B1567
DTC B1567
CIRCUIT DESCRIPTION
The switch that failed 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.
DTC DESCRIPTORS
This diagnostic procedure supports the following DTCs:
- DTC B1562 Mirror Right Control Switch Circuit Low
- DTC B1567 Mirror Left Control Switch Circuit Low
- DTC B1572 Mirror Up Control Switch Circuit Low
- DTC B1577 Mirror Down Control Switch Circuit Low
CONDITIONS FOR RUNNING THE DTC
The DDM must be powered for this DTC to set.
CONDITIONS FOR SETTING THE DTC
If the DDM receives the message that a mirror switch is closed for more than 30 continuous seconds, the DDM sets a DTC.
ACTION TAKEN WHEN THE DTC SETS
The DDM ignores the continuous message from the DDSA 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.
