I washed the car the other day & decided to give under the bonnet a quick clean. I wiped the engine & inner wings with a wet sponge & then started the engine. The center L.E.D. display said

leave it to dry for a while then see if the lights are still there.. ... - .- -.

Hi Stan, thanks for the reply. It's been over a week now & no change. Drove the car 60 miles today with all the lights stil lit & it drives fine. Maybe it's just a sensor? Oh and the steering went VERY light when it first happend but this seems to have sorted itself out

If it was any other car I wouldn't drive it with the dash lit up but the car seems to have something wrong permanently & I just don't have time to leave it with the dealer every few weeks. Range Rover 4.4 V8 Vogue

dont know why you're having the lights unless you dis-connected the battery and didnt reset the steering parameters....

your suggestion of getting a reset tool is a good one..something like the IIDTool lets you play with the CCF as well.. ... - .- -.

Try disconnecting the battery waiting 15 minutes then reconnect...

Carryout the steering angle sensor reset by turning full lock to the left then full ock to the right then back to centre....

That may kick it back into action...

I had similar and it turned out to be a dodgy ABS sensor....

The ABS system in connected to the same data bus as the EAS....so a fault in the ABS system usualy freezes the EAS too (annoyingly).

The reason it knocks out the HDC & DSC too, is those two systems also use the ABS sensor information to maintain control down hills and to monitor the traction of all 4 wheels for the DSC.

Getting a diag tool is a fab plan 

Thanks for all the help guys, I'm off to disconnect the battery to see if that helps and have just Googled the

Integrated interface diagnostic tool (IID Tool) for RANGE ROVER L322 - FOR 2002-2005 £231.25 exc. VAT

Seems a bit pricey for a small box? Does anyone do a cheaper version which does the same?

Is "as far away from any Land Rover product as I can get" anywhere near Kent?

If so, you are most welcome to pop over & get your codes cleared for free on my Hawkeye.

Let me know if I can help  Quis custodiet ipsos custodes?

It is probably water got into the ABS module and causing poor connection. This will cause all the other faults as all are on the same loop and a ABS fault stops the power getting to the other sensors, causing an alert.

It is easy to open the module and dry out with hair dryer then check for corrosion - 10 min job. It is situated to the rear of the engine near the bulkhead/windscreen.

Never power wash the engine!! There are too many electrical gubbins.

It could also be a sign of a tired battery- I presume you were cleaning car, lots of opening/closing doors, etc, and these kinds of error messages then pop up. My experience is that the car is sensitive to low batt voltages. The 15 min disconnect, followed by resetting the steering angle lock to lock should help.

+1 what jim said..


blackbox faultmate costs around £1000, the IIDTool costs around £250 and then consider how much a dealer charges to reset your error codes . ... - .- -.

The Hawkeye is under £300 and is not VIN-tied so you could use it on any L322.

I have both a FFRR & a D3 so it suits me really well but I cannot currently write to the CCF. Personal preference as ever

I suggest to have a good look at all your earth/ground connections as well as the clamps on the battery. Take them off, clean off any corrosion. On the battery clamps, put a thin coat of Vaseline to prevent future corrosion on the other connections use a proper electrical contact cleaner and if you don't have any, WD-40 also does a decent job just not as good as a good electrical contact cleaner. MY 2010 5.0 SC Galway green and sand interior!!
Have the Faultmate MSV2 Extreme to be tinkering with the settings etc. !!

This morning I disconnected the battery. Took off the box which was under the windscreen & behind the battery & cleaned all the connections & applied some contact switch cleaner and then some silicone spray after drying it out. The plastic box was slightly open so that may have caused the leak into the connections.

Started the car & all the warning lights have gone out apart from the orange one in the middle of the clocks, think it's skid control. It still has HDC inactive & Suspension inactive but both seem to be working. Suppose it's time to break the piggy bank open again & buy a reset tool.

Thanks everyone for all the help with my car, the knowledge on here is great  Range Rover 4.4 V8 Vogue
