Circuit/System Testing
Perform the Liftgate Calibration (Except Avalanche and EXT Escalade) (See: Body and Frame/Doors, Hood and Trunk/Trunk / Liftgate/Testing
and Inspection/Programming and Relearning). The liftgate module should learn the travel limits, exit the calibration mode, and B1019 00 will
become a history code.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

DTC Descriptor
DTC B1023 00
- Integral Switch Performance
Circuit/System Description
The driver door switch (DDS) and front passenger door switch (PDS) each contain switches that control power door lock and window functions.
The DDS also contains the control switch for the power outside rear view mirrors. These switches are integrated within the door control modules
and are not serviceable as separate components. The DDS and PDS monitor these switch inputs for internal faults and set B1023 00 if any are
detected.
Conditions for Running the DTC
The system voltage is 9-16 volts.
Conditions for Setting the DTC
The DDS or PDS detects multiple or simultaneous inputs from a window or door lock switch.
Action Taken When the DTC Sets
The DDS or PDS ignores inputs from the malfunctioning switch.
Conditions for Clearing the DTC
* The DTC will be current for as long as the fault is present.
* When the fault is no longer present, the DTC will be a history DTC.
* A history DTC will clear after 50 ignition cycles.
