This test procedure requires that the vehicle battery has passed a load test and is completely charged.
There is an adequate supply of fuel in the fuel tank.
When disconnecting electrical connectors or removing fuses and relays from a fuse block, always inspect both mating electrical terminals for corrosion and terminal tightness.
Use the J 35616 for any test that requires probing the underhood fuse block terminals, component wire harness terminals, or the ECM wire harness terminals. See Special Tools .
