7A2-134 TRANSMISSION CONTROL SYSTEM (JR405E)
TCM Signal Test
Inspection Tool
Use a DMM to measure voltage and circuit continuity.
Also use an oscilloscope to measure waveform. Refer
to the following table for the specified ranges or
reference waveform. Since the TCM terminals are extremely small, use
appropriate test adapter from the test adapter kit. This
will make measurement easier.
