Test 8, Isolate EDIS Module/Pip Fault

With key off, connect EDIS diagnostic cable positive lead to battery positive. Set DVOM to 20-volt AC scale. Hold EDIS diagnostic cable PIP push button down. Crank engine, and measure voltage breakout box pins No. J43 (PIP E) and J7 (BAT -).

If settled AC voltage is greater than one volt, go to next test. If settled AC voltage is less than one volt, there is no PIP output from EDIS module. Replace EDIS module, and remove all test equipment. Reconnect all components, and check for fault codes.
