Hullo there......Big fan of the mk 2 and had a few years ago and i'm asking for some help on a Calibre which is gettting restored at the mo.Can anyone tell me where the diagnostic plug for the ECU is and what pin's it is to plug in a fault finder.Engine was just fitted from a mk3 8 valve sri.The car will star but wont idle ant E.M.L comes on.I have a fault finder but dont know the codes either.Any help greatly appreciated!!...And top site aswell!!

Hi mate and welcome!!!

This should help you! ;) ;)

Engine ECU fault codes  2.0 8v, 16v, Ecotech, Turbo, V6

Information from Bob Rawle

Dis-engage the diagnostics plug from its socket.

This is positioned at the rear of the engine bay on the passengers side on cavalier/calibra’s, on the astra3 it’s in the fusebox, and on vectra’s around the handbrake and omega on the panel by the fusebox.

It has 10 pins.

Short pins A & B to read the engine ecu codes. Brown & Brown/yellow

16 pin connectors, On the Vectra / Omega short pins 4 & 6

Start the engine, management warning light will start to flash as follows.

The code 12 is first flashed three times, this is a marker.

If a code is stored it is then flashed three times.

The code 12 is then flashed three times, this is a separator.

If a 2nd code is stored it is then flashed three times or the first code is repeated.

The code 12 is then flashed three times, this is a separator.

etc

Once all codes have been displayed then stop engine and remove wire.

To clear codes you should disconnect the battery for a minimum of

10 minutes and then re-connect. This also has the effect of resetting

the ECU parameters to their defaults and forces the adaptive learning

circuits to start again. Within approx. 200 miles the ECU will have

adapted.

Motronic operates on a 20 ignition cycle basis after that the ecu will revert back to base settings also 80% of the codes listed do not apply to motronic 1.5 there are for motronic 2.5 ,2.7 & simtec also all codes now have moved on to 4 digit lines so you can break down a fault to find out where the fault is > useing a 4 digit code will tell you if a fault is on a feed ,earth or on a unit or sensor its self the best way to tackle your problem is to have the code read properly the break down the code then you can pin point the problem

Also as Karol said its best to stick to one system as by mixing & matching componets will also give you faults you can get a gost code by fitting a component that isnt matched to you system with there not actuly being a real fault there

Recipe

1x novice

1x piece of wire

1x dead ecu

dont mess about with things by shorting out pins one mistake you could end up putting 12v down an ecu or actuator earth then you will be worse off than you are now

True but if you buy a fault finder that is what the instructions tell you to do? and the adaptor for vauxhall is a bit of wire with the pins on the end to fit in the plug :(

it's like watching a father and son argument with you two at times  ;D

Think if I was his son, he would have disowned me by now!! :Ha :Ha :Ha :Ha :Ha :Ha

And if I was his husband/Wife he would have divorced me!! :Ha :Ha ;D ;D ;D ;D ;D ;D
