AA80F AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM: TERMINALS OF ECU

1. TCM





HINT
The standard voltage of each TCM 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 be inspected. The standard voltage between the terminals is shown under "Specified Condition".

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









(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.









(i) Using an oscilloscope, check waveform 9.









(j) Using an oscilloscope, check waveform 10.









(k) Using an oscilloscope, check waveform 11.

2. ECM





HINT
The standard voltage of 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 be inspected. The standard voltage between the terminals is shown under "Specified Condition".

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