Steering control.
The law requires that vehicles are fitted with some sort of anti-theft mechanism as minimum security protection. Commonly, this is achieved by use of steering locks, transmission locks or gearshift locks. Where a steering lock mechanism is fitted as standard, testers must now check if one is present and operational.
Steering system.
Before the days of MOT Computerisation, many testers incorrectly failed steering and suspension ball joints if the dust cover was split or missing. Well, thanks to the Directive, these items will be included in the test – so if a ball joint dust cover is missing or no longer keeps the dirt out, testers will be able to correctly fail the vehicle.
Sub-section 2.2D covers the steering lock-to-lock check, and will now also cover any significant oil leaks from the steering box and whether any ‘fitted as standard’ steering lock stops are missing. This is more likely to affect those of you testing larger Class 5 vehicles, as not too many light vehicles are fitted with external lock stops.
Power steering.
Checks to
power steering will now include a check of the fluid level. But because there is no need to remove the reservoir cap, the check will only apply where the fluid level is visible in the reservoir.
Any inappropriate repair or modification to a
power steering component will result in a failure – so a pair of tights in place of the drive belt will not be acceptable! The serious misalignment or fouling of power steering components is also an RfR.
The inspection of fluid pipes for damage and fouling will now also include excessive corrosion.
If a malfunction indicator lamp – fitted to warn the driver of a problem with electronic power steering – is illuminated, indicating a failure in the system, this will be an RfR.
Suspension, wheel bearings and drive shafts.
Testers should be careful to consider the guidance in the information column and the introduction section of the MOT inspection manual before rejecting any modified or repaired suspension components. But to make life easier, the team at VOSA has replaced all the RfRs for unacceptable repairs with a single RfR.
You are already checking all front drive shafts and those at the rear that form part of the suspension. As a result of the Directive, you will also have to check, where fitted, support bearings for excessive wear, and drive shaft inner coupling gaiters that are missing. The RfR for gaiters has also been changed to cover all aspects of the gaiter failing to keep the dirt out. Front to rear propshafts still remain outside the scope of the test.
Parking brake lever mechanism and associated mountings.
Electronic
parking brake (EPB) controls have been added to this section, and testers will have to make sure that all parking brake controls have not been ‘inappropriately repaired or modified’. The team at VOSA has defined this as ‘when the repair is obviously likely to adversely affect the roadworthiness of the vehicle or if any modification has seriously weakened the component’. If the vehicle is fitted with an EPB, testers must also check that the EPB warning lamp does not indicate a fault.
Service brake control.
As before, testers will be asked to check that the control has not been inappropriately repaired or modified.
Anti-lock braking systems
Also included under this section are checks to any electronic stability control (ESC) system fitted – called variously ESC, Electronic Stability Programme (ESP), Dynamic Stability Control (DSC), etc. To take account of the additional item, the section has been renamed ‘Anti-lock Braking and Electronic Stability Control Systems’.
The new checks will cover the condition of ABS/ESC components (which are generally common to both systems), electrical wiring, the ESC switch, and the presence and operation of the ESC malfunction indicator lamp.
Mechanical brake components.
Additional checks of the security of brake cables, rods and joints must be made and testers should fail any mechanical brake component if it has been inappropriately repaired or modified. The condition and operation of brake slack adjusters – usually only fitted to very large vehicles with air braking systems – should also be checked.
Braking systems and additional braking devices.
To avoid the repetition of certain checks that apply to a number of sub-sections, the team at VOSA has changed the title of sub-section 3.6A of the inspection manual from ‘Leaks’ to ‘All Braking Systems’. Leaks will still be part of this sub-section, but checks on the security, condition and operation of braking system components have been added. Checks for inappropriate repairs or modifications to braking system components will also be included.
As well as brake valves, sub-section 3.6E will contain additional checks on load-sensing valves. Originally only checking the linkage, testers will now need to check if the valve itself is also:
• seized or inoperative
• defective so that its function is impaired
• incorrectly adjusted.
Testers already check the brake fluid level – but the brake fluid warning lamp being illuminated or inoperative will be a new RfR.
Brake performance.
Another new RfR coming in at the end of 2011 is if, during a decelerometer test, the vehicle deviates from a straight line when the
parking brake is applied.
