Pinpoint Test G: DTC B10DA:86 And/Or DTC U0100:00

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

G1 CHECK THE BATTERY STATE OF CHARGE
- Ignition OFF.
- Check the battery state of charge with the battery condition test. Refer to BATTERY, MOUNTING & CABLES -- FUSION, MILAN & MKZ article.
- Does the battery pass the battery condition test?
- Yes : GO to G2 .
- No : INSTALL a new battery. REFER to BATTERY, MOUNTING & CABLES -- FUSION, MILAN & MKZ article.
G2 CHECK FOR MODULE COMMUNICATION ON THE HS-CAN
- Connect the scan tool.
- Ignition ON.
- Carry out the network test using the scan tool.
- Is the scan tool unable to communicate with any of the modules on the HS-CAN?
- Yes : REFER to MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ article to diagnose the module that is not communicating with the scan tool.
- No : GO to G3 .
G3 INSPECT THE HS-CAN CIRCUITRY
- Ignition OFF.
- Inspect all of the HS-CAN circuitry, including the pin crimps, connector fit, corroded/bent/pushed-out/damaged pins and splice integrity in the 4 splices and 36 connections (8 connectors) between the PCM and the IPC.
- Does the HS-CAN circuitry pass the component inspection?
- Yes : GO to G4 .
- No : REPAIR the HS-CAN circuitry as necessary. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
G4 CHECK FOR CORRECT PCM OPERATION
- Disconnect all the PCM connectors.
- Check for:
  - corrosion
  - damaged pins
  - pushed-out pins
- Connect all the PCM connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new PCM. Refer to the appropriate service information in ELECTRONIC ENGINE CONTROLS for the procedure. RESET the parameters in both the IPC and the PCM. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET in this service information. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation. If the concern is still present, GO to G5 .
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
G5 CHECK FOR CORRECT IPC OPERATION
- Disconnect all the IPC connectors.
- Check for:
  - corrosion
  - damaged pins
  - pushed-out pins
- Connect all the IPC connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new IPC. REFER to INSTRUMENTATION, MESSAGE CENTER & WARNING CHIMES -- FUSION, MILAN & MKZ article. RESET the parameters in both the IPC and the PCM. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET in this service information. PROGRAM the PATS keys into the new IPC. REFER to INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT in this service information. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
