About Power Steering ECUs

The power steering ECU (Electronic Control Unit) is a small electronic metal box which is located above the steering column assembly behind the dashboard. It is responsible for determining the amount of power-assist to use and the direction of power-assist when operating a vehicle. It works by assessing signals from the steering torque sensor and the speed of the vehicle through ABS and applying the correct amount of pressure to allow the driver to exert less effort when driving. Should the vehicle not have ABS, the power steering ECU relies on speed signals from the speedometer. This system replaced the original hydraulic system, which was slow and heavy and could cause dragging of the pump on the engine.

During its operation, the ECU controls the motor by rotating the steering gear pinion. Should the ECU become faulty, it will signal its error by communicating with the electronic warning system and a warning light will appear in the vehicle. Upon driving you will most likely experience very heavy steering which will usually be intermittent at first, but if left alone will become a permanent situation so a swift repair is necessary. A full ECU replacement may be required in this circumstance.

Mercedes-Benz trivia

• The longest sedan vehicle available in today's car market is the S-Class Pullman, at a mind-boggling 6.5 metres long. Bear in mind that the average length of a sedan is only 4.7 metres!
• The Popemobile is a Mercedes Benz M-Class SUV. It's not a standard model, however, and has some added features like an inbuilt oxygen system and bulletproof glass.
• Mercedes are responsible for a lot of 'firsts' in their long history, including the world's first production of a diesel car. Very impressive, but it only had three wheels. Production stopped pretty quickly in the late 1950s.
• Ever noticed that you've never heard a Mercedes rattle or make any kind of squealing sound? You never will either, because all of their vehicles are welded in up to 10,000 places! You're not going to find a loose nut or bolt rolling around.
• Karl Benz might have patented the design of his Motorwagen in 1886, but it was his wife who jumped behind the wheel first for a quick (as quick a 0.9hp will deliver) 120-mile tour through the countryside of Germany. Poor Karl didn't even know!
