⁽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⁾	HEGO should switch from rich (red LED) to lean (green LED), or lean to rich, at least once every 3 seconds. HEGO 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).
