Unfortunately I don’t know of any T4 service providers near me - hence the use of Toaf.
Can anyone provide the readings across the pins on a working side impact sensor? On mine there is no passive resistance but both show a capacitance of 32nf. This is measured across the outside pins as the centre pin is not connected to the car. Online, sensors are described as, in general, having an inertial switch with a resistor in parallel or a pressure switch when they are mounted inside the door panel but there is no definitive description of how MG Rover units work (as far as I can see). Has anyone ever pulled one apart? |

"Each sensor consists of an accelerometer, microprocessor and serial link circuit. The sensor uses the accelerometer to determine the severity of a side impact, and if the impact is great enough to warrant supplementary restraint operation, the sensor communicates the need for deployment to the central DCU via a single line serial link. Judging by that description, I'd say that attempting readings across the connector pins is pretty pointless unfortunately. Simon

Excuse my ignorance, I’m very new to this but what exactly is RAVE? I’ve seen references to it but have no idea what it is (apart from things that used to take place in barns and were frequently raided by her majesty’s constabulary!)

It's the official MG Rover factory technical information; systems description and operation, workshop procedures, wiring diagrams, etc.

…. and the next question, is it available? Sounds like it could be useful as all I have is the Haynes manual and it only has limited wiring info.
Following Kevin’s reply, I have removed the carpet and a lot of the soundproofing is pretty soggy. I’ll get everything bone dry and check all the earth points though the old back is complaining a bit.. the carpet is surprisingly heavy! If nothing else, it’s kept me entertained for the last few months but hoping I get to drive it at some point! |

Will do Simon, fortunately I’m not in any rush as the owner is waiting for a cataract operation. Sensors are in the boiler cupboard and carpet is draped across the bonnet of my Series 3. I’m hopeful, given Toaf didn’t throw any communication errors, the sensors will be ok and, at worst, I might have to get an ecu as these seem more readily available. Anyone have experience of swapping these with Toaf or is it plug ‘n’ play?
