Test Equipment Hook-Up

  1. Turn ignition off. Disconnect harness from Electronic Control Unit (ECU). Connect test equipment to vehicle. See Fig 1. The hose length between the vacuum gauge and the test setup is critical. Hose length must be 3' minimum, 4' maximum, and 5/32" inside diameter.
  2. Set DVOM to "BATTERY TEST". Verify that battery exceeds minimum voltage stated on tester label. When using DVOM in "TESTER" position, test leads must be removed from DVOM test jacks for proper operation.
