The core of the electro-mechanical power steering is a steering rack with two teeth engaged in the steering gear.)
still reading so I will post notes for my reference.
The components that assist steering are located on, and operate directly at, the steering gear.
The saving in energy over 100 kilometres is up to 0.2 litres.
(based on this, after calculations, savings of
7.9 gallons per every 930 miles(what I drive per tank), equals to, at 2.79/gallon, saving
$22.00 and
435 extra miles/tank. tank avg 930 miles could be
1365 miles. if conversion cost
$1,000.00, around
1 1/2 year break even.)
seems to be a lot of hidden components:
System overview
G28 Engine speed sender(... is of the Hall sender type. It is attached inside the crankshaft sealing flange housing.)
J104 ABS control unit(The signal for the road speed is supplied by the ABS control unit.)
G44 - G47Speed sensor (road speed signal)
J248 Diesel direct injection system control unit
J533 Diagnosis interface for data bus
J527 Steering column electronics control unit
J285 Control unit with display unit in dash panel insert Terminal 15
CAN drive
K161 Warning lamp
G85 Steering angle sender (... found behind the return spring with airbag slip ring. It is located on the steering column between steering column switch and steering wheel.)
J500 Power steering control unit
G269 Steering moment sender
V187 Electro-mechanical power steering motor(Effects of
failure: An advantage of the asynchronous motor is that the
motor can be moved by the steering gear even in a state of no voltage. This means that, in the event of failure of the motor and thereby loss of power steering assistance, the
steering can still be operated by applying a slightly greater amount of force. Even in the event of a short circuit, the motor will not become blocked. Faults are indicated by warning lamp K161 lighting up red.
this is interesting"
The electric motor with control unit and steering assistance sensors can be found on the second pinion. This design means that
there is a mechanical
connection between the steering wheel and steering rack. In this way, the vehicle can still be
steered mechanically in the event of failure of the servo motor.
In the event of failure of the steering moment sender,........ a fault is detected, the power steering assistance is shut down. This shut down is a soft and gradual process, rather than sudden. To achieve a soft and gradual shutdown, a
substitute steering force signal is calculated in the control unit from the steering and rotor angle of the electric motor.Faults are indicated by warning lamp K161.
wonder how the steering is with power off?
