Vectra C not starting after ECU and CIM change, please help!

[HoldenVectraC]

Hi I'm Daniel, I'm new around here but have searched a bit and still can't find the answers to my issue.

So I recently bought a Vectra C with a z22se engine and manual transmission, first started having an issue with the check engine light and error code P0601 which caused the engine to cut out, decided to replace the ECU and also the CIM and key / chip, which the parts came from a 2003 auto vectra c.

Now im having an issue with the central locking doesn't work from either new or old key, I also swapped the ignition barrels between CIM so I could use my old key.

Also now the engine does not start at all, coming up with padlock regardless of which chip I use with my key.

Check engine light shows and gives code U2106 meaning loss of communication with transmission control system probably because the parts are from an auto, but shouldn't the car still run regardless of this?

Any help is appreciated, thanks in advance.

Was the original divorced from the car first? Was the new 1 divorsed from the donor car?

Have you paired the new cim and new ecu to the car?

If you havnt done all of this your immobiliser will be stopping you. You need the pass code for your car.

I didn't think it was necessary when replacing the ecu, cim and transponder on a z22se, but guess I could be wrong, how do I go about programming it if they haven't been divorced? I'm guessing it needs opcom or tech2?

They would have been paired to the original car and would need to be "divorced" and then married to your car. I believe also that if the parts came from an auto then the system would be looking for something to say it was in park. My 56 plate won't let me start my car unless I have my foot on the brake pedal first. That possibly won't help either.

The Vectra C is totally different to all the other z22se fitted cars. It can be a right pain in the arse

 

[Dave Gilbert]

The ecu and cim that you have used need to be put back on the car they came from then go in with op-com and passcode and reset them.

same with yours on your car then put new 1s on and programme them into the immobiliser etc. Its quite straight forward onve you have done it but u need to do it stepby step

 

[HoldenVectraC]

Alright, so i used op-com to program everything and now none of the modules are showing error codes but the car still wont start.

When i turn the key to turn it on can hear the fuel pump prime and then when i turn it to crank can hear a solenoid sound from the passenger airbag side but the car does not crank.
Anyone have any ideas?

I have charged the battery and tried jump starting and also checked the fuses they seem fine, getting really frustrated now

 

[HoldenVectraC]

Alright i'm getting the following codes now:

U22105-71 CAN-Bus ECM Message Range/Performance
P0500-71 Vehicle Speed Signal Range/Performance
U2139-71 Invalid Signal from CIM (Steering Column Module)
U2139-7F Invalid Data from CIM (Steering Column Module)
B0173-05 Outside Temperature Circuit Open or High Voltage

Not sure how to clear these, also should they prevent the car from starting?

 

[Dave Gilbert]

Doesn't sound like the cim/ecu and immobiliser Is programmed to each other to me

 

[HoldenVectraC]

Yeah i'm not sure but i reset everything and programmed it atleast a couple of times and the immobilizer is showing the security code is accepted and programmed on everything, also i checked the vin code was correctly programmed into each module.
Anything i could have missed?

Also why would a relay tick in the dash?
Almost making me think it could be something else electrical stopping the car from starting like a relay or the starter.

 

[HoldenVectraC]

Been reading a bit online and now i'm thinking it could be the ABS plug as i remember it also threw up a traction control light briefly at some point.
Is there any way to tell if the ABS plug is the old one or the newer replaced one?

 

[HoldenVectraC]

Ok so i've checked and cleaned the plug and still no difference.

When turning the key to the position before cranking i get a click noise from by the glovebox im guessing its a relay in the dash.
Also the engine seems to make some little noises, not sure what that means, still getting nothing from the starter (not clicking or cranking at all).
I havn't checked the starter for voltage or anything but is there any way to tell if it is alright? Also it seems that someone has wired in a relay by the starter, not sure if this would cause any issue.

I might try reprogramming all the modules for the 3rd time, but not really sure what difference it would make because the last 2 times have just been getting the same codes from the instrument cluster, airbag and EHPS. The ECU and CIM are clear of codes so i'm unsure what is going on.

I ended up putting back my original CIM instead of the one that came with the ECU so i could always try the other CIM if needed, but i really cant be bothered taking the steering wheel and airbag off for the third time.

Any help would be great because I need to have this car sorted as I should be starting a new job within a week, last resort is to get it towed to the dealer but i don't really have unlimited money to throw at it so either that or get rid of it / scrap it if i can't get it running soon.

When I replaced my ecu I had a friend programme everything remotely on my laptop through op-com and team viewer so I don't know exact details.

Are u hearing the fuel pump purge? When you turn the ignition on?

Yeah the fuel pump does sound when turning the ignition on.

 

[Dave Gilbert]

I'm not sure what the immobiliser cuts I think it's spark. But could be fuel.

The ecu is a vectra c z22se ecu like for like? Same part number etc? Cos there's 2 vectra c 2.2s maybe u have a z22YH n fitted z22se or other way round. U wouldn't get a spark cos of the trigger wheel being different. If they even fit (I don't know)

 

[HoldenVectraC]

Yeah its both z22se, so no problem.

On a brighter note i managed to get it started but there is no ignition power to a relay which is hanging off the starter.
I got the car running by bridging the starter terminals and was running fine with nothing bad showing up on the dash.
Now just going to find why there is no power from the ignition switch to starter, going to investigate relays and fuses, see if there is any signal coming from the ignition switch.
If i have to as a last resort ill just wire a switch from the battery to the relay as a temporary fix so i can start the car easily and drive it for now.

Thanks for the help anyway ill post back the results.
