Pinout Values and Diagnostic Parameters

TERMINALS OF ECU
1. CHECK ECM

(a) Measure the voltage of the ECM connector.

HINT:
Each ECM terminal's standard voltage is shown in the table.
In the table, first follow the information under "Condition". Look under "Symbols (Terminal No.)" 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.

Part 1:

Part 2:

Waveform 1:

(b) Using an oscilloscope, check the waveform 1.

Waveform 2:

Waveform 3:

(d) Using an oscilloscope, check the waveform 3.

Waveform 4:

(e) Using an oscilloscope, check the waveform 4.

Waveform 5:

(f) Using an oscilloscope, check the waveform 5.

Waveform 6:

(g) Using an oscilloscope, check the waveform 6.

2. CHECK PASSENGER SIDE JUNCTION BLOCK (PASSENGER SIDE JUNCTION BLOCK ECU)

(a) Measure the voltage of the ECU connector.

HINT:
Each ECU terminal's standard voltage is shown in the table.
In the table, first follow the information under "Condition". Look under "Symbols (Terminal No.)" for the terminals to inspected. The standard voltage between the terminals is shown under "Specified Condition".
Use the illustration above as a reference for the ECU 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.)
