Renault Grand Scenic 1.6 - No power steering or steering lock #

Lets see if I get it right this time, without getting any stick.

I've a Renault grand Scenic 1.6 with no dash lights, no power steering or steering lock and now Ive lost the key. Nice huh.

I've taken the car to Renault to have a key programmed. The clip wont communicate with the power steering module, like its not there, and Renault's technician can't move forward to anything else as this problem is preventing them from doing so.

I've a Renault Scenic now which starts but has no dash display, power steering or steering lock.

First things first I have to get the power steering on line, and the steering lock if these two co inside so I can take the car back to have the clocks fixed as it is a common fault which was covered by watchdog and will be fixed for £100.

Ive taken the steering rack off for an examination. there is a main power in, black and red wire, which connects to the power steering ecu/module. A five wired plug, which comes from somewhere.
underneath this plug, there is two other plugs. These have wires running to components attached to the column, and the power motor. Finally there is 3 6mm wires, Red, black and beige running to the power motor, from the module/ecu.

What I have done so far is check the power in to the module which is good, with ignition on or off.
The three wires from the module to the motor do not give a live reading so I took the pump of, put a multi meter to the black and red wires on a continuity test and the meter is beeping, telling me that the pump is shorting out. I think the motor has gone and taken the module with it or the other way around.

Am I doing the right checks, and taking the right action???

I am getting another column for the car with ecu/module and components. Will the new module/ecu need programming to the car???

Morning Martin,

'I took the pump of, put a multi meter to the black and red wires on a continuity test and the meter is beeping, telling me that the pump is shorting out. I think the motor has gone'

Any standard motor must have continuity through it or it would not work. Dont condem it on this alone.

Ok.
I thought that live and neutral sholdn't cross paths.

No neutral on cars Martin, power and earth at any basic motor needs continuity to allow current flow through the motor.

I know that on a car earth and neutral are the same. On the battery you get + and -. and then you get earth locations.
I may be sounding like an idiot, but I dont mind.
If you connect the + and - on the battery you'll brake it. Isn't the + and - joint together going to cause problems.
The ohms reading from and 2 given wires is .03 ohms

Hi Martin,

'I may be sounding like an idiot, but I dont mind.'

No, idiots are people who dont know but still wont ask

'Isn't the + and - joint together going to cause problems.'

Only if there is no controling resistance between the two to control current flow.

You had originally stated there was continuity between the two, NOT resistance thats why I had replied to advise as above.

Regards
Sean

Yes there is resistance. If I run a direct power source to the pumps wires, red to red and black to black then there is a spark at the black connection and smoke, so I terminated the connection.

I'm the best ain't I.
Of course it's the column not the rack.
I did put the year in the fields on the start page, but it doesn't come up. Its a 2006 Renault grand scenic. engine code k4M 766

Time to ask the customer has anything been done before, like has the column been changed before,
has it ever worked in their ownership etc.

It may be the column has been changed already !!!
There are several type,s and from my experiance the clip looks via the chassis number entered for the type that should be fitted. I maybe completely wrong, but when using the DEC it auto-searchs and has always comm,d when the clip would not.
Once into the ecu, the column will need to be configured, for things like engine,amount of doors and wheel tyrs size etc.
