Note On Intermittents

If an intermittent Code 19 is being set, manipulate the related wiring while observing engine data parameter .1.0 at ignition on. If the failure is induced, the "battery voltage" reading will jump from its normal 0 volt reading to a reading greater than 11 volts. This will help to isolate the location of the malfunction.
