Pinpoint Test An: U0100:87

• Connect the scan tool.
• Check that a vehicle session can be established using the scan tool.

Can a vehicle session be established? 

• Yes  : GO to AN2 
• No  : REFER to: COMMUNICATIONS NETWORK .

• Check the vehicle service history for recent service actions related to the IPC  or the PCM  .

Have there been any recent service actions with either module? 

• Yes  : CARRY out a manual PMI  on the applicable module using As-Built data.
• No  : GO to AN3 

• 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 U0100:87 retrieved again? 

• Yes  : GO to AN4 
• 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.

• Using a diagnostic scan tool, perform the PCM KOEO  self-test.

Are any charging system DTC recorded? 

• Yes  : For 1.6L GTDI engine,

  REFER to: CHARGING SYSTEM - 1.6L ECOBOOST (132KW/180PS) - SIGMA .

  For 1.6L TiVCT engine,

  REFER to: CHARGING SYSTEM - 1.6L DURATEC-16V TI-VCT (88KW/120PS) - SIGMA .

• No  : GO to AN5 

• Using a diagnostic scan tool, perform the IPC  self-test.

Are any Diagnostic Trouble Codes (DTCs) retrieved? 

• Yes  : For DTC  U3006:16, GO to PINPOINT TEST AW 

  For DTC  U3006:17, GO to PINPOINT TEST AX 

  For all other Diagnostic Trouble Codes (DTCs), REFER to DTC CHART: IPC .

• No  : GO to AN6 

• 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 RCM ? 

• Yes  : GO to AN7 
• No  : GO to  AN8

• Ignition OFF.
• Disconnect and inspect the 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? 

• 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  .

  For 1.6L GTDI engine,

  REFER to: POWERTRAIN CONTROL MODULE (PCM) .

  For 1.6L TiVCT engine,

  REFER to: POWERTRAIN CONTROL MODULE (PCM) .

• 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.

• Ignition OFF.
