PREPARATION
1. ECM is located behind the instrument lower cover. For this inspection:
- Remove instrument lower cover.
2. Remove ECM harness protector.
3. Perform all voltage measurements with the connector connected. Extend tester probe as shown to perform tests easily.
- Open harness securing clip to make testing easier.
- Use extreme care not to touch 2 pins at one time.
- Data is for comparison and may not be exact.
