Z16SE: cod eroare P1530

M-am uiat mai atent la firele din mufa mama de la compresor catre magistrala de fire care trece pe langa ventilatorare catre ECM. Erau fin intrerupte izolatiile in mai multe locuri, iar un unele locuri coincideau la ambele fire de unde si scurt circuitul.
Concluzia:
Eroare -P1530-(4) Ismeretlen DTC - Detected sau -P1530 AC cut-off relay - circuit malfunction Wiring, AC cut-off relay, ECM --- s-a datorat celor doua fire intrerupte pe o portiune de 10cm, din loc in loc, de la mufa mama de la compresor catre magistrala de fire care trece pe langa ventilatorare catre ECM.

Umeaza sa inlocuiesc acea portiune de fire. Caut niste cabluri electrice cu izolatie rezistenta la temperatura, asemanatoare cu cele originale.

Ai eroare si compresorul pleaca?
Ai AC automat? Daca da, eroarea ar fi pe modulul de comanda AC

Sa reinviam topicul.
Am si eu eroarea P1530 (4) "Releu pentru cuplaj clima - tensiune prea mica" la Vectra B cu motor Z16XE cu clima automata. Acum cateva zile am schimbat compresorul, iar eroarea a ramas stocata si nu pot sa o sterg cu Op-com -ul.
@GL10PEL, nu ai mai revenit cu rezultatele, te rog sa ne spui si noua daca ai rezolvat problema dupa ce ai schimbat firele.

Am si eu o problema.....=>

2. Am freon, dar nu cupleaza compresorul.
a) De cele mai multe ori, siguranta termica a bobinei compresorului este arsa. Compresorul porneste daca e arsa siguranta?Daca pun compresorul pe direct ar trebui sa pornesca dak e arsa siguranta bobinei?
b) Senzor de presiune AC defect, se vede imediat pe tester; VERIFICAT ESTE OK
c) siguranta arsa, rar; VERIFICAT ESTE OK
d) modul comanda defect, rar; VERIFICAT ESTE OK
e) problema "pe fire", rar. ???

Hello dear friends from Romania. Greetings from Slovakia. This is probably biggest discussion I was able to found about the P1530 error. I don't speak Romanian but I hope for any help.

Can anybody, please, tell me, what was reason of that error? What was wrong? I tried to translate it, but I failed (we all know how accurate the google translator is...).

I have this problem on my Vectra C 1.6 16.V 74kW 2005 (non-facelift) with manual A/C. My problem is, that there is no voltage on the A/C clutch relay, the error is:

P1530 - A/C Relay Voltage Low
(06) - Present

It works only sometimes (like 10-15% when I turn on the AC it really works. But mostly 85-90% it does not work, even when LED in cockpit shows, that A/C should be working - but it is NOT). When it works, it works fine. Or when I short (connect) power pins of the relay, then clutch turns the compressor ON and A/C works fine. So probably there is no problem with compressor / clutch and these thing. I have enough gas inside it and pressure is OK as well. So it seems like there is only problem with getting that +12V on the A/C relay.

Is there anybody who had this problem? How did you solve it? Summer and hot days are comming and I don't want another summer without A/C . THANK YOU A LOT!

Thank you for reply. Yes, the P1530 is the only error according to problem with the A/C. Here are some values from opcom:

A/C Pressure (Air Conditioning) 960 kPa (it raised up to 1200kPa)
A/C Pressure (Air Conditioning) 1.0 V
A/C Relay (Air Conditioning) Inactive (even when I shorted / connected power pins of relay, this was still INACTIVE)
A/C Cutoff Mode (Air Conditioning) System OK
A/C Information Switch Inactive (when I pressed the A/C button this changed to "Active").


I believe there are some informations in this thread, but I can't translate it correctly, even with google translator. It translates some words absolutely incorrectly so I can't understand point of the text.

Hi zrb17.
For P1530 fault code, check wires continuity:
VECTRA C
- (Z 16 XE)
ECM: 51 (XC4) / UEC: 30 (XE3)
- (Z 16 XEP)
ECM: 48 (XC93) / UEC: 30 (XE3)

zrb17, have you checked the wiring going to the AC compressor clutch? In my case, those wires were partially damaged and made a non-permanent contact, hence AC was working 50% yes 50% no, even if the AC LED in the dashboard button was on. Check starting from the AC compressor towards the main wiring harness.

zrb17, ai verificat conexiunile merg la cuplajului compresorului AC? În cazul meu, aceste fire au fost parțial deteriorate și a fãcut un contact imperfect, prin urmare, AC lucra 50% nu, 50% da, chiar dacã LED-ul AC în buton tabloul de bord era pornit. Verifica pornind de la compresorul AC spre traseul principal de cabluri.

@zbr17 you have one single radiator fan or two?

One condition to AC compresor start it`s the dedicated fan to start.
