TERMINALS OF ECUTerminals Of Control Module/Pinouts:
1. CHECK INSTRUMENT PANEL J/B ASSY (MULTIPLEX NETWORK BODY ECU)
a. Disconnect the B4, B5 and B6 ECU connectors.
b. Disconnect the 1A, 1D, 1F, 1M and 1O J/B connectors.
c. Check the voltage and resistance between each terminal of the wire harness side connectors and body.
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, 1M and 1O J/B connectors.
