Pinpoint Test BE: DTCs B106E, B106F

Normal Operation

When a repetitive fault causing a circuit overload is detected on certain output circuits, the Driver Seat Module (DSM) 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 DSM (Driver Seat Module) has disabled a circuit due to a repetitive fault causing a circuit overload.

- 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 sets with DTC B106E. When DTC B106F is present, the DSM (Driver Seat Module) must be replaced after the fault condition has been corrected.

This pinpoint test is intended to diagnose the following:

- Output circuit short to ground or voltage

- DSM (Driver Seat Module)

PINPOINT TEST BE : DTCs B106E, B106F

NOTICE: If DTC B106F is present and the Driver Seat Module (DSM) is being replaced, the fault condition must be corrected first. Failure to correct the fault condition first may cause damage to the new DSM (Driver Seat Module), resulting in a repeat repair.

BE REVIEW THE DTCs

- Review the DTCs from the DSM (Driver Seat Module) self-test.

Is only DTC B106F present?

Yes
INSTALL a new DSM (Driver Seat Module). REFER to Driver Seat Module (DSM) . TEST the system for normal operation.

No
CORRECT any DTCs present other than DTC B106E (DTC B106F may also be present). REFER to DTC Chart. After the repair, GO to BE2. Seats

BE2 CARRY OUT THE DSM (Driver Seat Module) SELF-TEST

- Carry out the DSM (Driver Seat Module) self-test.

Is only DTC B106F present?

Yes
INSTALL a new DSM (Driver Seat Module). REFER to Driver Seat Module (DSM) . 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.
