Corsa C Z22SE fitting Guide

corsaZ22se

i find parts at breakers or on here when someone breaks a car, or use genuine parts from LMF, Autovaux or Vauxhall dealer.
be sure the chains have been done before you fit the engine as its engine out to do them in the corsa 🙁

Don’t suppose you have any pics of the relay mods you have done?

Its just swapping the trigger wire from earth to live or the other way under the fuse board.
Cut the wire and either run a constant earth for a live switched or an ignition switched live for an earth switched.

On modifying a loom now to run Z22se but about 4-5 of my pins don’t match what your diagram says
Mine seems to only have one wire for immobiliser
No solid red in pin 17
Pin 18 witch is meant to be red was blue with a red tracer
And I can’t remeber the other ones that were different
Have you ever had this before?

corsaZ22se

What loom are you talking about? which engine/car?
Immobiliser always has 2 wires on all Corsa C's and all z22se that i have seen.

I’m repining the engine bay harness that plugs into ecu the same plug id repin for zlet ... I got told it was off a z12xe but a few of the PIN numbers on your pin out were different to this harness

corsaZ22se

Z12XE and Z12XEP are different, maybe that's what you have?
When i did mine the pins were different on the z12xe to the z22se, as in a different type of pin so they did not fit the z22se plug body.
all Corsa C petrols do have 2 wires which connect to the immobiliser though.

I may do a list for the Z12XEP over Christmas as a friend wants me to do his one.

graham_harris

Yeh worked out today that this loom is defo a z12xep loom so that will be my problem

Wondered if anyone knows what pin on the ecu the service indicator to the clocks is by any chance as i've not been able to find any pinouts showing this. Cheers Liam

Service indicator?
do you mean the INSP that displays on the trip mileage display after start up? If so that is done thought the canbus on the Corsa C.

Its the spanner light that flashes on the dash on an astra g to tell you that you need a service ect but i cant reset it via the correct way so i want to find out what pin from the ecu feeds the light if that makes sense cheers

corsaZ22se

that's the EML light you need to read the codes, fix the fault then you can clear it.
Vauxhall's have 2 EML lights, engine with spanner is usually down to an emissions fault and the engine with the electric flash is engine electrical faults. both will store codes
