Hi gang

Having problems with RRS, have yellow brake pad light on, traction light on, rollover light on and display saying reduced suspension ride height ( although it looks ok ) but I'm unable to select ride height.

Plugged into to diagnostic reader code are as follows:

P1935-00 Brake Switch / Sensor Signal Permanent (Have Replaced with new one, no effect all brake lights work ok)

U0416-86 Invalid data from vehicle dynamics control module Permanent


Got to be something simple, because other than that alls well.

Any help would be much appreciated

Just a minor query, did you use a new genuine LR brake switch? It has been reported that others can cause problems/failures, same as brake light bulbs I believe.  John

RRS MY12 SDV6 HSE. Sumatra Black/Ebony & Walnut + Dynamic Pack, + Cold Climate Pack + Memory Pack, Digital TV/DVD, Premium Leather, Cornering Lights, Cooler/Fridge Box, & most Options.

The brake pad light is triggered only by pad wear to the limit or a break in one of the two sensors wiring. Both easily checked.

First thing to check for suspension related warnings is the state of battery charge - low volts upsets some of the systems so check voltage across the battery terminals engine off but after car has been sitting overnight i.e. not just after it has been running. Anything less than 12.4 ish is too low. Try fully charging the battery.

If you need professional help - you are in luck as there is a very good independent called Landers near you in Houghton Regis:

I've seen it put the yellow ! pad light on for the hell of it when other lights have been on,

Andy - I must RTFM more often
Seems the amber (yellow) also indicates problems with EBA or EPB systems so yes it makes sense that it can be thrown up by some other unrelated fault. I think this is what people call 'cascade faults' on the Canbus? 2008 MY Java Black TDV8 HSE

Sorry guys been any from my desk, the brake light switch was from Euro Car Parts, not LR.

Also checked voltage with multimeter, battery voltage all good.
