Power Door Lock Control Module: Testing and Inspection
TERMINALS OF ECU1. CHECK POWER WINDOW REGULATOR MASTER SWITCH ASSY (DRIVER DOOR ECU)
Terminals Of Control Module/Pinouts:
a. Disconnect the P22 switch connector.
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 switch connector and check the voltage of each terminal of the connector.
HINT: Use an oscilloscope to check the output voltages of terminal LSW.
If the result is not as specified, the switch (door ECU) may have a malfunction.
Terminals Of Control Module/Pinouts:
2. CHECK INSTRUMENT PANEL J/B ASSY (MULTIPLEX NETWORK BODY ECU)
a. Disconnect the 1A, 1D, 1F, 1J, 1M, 1O J/B, B5 and B6 ECU connectors.
b. Check the voltage and resistance of each terminal of the wire harness side connectors.
If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the J/B and ECU connectors and check the voltage of each terminal of the connectors.
If the result is not as specified, the J/B (body ECU) may have a malfunction.
3. w/ Power back door:
a. Disconnect the P13 and P14 ECU connectors.
b. Check the voltage and resistance of each terminal of the wire harness side connectors.
If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the ECU connectors and check the voltage of each terminal of the connectors.
If the result is not as specified, the ECU may have a malfunction.
