37. Adjustment of SWm and SWg
Time lag sequence of SWm and SWg
To check the time lag, an oscilloscope is necessary.
The time lag is determined by the variation in voltage when
SWm and SWg turn "ON" and "OFF".
Here is one example for time lag check with a single-trace oscilloscope.
Adapter should be made as shown below.
Adapter is connected to mirror housing connector and oscilloscope.
After charging the mirror housing and releasing it to put the mirror in
the "up" state, time lag appears on the oscilloscope screen.
The adjustment procedures can be referred to in item 36.
