ECM Terminals and Reference ValueNCEC0044PREPARATIONNCEC0044S011. ECM is located behind the center console. For this inspection:
Remove the front passenger center console panel.
2. Remove ECM harness protector.
3. Perform all voltage measurements with the connector con-
nected. Extend tester probe as shown to perform tests easily.
IOpen harness securing clip to make testing easier.
IUse extreme care not to touch 2 pins at one time.
IData is for comparison and may not be exact.
ECM HARNESS CONNECTOR TERMINAL LAYOUTNCEC0044S02
ECM INSPECTION TABLENCEC0044S03Specification data are reference values and are measured between
each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the ECM's
transistor. Use a ground other than ECM terminals, such as
the ground.
