Diagnostics C5 2002 110 Hdi

[ando7p]

Hi all,

 

Just bought my first ever Citroen!! Have previously had the pug diesels before and being happy with the engine decided that it was time to have another. I liked the look and drive of the C5 so plumped for one.

 

Being used to the older sort (pre-plug into to find out what is wrong) I am unsure as to what exactly I need to be able to get into the various computer systems to be able to diagnose and repair as necessary.

 

The actual model is a 2002 (52) 2.0 HDI 110 SX. I have no idea as to the OBD connection compliance is nor where it is (reading other posts suggests its in the glove box - will look later today).

 

Would somebody please be kind enough, if they know, to tell me exactly what the connection is, lead description, hand held device recommended or PC software recommended?

 

I have no handbook (none currently on Ebay) and cannot find any kind of 'Haynes' style manual so have no idea of what the fault codes will mean.

 

Any help will be greatly appreciated.

The reader I use is an Autel and it plugs in at the back of the glove box. There's a little panel which pulls out and uncovers the socket. But I believe the C5 didn't become compliant until late 2004 so whether or not pre 2004's have the socket - I don't know.

 

The buzz is that Haynes are producing a manual for the C5 sometime in August. Revue Technique do a good manual for both Mk1 and Mk2 C5's but they are in French.

Ive got a y,51,52,52,54 reg and they all plug in no bother .

the 16 pin connector came out with the 2000 xantia before that it was the 30 pin connector so all the cars that I have seen newer than 2000 have the EOBD ( European on board diagnostics ) 16 pin connector as it was the law but only came into force in 2004 but used long before that date to tweak the system for the dealer only that's when it was hard to get diagnostic stuff the punter could use, from 2008 it will be compulsory to only have CAN ( control area network ) and much simpler to integrate as its fly by wire tech and very interesting though not new by any means

Many thanks for the responses. Now then, where do I get the fault code list? Thanks in advance.

;) Many thanks. I eagerly await delivery of my reader and getting it to work!

[techbod]

remember fault codes are only a guide to the problem ( interpreting them is a skill/art on its own ) ;) but we all have to start somewhere and there are los of internet sites to assist you there,

 

just Google obd

Bought an ELM327 USB (serial conversion). Connected to the lappy and ports configured. Software sees the ELM but not the car. Get a message that the software cannot locate the ECU.

 

Does anyone have experience with one of these units and possibly what I am doing wrong?

[techbod]

don't waste your time there the system is far more complicated than that because it uses multiplex and an old system, ELM 327 is also multi protocol but restricted to engine management because of free software and a licensed software is required to probe the full system

[ando7p]

I have fully licensed software that checks lots more than the free scantool, but returns cannot locate the ecu, even though once connected to the OBD socket the box TX flashes, inferring connection to the car.

 

Even if the free software is carp, I still cannot get the software to read anything from the car. The software tells me that the ELM is live, but will not connect to the car; thats my problem.

[techbod]

not an easy one because of your lack of knowledge on computers ( that's not an insult by any means ) I was on the PC in 1985 when the games machines were around and ill bet you were on the omega relevant to the play station today ;) very nice system indeed and had lots of fun there but times moved on and even I find it hard to keep up ;)

[ando7p]

PC knowledge isn't the problem. The lappy is correctly configured to accept the ELM as an interface and all the software registers this. Even checked the firewall to see if that treated the interface as a network device, and have surface glanced for resource conflicts but the outcome is still the same.

 

My problem is the lack of understanding as to the ELM chipset and OBD. Know nothing about them.

 

FYI - I was programming Z80 processors in 1981 in assembly code. Nowadays I write programs to create complex reports for a large company. I have built and configured more PCs than I care to remember. I am old school and maybe a bit too long in the tooth to be able to quickly understand how this device works, or if I am operating it properly.

 

Just wanted to know if the ELM is compatible with the C5. If it is then I must have a conflict that I haven't found yet .....

[techbod]

my appols im not sure if it would work on the C5 but it should if its as new as 2004 that when the EOBD became law and CAN bus was being used ELM327 is a topic on a few sites,

Thanks for the info. Will try setup on a petrol younger than 2001 to see if all works. Going on my annual hols so won't be able to see for a week or so. Will most likely turn out to be a conflict on the lappy.

 

Just trying the 'quick' way before going mad on checking all resources first ...... not always the quickest way though!!

hi, i too had the same problem, i took my c5 hpi to the garage where he plugged in his handheld snap on diagnostics tool, this would connect and then disconnect. i could not expect the garage to try allday so off i went with a bee in my bonnet. i then purchased my own handheld diagnostics tool for £90 from bullseye. before i connected it i disconnected my battery for 10mins and my ecu. i reconnected my ecu and left it for 1 min before reconnecting the battery. i plugged in my cheap scanner and it read it first time and works first time every time now. you may want to try the same as i dont think it will be u or the lappy or the diagnostics reader. just the c5 playing up as they always do. also check the wires at the back of the glovebox leading to the connecter as these may be loose.

I have no handbook (none currently on Ebay) and cannot find any kind of 'Haynes' style manual so have no idea of what the fault codes will mean.

 

Haynes do a general manual listing diagnostic codes. Halfords sell it.

 

Haynes Manual on Fault Codes

 

Also, see this link that has been posted before found by search function:

 

Peugeot and Citroen fault codes - BBA Reman

 

Also some advice from Citroen techs in this thread:

 

PSA fault codes? Useful?

 

Hope this helps...........................

[techbod]

all the codes are relevant but its only a guide to where or what the problem is, Citroen didn't give any information on P1 codes so ill assume they don't want anyone to know unless its 2004 when they had to by law ( they use P0 codes for the same thing as P1 codes so basically the same thing ) but P1 codes are manufactured detailed codes where as P0 are generic and now the cats out of the bag and most know what the P1 codes are its down to interpretation of the fault and not change things you think are the problem that's when it turns into a mine field and you waste money,

 

if not sure always ask ;)

[ando7p]

Thanks for all the tips / advice. Have been away to the sun and returned late last night so have not had time to try anything. Got a free night tomorrow so will try again in earnest. Fingers crossed that I can isolate the connection problem ....

 

With not having a manual I do not know if the radio / CD is coded so ....... is the standard equipment in a 52 2.0 HDi SX coded? Thanks in advance.
