Ignition Impulse

  1. With ignition off, disconnect ECU connector. Connect a voltmeter to harness connector terminal No. 1. Turn ignition on. On non-turbo models, voltmeter should read 12 volts. If not, check for 12 volts at negative terminal of ignition coil.
  2. On Turbo models, remove distributor cap and line any slot in Hall Effect rotor with front of signal generator. Turn ignition on. Voltmeter should read less than one volt. Place a .02" (.50 mm) feeler between rotor slot and signal generator. Voltmeter should now read 8 volts. If voltage reads are not found, check wiring continuity or ignition system.
