Test 46, Check VBAT Open To Coil

Turn key off, and connect ECA. Connect EDIS Diagnostic Cable (007-00059) to breakout box (T83L-50-EEC-IV), EDIS module and coil pack. DO NOT connect VR sensor tee. See Figure. Use EDIS No. 6 overlay. Connect EDIS diagnostic cable negative to negative battery terminal, leaving positive lead disconnected. Set EDIS diagnostic cable box switch to 4/6 CYLINDER position. Set DVOM to 20-volt scale.

Turn key on, but leave engine off. Measure voltage between breakout box pins No. (+) J5 (VBAT C) and (-) J7 (BAT -). If voltage is greater than 10.5 volts, go to next test. If voltage is less than 10.5 volts, repair open circuit. Remove all test equipment, and reconnect all components. Clear Continuous Memory, and check for fault codes.
