DTC Descriptor
DTC B1715 02: Mirror Power Fold Control Switch Circuit Short to GroundCircuit/System Description
The DDSA has an additional power folding mirror switch built into it and each mirror contains an additional power folding mirror motor. When the switch is activated to fold mirrors, the switch contacts close, the DDSA interprets the signal input, and sends the command on to the DDM and PDM. The DDM and PDM each apply battery voltage and ground to the appropriate circuits of their respective power folding motor in order to retract the mirrors. When the switch is activated to unfold the mirrors, the door modules reverse the polarity of the voltage and ground applied to the reversible folding motors to move both mirrors to the fully extended position.
Conditions for Running the DTC
Battery voltage must be between 9-16 volts.
Conditions for Setting the DTC
A power mirror fold or retract switch input to the DDSA is active for more than 30 seconds.
Action Taken When the DTC Sets
Power folding mirror operations are suspended as long as the fault is present.
Conditions for Clearing the DTC
| • | A current DTC will clear when the fault is no longer present. |
| • | A history DTC will clear after 40 fault-free ignition cycles. |
