B1575

CIRCUIT DESCRIPTION
The outside rear view mirror switch supplies power and ground inputs to the memory seat module (MSM) for use in driving the driver and passenger outside rearview mirror horizontal and vertical motors. When the MSM recognizes the input combination, it moves the appropriate mirror motor in the requested direction. If the MSM sees the input combination for greater than 30 seconds, a DTC B1560, B1565, B1570 or B1575 is set and the mirror outputs are disabled.

CONDITIONS FOR RUNNING THE DTCs
Battery input voltage between 9.0 and 16.0 volts.

CONDITIONS FOR SETTING THE DTCs
Mirror switch inputs to the MSM are active for greater than 30 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ Mirror outputs are disabled.
^ Memory recall commands are ignored.

CONDITIONS FOR CLEARING THE DTC
^ The MSM no longer detects the switch failure for greater than 30 seconds.
^ DTC will clear after 50 consecutive ignition cycles.

DIAGNOSTIC AIDS
^ The following conditions may cause an intermittent malfunction:
- An outside rear view mirror switch that is sticking.
- An outside rear view mirror switch that was pressed for longer than 30 seconds.
^ If the DTC does not reset after it has been cleared, then the malfunction may be intermittent. Refer to Testing for Intermittent and Poor Connections in Diagnostic Aids.
