ECM Terminals and Reference Value
PREPARATION
1. ECM is located behind the instrument lower panel. For this
inspection, remove the driver's side instrument lower cover.
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.
Be sure ECM unit is properly grounded before checking.

Remarks: Specification 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 damage the
