A760F AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION SYSTEM: TERMINALS OF ECM

1. CHECK ECM





HINT
The standard voltage at each ECM terminal is shown in the table below.

In the table, first follow the information under "Condition". Look under "Terminal No. (Symbol)" for the terminals to inspect. The standard voltage between the terminals is shown under "Specified Condition".

Use the illustration above as a reference for the ECM terminals.









HINT
*: Voltage is input intermittently as this is an intermittent circuit. (Voltage varies between a peak of 7.5 to 14 V and a low of 0 to 1.5 V.)

(a) Using an oscilloscope, check waveform 1.









(b) Using an oscilloscope, check waveform 2.









(c) Using an oscilloscope, check waveform 3.









(d) Using an oscilloscope, check waveform 4.









(e) Using an oscilloscope, check waveform 5.









(f) Using an oscilloscope, check waveform 6.









(g) Using an oscilloscope, check waveform 7.









(h) Using an oscilloscope, check waveform 8.
