B1583
CIRCUIT DESCRIPTIONThe mirror position sensors are potentiometers powered by the door module for the mirror. The driver door module (DDM), and the passenger door module (PDM) determine the horizontal and vertical position of their respective mirrors based on the signal voltages from the mirror position sensors. Each mirror has a vertical position sensor and a horizontal position sensor.
CONDITIONS FOR RUNNING THE DTC
The DDM and the PDM must be powered, in communications with each other, and can not have B1327 or B1328 set.
CONDITIONS FOR SETTING THE DTC
These DTCs will set if:
^ A mirror position sensor signal voltage is below 0.25 V for 2 seconds.
^ A mirror position sensor signal voltage is above 4.75 V for 2 seconds.
ACTION TAKEN WHEN THE DTC SETS
Memory movements are disabled. Manual movements are not disabled.
CONDITIONS FOR CLEARING THE DTC
The current DTC clears when the door module no longer senses the failure. The DTC is stored as a history DTC. The history DTC will clear either after 50 OFF/ON ignition cycles without a repeated failure or in response to a scan tool command.
