- Ignition OFF, disconnect the VLOM harness connector at the VLOM assembly.
- Connect the cable that is labeled resistance from the displacement on demand (DoD) tester to the VLOM connector.
- Connect the power leads from the DoD tester to B+ and ground. Test for 11-18 ohms on each VLOM solenoid.
- If the resistance is not within the specified range for each solenoid, replace the VLOM assembly.
- Test for infinite resistance between each VLOM circuit terminal and the VLOM housing.
- If less than infinite resistance, replace the VLOM assembly.
