Ignition Coil Power Transistor Continuity Check< 3.0L Engine >

NOTE: An analog-type ohmmeter should be used.
NOTE: Connect the negative probe of the ohmmeter to terminal 2.
CAUTION: This test must be performed quickly (in less than 10 seconds) to prevent coil from burning and ignition power transistor from breaking.

As described in the chart below, perform a continuity check on the ignition coil power transistor.

Replace the ignition power transistor if there is a malfunction.
