CIRCUIT DESCRIPTION
The switch that failed and generated this diagnostic trouble code (DTC) is part of the driver door switch assembly. This assembly contains a microprocessor which takes the 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). The DDM then either moves the left mirror or sends commands over the SBI to the right front door module to move the right mirror.

CONDITIONS FOR RUNNING THE DTC
The DDM must be powered for this DTC to set.

CONDITIONS FOR SETTING THE DTC
If the driver door module receives the message that the switch is closed for more than 30 continuous seconds, the driver door module sets this DTC.

ACTION TAKEN WHEN THE DTC SETS
The DDM ignores the continuous message from the driver door switch assembly for this switch, rules it invalid, and will not respond to it. The DDM will not respond to the invalid mirror switch message as a command for either door mirror. The DDM will respond to all other valid switch messages.

CONDITIONS FOR CLEARING THE DTC
The DDM clears this DTC when the switch message status changes.
