IGN TIMING TIMING N/A 20-26° 42-46° 42-46°
(1) Monitor 60-pin adapter is required for this vehicle.
(2) Referenced values shown may vary +/- 20% depending on operating conditions and other factors. RPM values are axle and tire dependent.
(3) HO2S should switch from rich (red LED) to lean (green LED), or lean to rich, at least once every 3 seconds. HO2S voltage should toggle above and below .450 DCV, but should never be a negative value.
(4) Brake pedal on.
(5) A/C on.
(6) Steering wheel turned.
(7) Monitor in DCV manual mode, reference pin to PWR GND (40/60).
(8) Low speed radiator fan on.
(9) High speed radiator fan on.
