Z31 Computer Pin Out

The Z31 had a few changes throughout the years and models of the wiring to the ECU. Here we will try to show you the differences with a Pinout Chart.

ECCS Location

The ECCS or Computer for the Z31 is located behind the passenger's kick panel. This is the small panel on the outer wall right below the glovebox. You will need to remove 2 screws to get the panel off.

There are three connectors that plug into the ECCM. These connections can sometimes corrode and cause Driveability issues. Cleaning these will resolve some problems but sometimes for Diagnostic procedures you will need to check the pinout on sensors. The diagram below will show you what each pin connects to.
