Output Devices

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, and the engine will not start or will start hard.

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 idle air control valve or circuit has an open or short, Diagnostic Trouble Code No.34 is output.
^ If the circuit is open, the idle air control valve will be closed throttle position, causing rough idle, engine stalling, and acceleration hesitation when cold.
^ If the circuit is shorted, the idle air control valve will be wide opened throttle 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.26 is output.
^ If the circuit is open, no symptom will be noticed.
^ If the circuit is shorted, the engine will stall 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.41 is output.
^ If the circuit is open, the solenoid valve will stay OFF and the shutter valves will stay closed, causing a power drop.
^ If the circuit is shorted, the solenoid valve will stay ON and the shutter valves will stay open, causing a power drop.

VRIS Solenoid Valve No.2
^ If the solenoid valve or circuit has an open or short, Diagnostic Trouble Code No.46 is output.
^ If the circuit is open, the solenoid valve will stay OFF and the shutter valves will stay closed, causing a power drop.
^ If the circuit is shorted, the solenoid valve will stay ON and the shutter valves will stay open, causing a power drop.

A/C Signal (A/C Relay) and Condenser Fan Low 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 blower is ON.

Torque Reduced Signal
^ If a malfunction occurs in the torque reduced signal, the torque reduction control system is inhibited and the line pressure characteristics will be high shifting. Shift shock may be slightly increased.

EGR Solenoid Valve (Vent)
^ If the solenoid valve or circuit has an open or short, Diagnostic Trouble Code No.29 is output.
^ If the circuit is open or shorted, no symptom will be noticed.

EGR Solenoid Valve (Vacuum)
^ If the solenoid valve or circuit has an open or short, Diagnostic Trouble Code No.28 is output.
^ If the circuit is shorted, the EGR control valve will remain open, causing engine stalling and hard starting.
^ If the circuit is open, no symptom will be noticed.

PRC Solenoid Valve
^ If the solenoid valve or circuit has an open or short, Diagnostic Trouble Code No.25 is output.
^ If the circuit is shorted, no symptom will be noticed.
^ If the circuit is open, the engine will be hard to start when warm.

Coolant Fan Relay No.1
^ If the circuit is shorted, the coolant fan will always operate while the ignition switch is ON.
^ If the circuit is open, the coolant fan will not operate until the engine coolant temperature exceeds 100°C {212°F}.

Coolant Fan Relay No.2 and No.3
^ If the circuit is shorted, the coolant fan will always operate while the ignition switch is ON.
^ If the circuit is open, the coolant fan will remain OFF when the engine coolant temperature exceeds 108°C {226°F}.

Condenser Fan Low Relay
^ If the circuit is shorted, the condenser fan will always operate while the ignition switch is ON.
^ If the circuit is open, the condenser fan will remain OFF when engine coolant temperature exceeds 100°C {212°F}.

Condenser Fan High Relay No.1 and No.2
^ If the circuit is shorted, the condenser fan will always operate while the ignition switch is ON.
^ If the circuit is open, the condenser fan will remain OFF when the engine coolant temperature exceeds 108°C {226°F}.
