DTC B1580

Mirror Horizontal Position Sensor Circuit

DTC B1590

Mirror Vertical Position Sensor Circuit

Circuit/System Description

The driver door module (DDM) and passenger door module (PDM) receive mirror position
signals from the mirror horizontal and vertical position sensors. These signals are used by the
door modules for memory recall functions of the driver and passenger mirrors. The door modules
command the mirror memory settings based upon the voltage level received back from the
position sensors. Each door module provides a 5 volt supply, a signal, and ground circuit for each
of the position sensors. The horizontal and vertical position sensors are variable resistors that the
door modules monitor voltage levels across. When a memory setting is recalled, the door modules
command the mirror motors in the appropriate directions until the stored position sensor voltage
levels are achieved. The DDM and PDM monitor the signal circuits to determine if the voltage
level is out of range. For more detailed information concerning power mirror operation refer to
Outside Mirror Description and Operation.
Conditions for Running the DTC

Battery voltage must be between 9-16 volts.

Conditions for Setting the DTC

These DTCs will set if:

A mirror position sensor signal voltage is below 0.5 volts for 2 seconds.

A mirror position sensor signal voltage is above 4.5 volts for 2 seconds.
Actions Taken When the DTC Sets

The door module will ignore the failed position sensor.

The door module will ignore memory set or recall for the mirrors.

Manual mirror movements will be allowed.
Conditions for Clearing the DTC

The condition responsible for setting the DTC no longer exists.

control module.
 If greater than the specified range, test the 5-volt reference circuit for a short to
voltage. If the circuit tests normal, replace the appropriate door control module.
4. Verify with a scan tool the appropriate mirror position parameter is less than 4.5 volts.
 If greater than the specified range, test the appropriate mirror position signal circuit
for a short to voltage. If the circuit tests normal, replace the appropriate door control
module.
5. Install a 3-A fused jumper wire between the appropriate mirror position signal circuit and
the 5-volt reference circuit terminal A. Verify with a scan tool the appropriate mirror
position parameter is greater than 4.5 volts.
 If less than the specified range, test the appropriate mirror position signal circuit for
short to ground or an open/high resistance. If the circuit tests normal, replace the
appropriate door control module.
6. If all circuits test normal, test or replace the appropriate mirror.

Circuit/System Description

The driver door module (DDM) and passenger door module (PDM) each provide motor control
output functions for their respective mirrors. These output controls allow each door module to
command their respective power mirrors in horizontal and vertical positions. The driver door
switch assembly (DDSA) sends a serial data message to the door modules when the mirror switch
is activated to the up, down, left or right positions. When the door modules detect an active
mirror command from the DDSA, they will command the respective mirror motor in the
appropriate direction. Each door module commands their respective mirror motors by applying a
ground or voltage to the control circuit, depending on the desired mirror position. For more
detailed information concerning power mirror operation refer to Outside Mirror Description
and Operation.
Conditions for Running the DTC

Battery voltage must be between 9-16 volts.

Circuit/System Description

The outside rearview mirror control switch is contained within the driver door switch assembly
(DDSA). The DDSA contains a microprocessor which takes the signal generated by the outside
rearview mirror control switch and assigns a digital message to the switch signal. The DDSA
sends this message via class 2 serial data to the driver door module (DDM) to move the left
mirror or the passenger door module (PDM) to move the right mirror. The DDM or PDM then
applies voltage and ground to the appropriate circuits of the appropriate mirror motor to move
the mirror vertically and/or horizontally. The mirror motors are reversible. For more detailed
information concerning outside rearview mirror operation refer to Outside Mirror Description
and Operation.

DESCRIPTION AND OPERATION

OUTSIDE MIRROR DESCRIPTION AND OPERATION

Outside Mirror System Components

Driver door module (DDM)

Passenger door module (PDM)

Driver door switch assembly (DDSA)

Driver outside rearview mirror

Passenger outside rearview mirror

DOOR CONTROLS circuit breaker (30 -Amp)

ACCA/DRIV DR SW fuse (10-Amp)
Outside Rearview Mirror Operation

The outside rearview mirrors are controlled by the driver door switch assembly (DDSA) which
contains the mirror control switches, the driver door module (DDM), and the passenger door
module (PDM). The DDSA decodes mirror control switch activations while the door modules
apply battery voltage and ground to their respective mirror motors to move the mirrors to the
desired positions.
Outside Rearview Mirror Switches

The outside rearview mirror adjustment switches are contained in the driver door switch assembly
(DDSA). The Mirror Select Switch is used to select which mirror, driver or passenger, is to be
adjusted. The Mirror Position Switch is used to move the mirror that has been selected for
adjustment to the desired position. The DDSA reports the activity of these switches to the driver
door module (DDM) and the passenger door module (PDM) via class 2 serial data circuit.

