DTC Descriptors
DTC B1697
- Mirror Left-Up Control Switch Circuit Low

DTC B1702
- Mirror Left-Down Control Switch Circuit Low

DTC B1707
- Mirror Right-Up Control Switch Circuit Low

DTC B1712

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 (Outside Mirror Description and Operation) .


Conditions for Running the DTC

Battery voltage must be between 9-16 volts.


Conditions for Setting the DTC

* The DDSA detects that the switch contacts are activated.
* Condition must be present for greater than 30 seconds.



Actions Taken When the DTC Sets

Stores DTC B1697, B1702, B1707, or B1712 in DDSA memory.


Conditions for Clearing the DTC

* The condition responsible for setting the DTC no longer exists.
* You issue a scan tool CLEAR DTCs command.



Diagnostic Aids

The following conditions may cause an intermittent malfunction:

* When a contact for a mirror position switch has failed, it will affect both mirrors.
* The DDSA is shorted internally.
