Pinpoint Test T: DTCs B106E, B106F

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Normal Operation and Fault Conditions

The DDM controls the output of several vehicle systems by means of solid state drivers. A DTC sets when an overload occurs on any of these drivers. The module also tracks the number of repetitive faults on each of these circuits, and then it compares that said number of overloads to 3 progressive thresholds established for each circuit. If the third threshold has not been met, the DTC for the affected circuit can be cleared by eliminating the fault, clearing the DTCs and then running a self-test.

At the point that each of the first 2 thresholds is met, DTC B106E sets along with a DTC related to the affected circuit. Once the final (third) threshold has been met, the affected output is permanently disabled, and DTC B106F sets, at which time the DDM must be replaced.



  DDM DTC Fault Trigger Conditions

DTC Description Fault Trigger Conditions
B106E Solid State Driver Disabled Due to Short Circuit Sets when the DDM has disabled an output circuit due to a repetitive fault that overloads said circuit. A corresponding DTC for the circuit in question is also set.
B106F Module Disabled Due to External Fault Sets when the DDM has permanently disabled one or more output functions due to a repetitive circuit overload. DTC B1342 also sets at this time.

When DTC B1342 is set because the module has reached a third threshold and the DDM has permanently disabled an output, no DTCs can be cleared from the DDM . Using the module self-test to confirm a repair is not possible and a measurement using a digital multimeter of the affected output circuit is required to make sure the fault condition no longer exists.

 
PINPOINT TEST T: DTCs B106E, B106F
Test Step Result / Action to Take
  T1 REVIEW THE DTCs  

    NOTICE: First follow the necessary diagnostics to resolve DTC B106E and any other present DTCs (ignoring B106F). DTC B106E is only present when there is another DTC due to software or circuitry issues that must be resolved before another self-test is run. DTC B106F is only present once the final threshold has been met. Failure to correct the fault condition first may cause damage to the new DDM , resulting in a repeat repair.

  • Review the DTCs from the DDM self-test.
  • Are any other DTCs present, besides B106E, B106F or B1342?
Yes
CORRECT the DTCs. REFER to Driver Door Module (DDM) DTC Chart in this section. After the repair, GO to T2 .

No
GO to T2 .
  T2 REPEAT THE DDM SELF-TEST  
  • Ignition ON.
  • Using a scan tool, clear the DTCs and repeat the DDM self-test.

No
The system is operating correctly at this time. The circuit short has been repaired.
