This Sub Section applies to
all types of power/assisted steering systems. The engine must be running for this inspection.
Steering linkage
The inspection of all parts of steering linkage associated with the power steering mechanism is detailed in sub-sections 2.2B and 2.2C.
Manually switched Electronic Park Assist
designed to be activated when parking the vehicle is not a reason for rejection if the power assistance is inoperative provided the function of the steering is not adversely affected. It may be necessary to verify this by road testing
If power steering is optional fitment on the vehicle but has been disconnected in such a way that there is no adverse effect on the steering, that is not a Reason for Rejection. It may be necessary to verify this by road testing
Ensure the fluid has leaked from the power steering system and not from another source
If excessive free play is suspected at MoI 3, a further check should be made by applying manual effort to the ball-pin or ram body at right angles to the ram centre line.

Power Steering
1. With the front road wheels on the ground, vehicle in neutral gear and the parking brake applied, run the engine and rock the steering wheel in both directions. Check
a. by feel at the steering wheel, that the system is operating
b. for leaks in the system (see Information column)
c. that pipes are free from damage and are not fouling other parts of the vehicle.
2. In the case of external power systems check
a. the ram anchorages for cracks, damage and security to the frame or other fixed members of the vehicle
b. the ram for cracks and/or damage
c. for movement indicating wear at the anchorage point
3. With the engine stopped and steering wheel lightly rocked, check for excessive free play between ball-pin and valve.
4. Where practicable, check the security of the power steering pump and the condition of its drive system. |
1.
a. Power steering malfunctioning or inoperative or evidence that power assistance has been removed or disconnected when it is known that power steering is standard on the vehicle.
b. a leak in the system showing that a component, joint or seal has failed
c. a fluid pipe excessively damaged, or fouling other parts of the vehicle.
2.
a. a cracked, damaged or insecure ram anchorage
b. a cracked or damaged ram body
c. excessive free play at ram anchorage
3. Excessive free play between ball- pin and valve such that separation is likely
.
4. Pump insecure or its drive system missing or defective
