Hi all. This is my first posting on the forum. I have always liked the idea of being able to check my car's onboard computers, engine management system etc, and in looking around for such tools, I have found the ELM327 Motoscan code reader to be a tempting diy tool for looking at my SV6. Has anyone any experience with this type of unit? This package comes with the connecting cable between the OBD socket and the Motoscan box, and the serial cable between the Motoscan box and a computer. Preferably a laptop. Some software is available, but does it translate fault/trouble codes into on screen english? (I had a VT Berlina and used the Gregory/Haynes workshop manuals when servicing it. Between them, they gave some of the trouble/fault codes and what to look for).
I think this unit is able to look at codes from VX to VZ.
Any experience with this unit or similar devices?
Unless it supports CAN data its no good for VZ
LS1 doesnt use CAN it uses Class2 VPW comms
LS2 uses CAN
some of the generic scantools dont fully support the manufacturer specifics in the data stream.
"I have a scantool that supports CAN and have used it on all GENIII models, but it doesnt work on the VZ V6"
there is some data available on the UART comms bus that if you had the definition of the data stream you should be able to read.
what brand of scantool is it?
All CAN comms is supposed to be industry standard compliant so it should read it.
the tool may have to be specifically configured to read it.
It is an Auterra Scan tool.
yeah it looks like a good thing, not sure on the specifics but you may need to try configuring it for the saab version of the engine?
I have an Elmscan5 usb and it appears to work ok on my feb06 vz. It picked up 2 trouble codes but couldn't verify that it was what the dealers reset. If that's any help.
I have a multiple forum member reply here. It it the best way to go?
6385 Does the Elmscan 5 unit give any descriptions on a computer screen or just the code numbers?
VTSS350. The Autera Scantool does it use a computer screen or just code numbers?
Dr Bob. I had a look at the US site for the Motoscan ELM327 unit. It suggest a compatibility with CAN ISO 15765-4. Do you know if the VZ matches this standard/revision? Also is there a list of trouble/fault codes for the VZ published yet?
I have been chasing Haynes/Gregory publishers for a VZ Workshop Manual release date. The recent reply was 6 to 12 months away. Our local Holden dealer says the factory CD for the VZ is out now. About $300 buys it.
Hi diysv6, yes it gave a description of the trouble codes for me but as I stated I can't verify that is correct as the dealers wouldn't tell me anything.
I tried to upload capture of the codes that were a problem. My email is in my profile if you want more info, but bear in mind that I have only just had it a week.
i will look up & see if i can find exactly what revision applies to the VZ
also i will look up those codes tonight & see if they are correct.
Dr Bob, thanks very much for that. I'm very interested to see if their is some sort of relationship in what the Elmscan5 tells me and actual problems.
The backround to my situation is that I bought a brand new car and I had a front strut replaced at 4000km then I had "Reduced Power, Check Powertrain" at 6000km. Was reset at the dealers and a week later just a "Check Powertrain" This is after being told that my car is running like a dream and no faults are in it. Currently I'm looking at the "Long term fuel trim" (both banks) as there is a discrepancy on the readout. I bought the Elmscan5 to keep a check on what is happening with my car.
the Holden DTC description for these (06 MY only) is P2178 fuel trim rich during cruising/acceleration bank1 & P2180 fuel trim rich during cruising/acceleration bank2
these codes are not used in MY05
still looking for the comatibility version
oi wats this code mean????
U0155 - CAN-BUS no communication with gateway???
answer m,y question dont be faggots!
No need to be lippy here mate, if ya gve people chance to reply you will get your question answered,
U0155- is a break in communication between the instrument cluster and the pcm!
i wouldnt honestly be worried about it as ive usually seen it occur on engine startup, think of it as a ping timeout between the pcm and the cluster for a brief moment!
