B1567
CIRCUIT DESCRIPTIONThe switch that tailed and generated this diagnostic trouble code (DTC) is part of the driver door switch assembly (DDSA). This assembly contains a microprocessor which takes the signal generated by this switch and assigns a digital message to the switch signal The DDSA then sends this message over the power door serial data link to the driver door module (DDM). The DDM then either moves the left mirror or sends commands over the power door serial data link 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 a mirror switch is closed for more than 30 continuous seconds, the driver door module sets a DTC.
ACTION TAKEN WHEN THE DTC SETS
The DDM ignores the continuous message from the driver door switch assembly for this switch. 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
When the switch message status changes, the DDM clears this current DTC and stores it as history. The history DTC will clear either after 50 OFF/ON ignition switch cycles without a repeated failure or in response to a scan tool command.
