Output Devices -- Outline

[Output Device]
Fuel Injector
- If the circuit is open, the fuel injector will not operate, causing rough idle and misfiring.
- If the circuit is shorted, the fuel injector will inject fuel constantly, will not start or hard start.

IGT Signal (Ignition Control Module)
- If no IGT signals are input to the ignition control module because of an open or short circuit, the engine will not start.

Idle Air Control Valve (BAC Valve)
- If the solenoid valve or circuit has an open or short, diagnostic trouble code No.P0505 is output.
- If the circuit is open, the idle air control valve will be fully closed, causing rough idle, engine stalling, and acceleration hesitation when cold.
- If the circuit is shorted, the idle air control valve will be fully opened and the idle speed will be increased, causing hunting.

Fuel Pump Relay
- If the circuit is open, the engine will not start.
- If the circuit is shorted, the fuel pump will operate whenever the ignition switch is ON.

Purge Solenoid Valve
- If the solenoid valve or circuit has an open or short, diagnostic trouble code No.P0443 is output.
- If the circuit is open, no symptom will be noticed.
- If the circuit is shorted, the engine stalls at low speed.
- A short circuit may cause an improper air/fuel ratio, causing rough idle and hard starting.

VRIS Solenoid Valve No.1
- If the solenoid valve or circuit has an open or short, diagnostic trouble code No.P1521 is output.
- If the circuit is open, the solenoid valve will stay OFF and the shutter valves will stay closed, causing a poor acceleration or lack of power.
- If the circuit is shorted, the solenoid valve will stay ON and the shutter valves will stay open, causing a poor acceleration or lack of power.

VRIS Solenoid Valve No.2
- If the solenoid valve or circuit has an open or short, Diagnostic trouble code No.P1522 is output.
- If the circuit is open, the solenoid valve will stay OFF and the shutter valves will stay closed, causing a poor acceleration or lack of power.
- If the circuit is shorted, the solenoid valve will stay ON and the shutter valves will stay open, causing a poor acceleration or tack of power.

NC Signal (NC Relay)
- If the circuit is open, the air conditioner will not operate.
- If the circuit is shorted, the air conditioner will constantly operate when the ignition switch is ON.

Torque Reduction Inhibit Signal (ABS/TCS Control Unit)
- If the circuit open or short, Diagnostic trouble code No.P4627 is output.
If the circuit is open or shorted, the traction control wilt not operate.

EGR Solenoid Valve (Vent)
- If the circuit is open or shorted, no symptom will be noticed.

EGR Solenoid Valve (Vacuum)
- If the circuit is shorted, causing rough idle, engine stall.

PRC Solenoid Valve
- If the circuit is shorted, no symptom will be noticed.
- If the circuit is open, the engine will be hard to start when hot.

Condenser Fan Relay No.1
- If the circuit is shorted, the condenser fan and cooling fan will always operate while the ignition switch is ON.
- If the circuit is open, the condenser fan will not operate.

Condenser Fan Relay No.2 and Cooling Fan Relay
- If the circuit is shorted, the cooling fan will always operate while the ignition switch is ON. If the circuit is open, the cooling fan will not operate.
