SHIFT LOCK HARNESS CONNECTOR TERMINALS LAYOUT

SHIFT LOCK CONTROL UNIT INSPECTION TABLE

Shift lock control unit terminal data are reference values, measured between each terminal and ground.

NOTE:
Take care that the pointer swings only momentarily because the output time is so short. If the inspection is done with an oscilloscope, it
should be observed that the power source voltage lasts for 3.5 to 10 ms.
