LV08 vehicle chassis systems

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
