tc lights on and keeps stalling 2.5 v6
« on: 19 July 2007, 21:39:02 »
hi everyone

In need of some help replace the abs ecu for the usual reason but now the tc light will not go out and she stalls alot when on idle and a loads put on from the pas or aircon (bit like fast idel is not working)

She was ok before the change and was thinking she would need pulging into a tech2 to set the ecu (it was a new unit from vauxcav in wakefield.

Any help please

Tech2 may help explain why TC light on.  I've seen a few supposedly refurbished ECUs with these sort of issues...  ...though the stalling is a new one on me...

can not work out the stalling either was woundering if i did not reconnect the fast idle or somthing like that when i canged the ecu over but can find of think of any thing I have missed. The only idea i can come up with is the speed sensative side of the ecu has to be set up by a tech2 but was not very sure of that one. I forget to say its a 2000 plate if that makes any differance.

Just to let you know i found a great trick putting the torx bolts back in on the ecu (only took 5 mins for all 6) if you put superclue in the head and glue the torx head to it you can fit the screws no problem and the clues not strong enough to not break off when you take the torx head out.

That is the exact issue Steve W had when he replaced his, (then I Bought it)
Sounds like a blank (unprogrammed) ecu, mine stalled, but only for about the 1st minute from cold
TC light always on.
I replaced the bulb, got it on tech 2, set 3 litre, auto.
All instantly fine, light out and no more stalling.
