B1610

DTC B1580, B1590, B1610, or B1620

CIRCUIT DESCRIPTION
The mirror horizontal and vertical position sensors are potentiometers. The driver door module (DDM) and passenger door module (PDM) provide these sensors with a 5-volt reference circuit and a low reference circuit. The DDM/PDM 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 DDM/PDM receives a memory recall request, the DDM/PDM will control the power mirror to the memory position based on the horizontal and vertical position sensor signal values.

DTC DESCRIPTORS
This diagnostic procedure supports the following DTCs:
- DTC B1580 Left Front Mirror Horizontal Position Sensor Circuit
- DTC B1590 Left Front Mirror Vertical Position Sensor Circuit
- DTC B1610 Right Front Mirror Horizontal Position Sensor Circuit
- DTC B1620 Right Front Mirror Vertical Position Sensor Circuit

CONDITIONS FOR RUNNING THE DTC
Battery voltage must between 9-16 volts.

CONDITIONS FOR SETTING THE DTC
The horizontal and/or vertical position sensor signals are greater than 4.75 volts or less than 0.50 volt.

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 DDM/PDM changes the current DTC to a history DTC. The DDM/PDM will clear the history DTC after 50 fault-free ignition cycles.

DIAGNOSTIC AIDS
- If DTC B1580 is set by itself, the left horizontal position sensor signal circuit may be open, shorted to ground or battery
- If DTC B1590 is set by itself, the left vertical position sensor signal circuit may be open, shorted to ground or battery
- If DTC B1610 is set by itself, the right horizontal position sensor signal circuit may be open, shorted to ground or battery
- If DTC B1620 is set by itself, the right vertical position sensor signal circuit may be open, shorted to ground or battery.
- If DTCs B1580 and B1590 are both set, the left 5-volt reference or low reference circuits may be open, shorted to ground or battery.
- If DTCs B1610 and B1620 are both set, the right 5-volt reference or low reference circuits may be open, shorted to ground or battery.
