Pinout Values and Diagnostic Parameters
TERMINALS OF ECU1. CHECK POWER WINDOW REGULATOR MASTER SWITCH
Terminals Of ECU/Pinouts:
a. Disconnect the P17 switch connector.
b. Measure the voltage and resistance of each terminal of the wire harness side connector.
Standard:
If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the P17 switch connector.
d. Reset the power window motor.
e. Measure the voltage of each terminal of the connector.
Standard:
If the result is not as specified, the master switch may have a malfunction.
f. Check that the AUTO lamp illumination.
When turning the power switch ON (IG), check that the AUTO lamp illuminates (green).
2. CHECK INSTRUMENT PANEL J/B ASSEMBLY (MULTIPLEX NETWORK BODY ECU)
Terminals Of ECU/Pinouts:
a. Disconnect the 1A, 1D, 1E and 1B J/B connectors.
b. Measure the voltage and resistance between each terminal of the wire harness side connectors and body ground.
Standard:
If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the 1A, 1D, 1E and 1B J/B connectors.
d. Measure the voltage between each terminal of the connector and body ground.
Standard:
If the result is not as specified, the J/B (body ECU) may have a malfunction.
