Need some guidance on resolving “Transmission Fault, traction reduced” error.
This appears every trip and resets once the ignition is turned off.
The Haldex has been regularly serviced, the Haldex pump has been replaced with a recon unit, I have replaced the Haldex ECU.
The battery is relatively new and is in excelllent condition, the alternator has been replaced.
The tyres are all new and running equal correct pressures

The above seems to cover all the recommendations I have found to fix the issue

The fault codes are :
ATCM U0437-94 invalid data received from RDCM
RDCM P 1889-14 oil pressure pump performance

My independent Landy guy shares my bewilderment maybe the recon Haldex pump was a duff.

The symptom first materialised after I had run over something (metal, wood rock w.h.y)on M62 that clattered the underside and took out a rear tyre.
We have thoroughly examined the underside for damage to wiring etc, all seems fine.
Any further thoughts would be welcomed

Where was the replacement ecu from?
Is it new, is it for a Freelander 2, is it for the correct generation of haldex?

I had the same code about pump pressure low. A new haldex pump cured it. Landrover - turning owners into mechanics since 1948

The fact that the fault only occurs on start-up, and does not re-occur during subsequent running, leads me to think that something is either with a sensor, or of course the pump may be so ineffecient that it takes too long to get up to pressure. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

Thanks IanMetro It’s not on start up, it can happen any time during a trip, half a mile or 20 miles.

Bobupandown, It’s a used ECU but it’s the right one, G4. seemed like worth a punt given the cost of new ones, I’m going to send the original one off for rebuild and see if that solves it!

I've used this company before who repaired the haldex ecu on a VW Tiguan.

Found him very helpful, his website has plenty of info about haldex issues too. I'd imagine he'd be able to test your pump to establish if its working correctly.

No connection to him but seems like a decent guy. Landrover - turning owners into mechanics since 1948
