Pinout Values and Diagnostic Parameters
TERMINALS OF ECUTerminals Of ECU:
1. CHECK POWER WINDOW REGULATOR MASTER SWITCH (DRIVER DOOR ECU)
a. Disconnect the P22 switch connector.
Pinouts:
b. Check the voltage and resistance of each terminal of the wire harness side connector.
If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the P22 switch connector and reset the power window motor (Refer to the pre-check, step 16).
Pinouts:
d. Check the voltage of each terminal of the connector.
If the result is not as specified, the master switch (door ECU) may have a malfunction.
Terminals Of ECU:
2. CHECK POWER WINDOW REGULATOR SWITCH (PASSENGER DOOR ECU)
a. Disconnect the P19 switch connector.
Pinouts:
b. Check the voltage and resistance of each terminal of the wire harness side connector.
If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the P19 switch connector and reset the power window motor (Refer to the pre-check, step 16).
Pinouts:
d. Check the voltage of each terminal of the connector.
If the result is not as specified, the regulator switch (door ECU) may have a malfunction.
Terminals Of ECU:
3. CHECK POWER WINDOW REGULATOR SWITCH (REAR LH DOOR ECU)
a. Disconnect the P20 switch connector.
Pinouts:
b. Check the voltage and resistance of each terminal of the wire harness side connector.
c. Reconnect the P20 switch connector and reset the power window motor (Refer to the pre-check, step 16).
Pinouts:

c. Reconnect the P21 switch connector and reset the power window motor (Refer to the pre-check, step 16).
Pinouts Part 1:
Pinouts Part 2:
d. Check the voltage of each terminal of the connector.
If the result is not as specified, the regulator switch (door ECU) may have a malfunction.
Terminals Of ECU:
5. CHECK INSTRUMENT PANEL J/B ASSEMBLY (MULTIPLEX NETWORK BODY ECU)
a. Disconnect the B4, B5 and B6 ECU connectors.
b. Disconnect the 1A, 1D, 1F and 1M J/B connectors.
c. Check the voltage and resistance between each terminal of the wire harness side connectors and body ground.
If the result is not as specified, there may be a malfunction on the wire harness side.
d. Reconnect the B4, B5 and B6 ECU connectors.
e. Reconnect the 1A, 1D, 1F and 1M J/B connectors.
f. Check the voltage between each terminal of the connector and the body ground.
If the result is not as specified, the J/B assembly (body ECU) may have a malfunction.
