CIRCUIT DESCRIPTION
The switch that failed and generated this diagnostic trouble code (DTC) is pan of the driver door switch assembly. This module contains a microprocessor which takes the ground signal generated by this switch and assigns a digital message to the switch signal. The driver door switch assembly then sends this message over a simple bus interface (SBI) link to the driver door module (DDM).
CONDITIONS FOR RUNNING THE DTC
The DDM must be powered and must not have DTCs B1327-Battery Low Voltage or B1328-Battery High Voltage set for this DTC to set.
CONDITIONS FOR SETTING THE DTC
If the driver door module (DDM) receives the message that the circuit is closed for more than 15 continuous seconds the DDM sets this DTC.
ACTION TAKEN WHEN THE DTC SETS
Once the DTC is set, the DDM ignores all down commands but enables all up commands from the switch setting this DTC. The window still operates from the passenger door switch.
CONDITIONS FOR CLEARING THE DTC
The DDM clears this DTC when the switch signal is not received.
TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table.
2. Checks the existing state of the driver door window switch module right front passenger window switch by using the current state of the input parameter.
