Title: speedo failed
Post by: coolsurfer on 16 February 2010, 11:17:00
have a 99 mv6 3.0l and have lost my speedo, and pas has got really light, there are no warning lights that have come on. when i used a scanner no fault code found, any one got any ideas or could it be the dreaded abs/tc ecu (aaahhhh). i had this repaired about 6 months ago when my abs and tc failed also had an intermitent speedo fault as well, but has run fine since.

Afraid, that's the classic symptoms of the beginnings of ABS ECU failure, the level of PAS is determined via the speed feed from the ABS ECU as is the speedo.

You could try cleaning up the sensor on the NSR wheel as this is where the feed comes from, but 99% it will be the ECU.

Sorry bud.

Do the ABS/TC lights come on?

If not, do they come on as they should when the ignition is first turned on, and then extinguish?

would say the speedo is gone you can check on mid display, if it works on mid would check the connection on the back of the dash display if that ok would think the speedo has gone if you wont a cheap one sent to you send a pm. few quid and p&P

Careful. 4 cyl and V6 speedos are different.

To get an exact match you will need the code off the circuit board & it will look something like:

88 481 707

If its an MV6 then I suspect that the code will end in 706 - just a hunch.

Code numbers still need to match though Rusty.

Pre-facelift clocks wont work in mini-facelifts

As you look at the rear is the number at the bottom left - just in from the corner and between 2 circular mouldings about a cm in diameter?
