So I’m done wiring my car for CA just laid down a new harness Alright all wired up now started to test fit a lot of the electronics and plugs to make sure the car is good, and my master switch on the driver side lights up but is not working, the car cranks but no start and I can unlock the car but not lock it, I didn’t cut anything on my harness other than 3 mini vampires. Any suggestions? Have power lights etc. thinking it may be the JBE I get clicks for unlocking working properly but not locking, just cranks no start tire pressure light is flashing on and off and a random what looks like the roof of a car with a exclamation point. No radio or hvac but the radio has backlighting.

Car does not communicate in ncs or inpa I get a error when trying to chassis In NCSExpert to bring up vo. This is the error vin is faulty

[Hiroyue]

While playing around down at the JBE I could hear a audible click like a relay when moving the box a little other hand clicked lock and it did once that was all she wrote for tonight on it. Couldn’t get it to lock again no more clicking when moving the JBE box around.

List of non working no memory seats or power to seats. window switch drivers master side, all the others work though. I can make all of them go up or down by holdin the fob. no side mirrors, no locking of the car the car will unlock by using the fob or the center button but only unlock and I can will unlock the car and it wakes the car up and lights no radio or hvac displays no air but backlighting for radio no trunk light, car will crank but no start sunroof makes clicking no movement.
Oh no communication with inpa or ncs inpa doesn’t show battery or key ncs says bad vin

Excuse my bad wording I’m dead tired trying to sort this out I’m pretty sure when I dropped the fuse box part way through my gut job I needed to roll the windows back up to wire the doors and the master switch didn’t work then I had only taken the JBE out at that point nothing had been wired in yet was just gutting it.

So my breaker should have a JBE 2 I believe I should be able to get it Tuesday because of holiday weekend FML... does the JBE part numbers have to match or as long as it’s a jbe2 or 3 it will work?

you probably breaked or disturbed primary can bus in car and so you cannot diag anything
and modules do not communicate in car
you should provide detail list of the changes made

[Hiroyue]

Meaning the K can high and low?
The only changes that were made as adding PDC retrofit and comfort access it involves adding a 2 pairs of k can high and low which I joined at the wiring loom at the JBE harness, along with adding the power wire for the CA module. 2 wires pinned into the door for each front and door harnesses. Also adding a wire into the electronic steering lock line on the CAS.

disconnect plugs from ca and pdc modules and try again

[Hiroyue]

Had tried that both modules are not plugged in but wired in still. I’m debating on taking out the k can lines I added by the JBE,

Update tried again with modules unplugged no start same problems, removed mini vampires off CA to CAS and CA + PDC k-can lines by the JBE tried again no start same symptoms, I’m still really leaning to the JBE as my problem. I think there’s a short somewhere in it. Question regarding a replacement does it have to match my pn or realoem which is newer or just be a PL2RR?

[Hiroyue]

A de sync of the CAS to DME wouldn’t cause the no start or non communication correct?

you should try to read codes after you disconnected new retrofits

[Hiroyue]

So no communication still with retrofits dewired no start same symptoms, started to try and track down anything loose at the junction box dropped the fuse box and plugged the JBE back in while it was lowered and the car locked once and unlocked on its own right away. I checked the wiring on the rear plug harness that’s facing the front of the car and it seems to be nice and tight nothing loose and pins are in place.

The thing that’s leading me to where I am is that when I’m moving or pressing on the JBE it would click I can hear the relays chattering feel them as well. I’ve been thinking about this and I dropped the glovebox like a year ago trying to track down why my horns went out I remember touching the JBE and it started chattering but it stopped tried to start the car and it didn’t reinspected the fuse box pushed on fuse’s to make sure all in place and JBE and car started never looked back at it since then until this.
I’ve thought maybe the box isn’t all the way flush and plugged in but it won’t go back any further into the slot and it’s screwed in with 2 mounting screws above it.
So is there a way to reboot or reflash the JBE as it is? I though that I’ve read somewhere you can using winkey but I can’t get mine to work right I guess.

[ptpending]

when you do wiring jobs with can bus in some way, you can burn can bus transciever and then you may have symptoms as you have now
and you really probably have to replace JBE

[Hiroyue]

So trying to centralize if it was in the wiring that I had manipulated removed the JBE and played with the fob lock to see if it would latch. I got the car to lock a couple times but it would unlock automatically, if I unplug the JBE pull it out and re install while holding the bottom of the JBE box like in the middle it’s locked a couple ones but unlocks, I’ve checked with my scanners no communication still, I guess I’ve just been playing to see if I could find a sweet spot.
I’ve got a realoem pn replacement for my vin coming think it will be a week or two though...

[Hiroyue]

So I’m still waiting on the JBE coming, have same issues as I have been borrowed a friends k+dcan cable and got the car to communicate with inpa and ncs, car threw some codes k can communication, k can low etc but all were not present just saved cleared and tried to start to no avail. In ncs I recoded the JBE to stock still nothing. I can’t get my winkfp to work or I would do what Mac90 did to see if that would work, the only codes that have stuck around is dme relay starter motor timeout and pressure switch for the ac.

[Hiroyue]

So new JBE came in installed it no changes in problems. The battery was literally just replaced within a month and it’s on a ctek 4.3 while I’ve been trying to diagnose so battery shouldn’t be the issue. Unplugged the RDC or tire monitoring module and same issues, I’ve read that it can cause my issues if the module goes bad.
If the ELV was locked due to counter it wouldn’t cause my other issues correct? My assumption is the kcan is crashing due to a short or module what would be my easiest way to pinpoint this since It seems like I can communicate with the car.
Any suggestions on a decent inexpensive oscillating scope, I’m assuming I’m going to need one soon to tackle this.

[ptpending]

the standart procedure is to disconnect ECUs one by one and check if other modules available via diagnostic bus (for example INPA identify job)

[Hiroyue]

So list of codes pulled up by inpa clear them try to restart the car same codes come up. In identify on inpa all modules say status ok the only one that looks odd to me is the MRS doesn’t say a hw or sw number just 0’s

So in inpa under UIF it looks like I’m missing a lot of modules. Only the kombi and dde/dme shows my vin.

[ptpending]

VIN is not a problem
did this scan done with key in slot (ignition enabled) ?

[Hiroyue]

Yes inpa registers battery and ignition, and codes pulled with ignition tried as of right now this is what it threw.

[ptpending]

your DSC(brakes and stability) module is not available, also EGS(automatic gearbox) and RAD(radio)

[Hiroyue]

So if I’m thinking correctly aren’t those on different com lines? EGS is on pt-can RAD is most line?

DSC and EGS on pt-can, RADIO on dcan
