TEST ACTION APPLICABILITY
2 NOTE: This test must be repeated for the adjacent ignition wire.
Turn the ignition off.
Disconnect the ignition wire from the spark plug.
NOTE: Before continuing inspect the ignition wire for damage or carbon
tracking coil or the spark plug insulator boot. If a problem is found, replace
the ignition wire.
Install a spark tester to the ignition wire.
While cranking the engine observe the spark coming from the spark tester.
NOTE: A crisp blue spark that is able to jumper the gap of the spark tester
should be generated.
Is a good spark generated?
All
Yes → Ensure the cylinder is operationg properly. If OK, replace the
Spark Plug.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
No → Go To 3
3 NOTE: This test must be repeated for the adjacent ignition wire.
Turn the ignition off.
Remove the ignition wire.
Measure the resistance of the ignition wire.
Is the resistance below 10K ohms?
All
Yes → Go To 4
No → Replace the Ignition Wire.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
4 Turn the ignition off.
Disconnect the Ignition Coil harness connector.
Turn the ignition on.
With the DRBIIIt, actuate the ASD Relay.
Using a 12-volt test light connected to ground, probe the (A142) ASD Relay Output
circuit in the Ignition Coil harness connector.
Does the test light illuminate brightly?
All
Yes → Go To 5
No → Repair the (A142) ASD Relay Output circuit.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
5 Turn the ignition off.
Disconnect the Ignition Coil harness connector.
Using a 12-volt test light connected to 12-volts, probe the Ignition Coil Driver circuit.
Crank the engine for 5 second while observing the test light.
Does the test light blink/flicker?
All
Yes → Replace the Ignition Coil.
Perform POWERTRAIN VERIFICATION TEST VER-2-NGC.
No → Go To 6
