B1616

CIRCUIT DESCRIPTION
The mirror horizontal and vertical position sensors are potentiometers. The Memory Mirror Module (MMM) provides these sensors with a 5 volt reference circuit and a low reference circuit. The MMM monitors the horizontal and vertical position sensor signal circuits which change values based on mirror position. These voltage values are used to determine mirror position and can be set into memory. When the MMM receives a memory recall request, the MMM will control the power mirror to the memory position based on the horizontal and vertical position sensor signal values.

CONDITIONS FOR RUNNING THE DTC
Battery voltage must between 9.0-16.0 volts.

CONDITIONS FOR SETTING THE DTC
The horizontal and/or vertical position sensor signal(s) are greater than 4.75 volts or less than 0.50 volts.

ACTION TAKEN WHEN THE DTC SETS
Memory movements on the malfunctioning axis are disabled.

CONDITIONS FOR CLEARING THE DTC
When the fault is no longer present, the MMM changes the current DTC to a history DTC. The MMM will clear the history DTC after 50 fault free ignition cycles.

DIAGNOSTIC AIDS
^ If DTC B1586 is set by itself, the left horizontal position sensor signal circuit maybe open, shorted to ground or battery
^ If DTC B1596 is set by itself, the left vertical position sensor signal circuit maybe open, shorted to ground or battery
^ If DTC B1616 is set by itself, the right horizontal position sensor signal circuit maybe open, shorted to ground or battery
^ If DTC B1626 is set by itself, the right vertical position sensor signal circuit maybe open, shorted to ground or battery.
^ If DTCs B1586 and B1596 are both set, the left 5 volt reference or low reference circuit(s) maybe open, shorted to ground or battery.
^ If DTCs B1616 and B1626 are both set, the right 5 volt reference or low reference circuit(s) maybe open, shorted to ground or battery.