On vehicles that have the memory mirrors feature, the DDSA is also wired to, and receives direct
signal inputs from the memory function switch. For more information concerning the memory
function switch refer to Memory Seats Description and Operation .
Mirror Motors

Each mirror has 2 reversible motors for position adjustment; the vertical motor and the horizontal
motor. Each reversible motor is wired to its associated door module through 2 motor control
circuits. The door modules control the reversible motors by applying battery voltage and ground

to these 2 motor control circuits. The door module reverses the polarity of the voltage and ground
it applies to these 2 circuits in order to run the motor in opposite directions. For example, to run
the mirror in the Up direction, the door module applies voltage to the mirror motor up control
circuit, and ground to the mirror motor down control circuit. To run the mirror in the opposite
Down direction, the module reverses the polarity, supplying voltage to the down control circuit,
and ground to the up control circuit.
Memory Mirrors Operation

The memory mirrors are controlled by the mirror position sensors, the driver door switch
assembly (DDSA), the driver door module (DDM), and passenger door module (PDM). The
DDSA decodes memory switch activations while the mirror position sensors provide mirror
position information to the door modules. The door modules supply voltage and ground to the
mirror position sensors, store mirror position information, and apply voltage and ground to the
mirror motors.

For memory operations, each outside rearview mirror has four additional circuits and contains a
vertical position sensor and a horizontal position sensor. The position sensors, which are
potentiometer type sensors, are attached to the corresponding position motor of each mirror, and
provide constant information, in the form of feedback voltage to the associated door module to
indicate the vertical and horizontal position of the mirror. Each position sensor of each mirror is
wired to the corresponding front door module through four circuits to provide mirror location
information in the following manner. Each door module supplies a 5-volt reference voltage and
ground to both of its position sensors. Each door module also supplies 5 volts to the vertical
position sensor signal circuit, and 5 volts to the horizontal position sensor signal circuit of the
corresponding position sensor. When the mirror motors run, the resistance of the attached sensors
vary, which in turn, varies the feedback voltage to the door module.

When mirror positions are programmed into the personalization package, the front door modules
store the positions indicated by the feedback voltages of the position sensors. When a memory
recall is requested, the door modules compare the feedback voltages indicated by the current
mirror positions to the stored feedback voltages. The door modules then move the mirrors until
the current feedback voltages match the stored feedback voltage levels.
Heated Mirrors

The outside rearview mirrors heat during the defrost/defog cycles for the rear window. The driver
door module (DDM) and passenger door module (PDM) control the heated mirror functions. The
DDM supplies power and ground to the driver heated mirror and the PDM supplies it to the
passenger heated mirror. When the door modules receive a class 2 serial data message from the
HVAC control module indicating the rear defogger has been turned ON, both door modules will

activate the heated mirror by applying voltage to the heated mirror element feed circuit.
Mirrors - Outside Automatic Day/Night Feature

The automatic day/night feature of the driver outside rearview mirror is controlled by the inside
rearview mirror. The inside rearview mirror supplies a signal and a low reference to the driver
outside rearview mirror. The voltage on the signal circuit of the driver outside rearview mirror
varies between 0.5-1.5 volts depending on light conditions present at the inside rearview mirror.
At night, with the automatic day-night feature enabled, the driver outside rearview mirror will
automatically darken with the inside rearview mirror to reduce the glare from the headlamps from
behind. The voltage on the signal circuit of the driver outside rearview mirror will be near 1.5
volts. In daytime conditions, the mirrors are in the normal state. The voltage on the signal circuit
of the driver outside rearview mirror may be less than or near 0.5 volts. Refer to Automatic
Day-Night Mirror Description and Operation for further description and operation of the
inside rearview mirror.

AUTOMATIC DAY-NIGHT MIRROR DESCRIPTION AND OPERATION

Inside Rearview Mirror with Automatic Day-Night System Operation

The inside rearview mirror consist of 2 photocell sensors. The headlight sensor, located on the
front of the mirror is used to determine light conditions present at the mirror face from sources
behind the vehicle. The ambient light sensor, located on the rear of the mirror is used to
determine exterior light conditions present at the mirror. At night, with the automatic day-night
feature enabled, the inside rearview mirror will automatically darken to reduce glare from
headlamps behind the vehicle.

In daytime conditions, the mirror operates at a normal, clear state due to the high exterior light
conditions that are indicated by the ambient light sensor. When the vehicles gear selector is
placed in the REVERSE position, backup lamp voltage is supplied as an input to the inside
rearview mirror. In night time conditions only, the inside rearview mirror monitors the backup
lamp voltage to disable the automatic day-night feature. This allows the inside rearview mirror
face to gradually change to a normal, clear state and allow the driver to see objects in the mirror
clearly when backing up.
Driver Outside Rearview Mirror with Automatic Day-Night System Operation

The automatic day-night feature of the driver outside rearview mirror is controlled by the inside
rearview mirror. The inside rearview mirror supplies a signal and low reference to the driver
outside rearview mirror. At night, with the automatic day-night feature enabled, the driver outside
rearview mirror will automatically darken with the inside rearview mirror to reduce glare from
headlamps behind the vehicle. Refer to Outside Mirror Description and Operation for further
