Diagnostic Overview

B106E, B106F

The DSM (Driver Seat Module) controls the output to the exterior mirrors using solid state drivers. A DTC (Diagnostic Trouble Code) sets when an overload occurs on any of these drivers. The DSM (Driver Seat Module) tracks the number of repetitive faults on each circuit. The DSM (Driver Seat Module) compares the number of overloads to 3 progressive thresholds established for each circuit. If the 3 thresholds have not been exceeded, then the DTC (Diagnostic Trouble Code) of the affected circuit can be cleared by eliminating the fault, then clearing the DTCs (Diagnostic Trouble Codes) and running the self-test. At the point that each of the first 2 thresholds are exceeded, DTC (Diagnostic Trouble Code) B106E sets along with the DTC (Diagnostic Trouble Code) relating to the affected circuit. Once the final threshold has been exceeded, the affected output is permanently disabled and DTC (Diagnostic Trouble Code) B106F sets along with DTC (Diagnostic Trouble Code) B1342, at which time the DSM (Driver Seat Module) must be replaced.

DTC Fault Trigger Conditions






Pinpoint Test

1. REVIEW THE DTCs (Diagnostic Trouble Codes)

1. Review the DTCs (Diagnostic Trouble Codes) from the DSM (Driver Seat Module) self-test.

Are DTCs (Diagnostic Trouble Codes) B106F and B1342 present?








2. REPAIR OTHER DTCs (Diagnostic Trouble Codes)

1. Repair the cause of any DTCs (Diagnostic Trouble Codes) present, other than DTC (Diagnostic Trouble Code) B106E. REFER to DTC Chart: Driver Seat Module (DSM) DTC Chart: Driver Seat Module (DSM).

2. Clear the DTCs (Diagnostic Trouble Codes).

3. Using a scan tool, perform the DSM (Driver Seat Module) self-test.

Is DTC (Diagnostic Trouble Code) B106E still present?
