Pinpoint Test B: No Power In Acc

WARNING: This page is about a different car, the 2011 Ford Pickup, 2011 Ford F550 Super Duty, 2011 Ford F450 Super Duty, and 2011 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.
  1. B1 CHECK THE IGNITION SWITCH 
    • Carry out the Ignition Switch Component Test.

      Refer to appropriate System Wiring Diagrams article for component testing.

    • Is the ignition switch OK? 
    • Yes:  GO to  B2.
    • No:  INSTALL a new ignition switch. REFER to IGNITION SWITCH . TEST the system for normal operation.
  2. B2 CHECK VEHICLE EQUIPMENT 
    NOTE: The CDIM  is not installed on vehicles equipped with a gasoline engine and is optional for vehicles equipped with a diesel engine.
    • Verify the vehicle is equipped with a CDIM  .
    • Is the vehicle equipped with a CDIM  ?
    • Yes:  GO to  B5.
    • No:  GO to  B3.
  3. B3 CHECK THE RUN/ACC CIRCUIT FOR AN OPEN 
    • Disconnect: BCM  C2280B.
    • Disconnect: BCM  C2280A.
    • Ignition In ACC.
    • Measure the voltage between ground and:
      • BCM  C2280B-35, circuit CDC33 (VT/GN), harness side.
      • BCM  C2280A-10, circuit CDC33 (VT/GN), harness side.

    • Is the voltage greater than 10 volts? 
    • Yes:  GO to  B4.
    • No:  REPAIR circuit CDC33 (VT/GN) for an open. TEST the system for normal operation.
  4. B4 CHECK THE ELECTRICAL BCM CONNECTORS 
    • Check the BCM  electrical connectors C2280A and C2280B for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Repair any identified concerns.
    • Connect the BCM  connectors and make sure they are seated correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes:  INSTALL a new BCM  . REFER to MULTIFUNCTION ELECTRONIC MODULE . 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. TEST the system for normal operation.
  5. B5 REVIEW THE CDIM DTCs 
    • Review the CDIM  DTCs retrieved during Inspection and Verification.
    • Are any CDIM DTCs present? 
    • Yes:  For DTC B1359, GO to PINPOINT TEST F . For all other CDIM  DTCs, GO to the CDIM  DTC Chart.
    • No:  GO to  B6.
  6. B6 CHECK THE RUN/ACC CIRCUIT FOR AN OPEN 
    • Disconnect: BCM  C2280A.
    • Ignition In ACC.
    • Measure the voltage between BCM  C2280A-10, circuit CDC33 (VT/GN), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes:  GO to  B7.
    • No:  REPAIR the circuit CDC33 (VT/GN) for an open. TEST the system for normal operation.
  7. B7 CHECK THE RUN/ACC CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: BCM  C2280B.
    • Ignition In ACC.
    • Measure the voltage between BCM  C2280B-35, circuit CDC63 (YE/OG), harness side and ground.

    • Is the voltage greater than 10 volts? 
  8. B8 ISOLATE THE CDIM 
    • Disconnect: CDIM  C2500.
    • Connect a fused jumper wire between:
      • CDIM  C2500-1, CDC33 (VT/GN), harness side and CDIM  C2500-8, CDC63 (YE/OG), harness side.
