ECM Terminals and Reference Value
PREPARATION
1. ECM is located behind the instrument lower panel. For thisinspection, 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.
I Use extreme care not to touch 2 pins at one time.
I Data is for comparison and may not be exact.
Be sure ECM unit is properly grounded before checking.
