPC .
2. No : GO to BD5
BD5 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
(DTCs).

Are any Diagnostic Trouble Codes (DTCs) set?
1. Yes : REFER to: COMMUNICATIONS NETWORK - 2.0L DURATEC - HYBRID (96KW/130PS) .
2. No : GO to BD6
BD6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0100:00 OR DTC (DIAGNOSTIC TROUBLE CODE) U0100:87 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, perform the continuous memory self-test.
- Retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0100:00 set in the ABS module or DTC U0100:87 set in the BCM?
1. Yes : GO to BD7
2. No : GO to BD8
BD7 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect PCM 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 PCM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
1. 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 PCM .
  REFER to: POWERTRAIN CONTROL MODULE (PCM) .
2. 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.
BD8 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect 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?
1. 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) .
2. 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.
