Pinpoint Test AA: DTCs B106E, B106F

Normal Operation

When a repetitive fault causing a circuit overload is detected on certain output circuits, the Driver Door Module (DDM) disables the circuit by removing voltage, or ground, to the affected circuit. The circuit remains disabled until the fault is corrected and an on-demand self-test is run. When the on-demand self-test has been run after all faults have been corrected, any DTCs related to the fault are cleared.

- DTC B106E (Solid State Driver Disabled Due to Short Circuit) - a continuous DTC that sets when the DDM has disabled a circuit due to a repetitive fault causing a circuit overload. For a complete list of corresponding DTCs, refer to Principles of Operation.
- DTC B106F (Module Disabled Due to External Fault) - a continuous DTC that sets when one or more output functions are permanently disabled due to a repetitive circuit overload fault. DTC B106F is set with DTC B106E. When DTC B106F is present, the DDM must be replaced after the fault condition has been corrected. Principles of Operation

This pinpoint test is intended to diagnose the following:

- Output circuit short to ground or voltage
- DDM


PINPOINT TEST AA: DTCs B106E, B106F

NOTICE: If DTC B106F is present and the DDM is to be replaced, the fault condition must be corrected first. Failure to correct the fault condition first may cause damage to the new DDM, resulting in a repeat repair.

-------------------------------------------------
AA1 REVIEW THE DTCs

- Review the DTCs from the DDM self-test.
- Is only DTC B106F present?

Yes
INSTALL a new DDM. REFER to Driver Door Module (DDM) Service and Repair. TEST the system for normal operation.

No
CORRECT any DTCs present other than DTC B106E (DTC B106F may also be present). REFER to DTC Charts. After the repair, GO to AA2. [1][2]Diagnostic Trouble Code Descriptions

-------------------------------------------------
AA2 CARRY OUT THE DDM SELF-TEST

- Carry out the DDM self-test.
- Is only DTC B106F present?

Yes
INSTALL a new DDM. REFER to Driver Door Module (DDM) Service and Repair. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern was caused by a fault in one of the output circuits, which is no longer present.
