Activation Activation applies to Description Use
AC Relay

Ignition on or control module in afterrun

Processor control of the final stage that grounds the circuit.

Checking the control module output, the electric circuit and the actuator function. When the output is active, the solenoid clutch should engage. Otherwise, use a test lamp to locate the defective lead/component.

The refrigerant circuit must also be OK.

Fuel Cut

Engine running

Processor control of final stage that activates the Shut Off solenoid valve,

Note that the diagnostic trouble code is generated when this function is activated with the diagnostic tool.

Glow Request

Ignition on or control module in afterrun

Processor control of the final stage that activates the glow function in EDC.

Can be used to activate the glow plug control module during fault diagnosis. Check the system voltage while activating to make sure the glow plugs are really working.

Swirl Control Valve

Ignition on or control module in afterrun

Processor control of the final stage that grounds the circuit.

140 Hz

65% PWM = max. activation

The control valve should govern the swirl throttle when the engine is idling. If this is not the case, check the vacuum hoses and whether the other vacuum-controlled functions can be controlled. If not, check the function of the vacuum pump.

EGR Control Valve

Ignition on or control module in afterrun

Processor control of the final stage that grounds the circuit.

140 Hz

65% PWM = max. activation

The control valve should govern the EGR valve when the engine is idling. If this is not the case, check the vacuum hoses and whether the other vacuum-controlled functions can be controlled. If not, check the function of the vacuum pump.

Charge Air Control Valve

Ignition on or control module in afterrun

Processor control of the final stage that grounds the circuit.

140 Hz

65% PWM = max. activation

The control valve should govern the wastegate rod when the engine is idling. If this is not the case, check the vacuum hoses and whether the other vacuum-controlled functions can be controlled. If not, check the function of the vacuum pump.

Idle Speed

Engine running

A temporarily revised desired value for idle speed control

Can be used to run the engine at any speed to detect noise, etc.
