Title: fault code help on traction control
Post by: nick v6 on 08 October 2009, 19:26:12
after the garage wrecked my mig doing the mot and i changed the abs unit to get the light to go out i still had the TC light staying on
i have put my diagnostic machine onto the car to see if it just needs clearing and it keeps coming back on
ive saved the fault code to my laptop and this is what i get

"My Naff Code Reader" 080805 - PC based diagnostic tool



"My Naff Code Reader" - KW82 Communication Window> 1994|Omega-B|Chassis|ABS-2SE (+TC)

KW82 protocol initialized.

ECU ID= XD,90447588,0273004049,BB27355, 4,



Total number of fault codes: 1

00071 - Transmission Ratio
Present

any ideas anyone

no probs mate
im going to try a live run so that the diagnostic can test rolling speeds

i think 1 of the sensors have been knocked :(

can't think why for MOT but anything on the gearbox? Was the engine running when you did the test?

ive done it with engine running and with just the ignition on both say the same

That code suggests transmission / ratio problem with is separate to the ABS / TC.

I would check all the leccy connectors are plugged in ok on the box

With your car being a manual my guess would be that the abs ecu is off an auto and hence is complaining about the lack of signal from the auto box (which the car doesn't have).
Hence the abs ecu needs a chat with a tech2 to set the variant code correctly.

when i got the abs unit me and the seller made sure all the part numbers and the code on the yellow sticker on the unit was the same

How does it work out the ratio? Does it compare road speed with engine rpm? If the ABS/TC was reporting a fault would the gearbox store a fault as a consequence?

Maybe the fault will clear once the box has had a chance to work through all the gears with a working ABS/TC ecu.

i would have thought from the diff, as that knows how fast/slow each axle is spinning.
Title: Re: fault code help on traction control
Post by: tunnie on 08 October 2009, 21:20:03
unless an ABS sensor is fubared and thus giving a false signal on how the axles are rotating.

I'd assume the TC works by comparing the speed of the none driven front wheels with the speed of the rear driven wheels. If they both accelerate at the same rate then the rear wheels are gripping ie not spinning. If the rear(s) are accelerating faster than the fronts, then the TC needs to do something.   :-/  :y

would check for a rogue wire, from spec a boom cannot upset the sensors lol  :y

Did you have a new ABS unit, or the old repaired?

it was a second hand unit with the same code on the yellow sticker and the same bosch number

mine used to be a 2.5 auto
its now a manual
vauxhall says the engine is a 3litre

reason I ask, regardless of the label / part numbers...

they also have a config...

which can be

not set
or
engine size
and
gearbox type

When mine was replaced, it was brand new, and had no config....this caused several issues, such as TC light on (and a stalling issue)

I am thinking yours came out an auto, so cannot see the auto data it is looking for, hence throwing up a fault.

do you have easy access to tech2 or "My Naff Code Reader" (maybe)?
Title: Re: fault code help on traction control
Post by: Jimbob on 09 October 2009, 21:13:34
ahhh just reread....you have "My Naff Code Reader".

now on later abs ecu's (ie 98 onwards) "My Naff Code Reader" can set the varient coding. ( no idea on earlier, but doesnt hurt to check for the option)

ive never tried it, so cant guarantee success...

off the top of my head, in the abs menu
you should have fault codes, live data, special functions (lets you activate pump) and programming, where you can specify engine and gearbox type.

may be worth a try  :y

cool, always like to know the end of a story...


did it say how it was programmed?

and set correctly, and light out and fault code gone?  :y

i used the setting ion the "My Naff Code Reader" to change the settings as it was saying that the ecu was automatic so i changed that to manual with a bit of googleing to help me and got it sorted

lights and the tc switch works :y

I agree. Likely to be that the unit is incorrectly coded for the vehicle.

Let's try that again after reading page 2. ::)

Yes, it's bound to be the variant coding. :y

Glad it's sorted.
