One advantage of power assisted steering over manual steering on a light vehicle is:

• A low steering box ratio reducing the number of turns
• A high steering box ratio increasing the number of turns
• A low steering box ratio increasing the number of turns
• A high steering box ratio reducing the number of turns

When cornering a vehicle with electronically controlled air suspension will:

• Increase pressure to the inner spring immediately
• Decrease pressure to the inner spring immediately
• Increase pressure to the inner spring after a short delay
• Increase pressure to the outer spring after a short delay

How would the thrust angle be set on a light vehicle?

• Gauges on rear wheels, adjusting parallel to the centre line
• Gauges on same side adjusting parallel to centre line
• Gauges on front wheels adjusting equal from front of vehicle
• Gauges on front wheels adjusting parallel to centre line

A coil Spring is subjected to three forces during normal operation. These forces are:

• Compressive, tensile and torsional
• Shear, bending and compressive
• Tensile, compressive and shear
• Compressive, shear and torsional

A test on an ABS wheel sensor is open circuit. An acceptable repair would be to:

• Replace the sensor and wiring back to the nearest connector
• Cut out damaged section of wiring and splice in new section
• Replace wiring nearest connector sensor,splicing at sensor
• Replace both sensors on same axle as the supplied in pairs

An ABS control unit calculates that a wheel is about to lock up by:

• Sensing the deceleration force of the vehicle
• Sensing a sudden drop in DC voltage from a wheel sensor
• Sensing a sudden drop in speed from vehicle tachograph
• Sensing a sudden drop in AC voltage from a wheel sensor

ABS light on round left corner. Fault code intermittent incompatible speed signal NSF sensor?

• Poor connection NSF sensor when suspension extends
• Poor connection NSF sensor each time suspension compresses
• Unequal air gaps NSF and OSF sensor causing voltage to drop
• Excessive play in front wheel bearing causing sensor to move

If the pump should fail in a hydraulic power assisted steering system:

• The mechanical steering system must still operate
• Engine will automatically go into reduced power mode
• Steering lock will engage to prevent vehicle being used
• Immobiliser will prevent vehicle being used until repair

When checking resistance in ABS modulator valve it's essential that:

• The brake Pedal is not pressed
• The wiring harness is connected to the pump
• The wiring harness is disconnected from the modulator
• The vehicle ignition is switched off

Electronic brake force distribution (EBD) when applied to a light vehicle:

• Controls brake force at rear wheels when unladen
• Controls brake force by sensing the slip ratio of tyres
• Controls brake force at wheels by measuring load of axles
• Controls brake force at wheels through road surface temp
