AA80E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION SYSTEM: TERMINALS OF ECU

1. TCM

HINT
Each TCM terminal standard voltage 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.

Reference

(b) Using an oscilloscope, check waveform 2.

Reference

(d) Using an oscilloscope, check waveform 4.

Reference

(e) Using an oscilloscope, check waveform 5.

Reference

(f) Using an oscilloscope, check waveform 6.

Reference

(g) Using an oscilloscope, check waveform 7.

2. ECM

HINT
Each ECM terminal standard voltage 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.

3. Cowl Side Junction Block ECU (Main Body ECU)

HINT
Each ECU terminal standard voltage is shown in the table below.

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

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

HINT
*1: 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 to1.5 V.)
