B1023
DTC B1023
CIRCUIT DESCRIPTION
The switch that failed and generated this diagnostic trouble code (DTC) is part of the driver door module (DDM) or the passenger door module (PDM). When a switch is activated, the DDM/PDM then either actuates the appropriate component or sends a message over the serial data link to the appropriate module to actuate the appropriate component.
DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC B1023 Integral Switch Performance
CONDITIONS FOR RUNNING THE DTC
- System voltage is between 9-16 volts.
- Ignition switch is in the ON position.
CONDITIONS FOR SETTING THE DTC
If the DDM or the PDM receives multiple inputs from a single switch at the same time for more then 160 milliseconds, the DDM/PDM sets the DTC. The following switches will set this DTC:
- The door lock switch
- The power window switch
- The window lockout switch
- The mirror select switch
ACTION TAKEN WHEN THE DTC SETS
The DDM/PDM ignores the continuous inputs from the switch. The DDM/PDM will not respond to the invalid inputs as a command for the component. The DDM/PDM will respond to all other valid switch inputs.
CONDITIONS FOR CLEARING THE DTC
When the switch input status changes, the DDM/PDM clears this current DTC and stores the DTC as a history DTC. The history DTC will clear either after 50 ignition switch cycles without a repeated failure or in response to a scan tool command.
