System Test: PS-2

Indicates failure of wiring harness (control unit-to-ignition coil). To test, turn ignition off. Disconnect control unit connector. Start engine and operate at idle. Using a voltmeter, measure voltage between terminals "L" (Yellow/Blue wire) and "D" (Black Wire) of control unit connector. If 12 volts is present, replace control unit. If 12 volts is not present, repair wiring harness between control unit and ignition coil.
