Year of Manufacture *: 2004
( Optional ) Engine Code or CC: 3.7
Vehicle came in a few months ago with an intermittent speedo fault and abs/esp/bas lights coming on and transmission going into limp.
Customer said it happens now and again he pulls over puts vehicle in park and restarts and lights reset.
He did this the other day and it stuck in park which turned out to be the brake pressure switch so replaced and all was good.
Still has intermittent speedo fault etc.
When the fault occurs it is randomnly can be every day or not happen for months. The speedo drops to zero, ABS ESP and BAS lights come on together and vehicle goes into limp so wont chaneg gear (auto).
I am reckoning its some sort of speed sensor issue however I know very little about the system and as far as i can see it takes it speed reading from ABS sensors.
What I need to know is which sensor controls the speedo as this would be the one I'm having issues with, If there is a seperate sensor where is it or does it use one ABS sensor in particular?
Only fault code I have had out of it was C1000 Control unit fault ABS ESP BAC.....means not a lot!!
Help much appreciated as the customer wants to set fire to it!
