Pinpoint Test E: DTC B106E

Driver Seat Module (DSM)

Pinpoint Tests

Pinpoint Test E: DTC B106E

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 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. 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 will be set with DTC B106E. When DTC B106F is present, the DSM 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



PINPOINT TEST E: DTC B106E

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

-------------------------------------------------
E1 REVIEW THE DTCs


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

Yes
INSTALL a new DSM. REFER to Driver Seat Module (DSM) 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 Diagnostic Trouble Code (DTC) Chart Diagnostic Trouble Code (DTC) Chart. After the repair, GO to E2.

-------------------------------------------------
E2 CARRY OUT THE DSM SELF-TEST


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

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