PARASITIC DRAW TEST
This test will locate circuits with current when the vehicle is turned off.
Note: It is normal for some vehicle modules to continue to draw current for 20
minutes after the vehicle is turned off before the module shuts down.
Some vehicles will power up modules if the key FOB is within 20 feet of the
vehicle. Store the key FOB well away from the vehicle when performing a parasitic
test.
Turn the unit ON
Touch the probes to the terminals of
each fuse in the fuse panel until you find
those that are flowing current.
An inactive circuit (no current flow) will
beep once and display (0 0 0)
An active circuit ( current is flowing) will
beep 3 times and display an approximate
amperage value.
An open or blown fuse will not beep and
will display (- - -)
Use the AMPERAGE MEASUREMENT
MODE to accurately read the amperage
in the active circuit.
Compare actual amperage reading to
vehicle specifications.
