United Kingdom 2005 Range Rover Sport Supercharged Java Black
Active roll control module fault

Hi. I have had my 2005 rrs 4.2 supercharged in at the local range rover specialist due to red suspension light on dashboard and after a diagnostic they have said the active control module fault is sending no signal which is causing the car to occasionally go into lowered suspension mode and all warning lights come on the dash. My question is has anybody else had this problem and sorted it thereselves. The red light is always on but the lowered suspension/hdc fault and all warning lights only come on if I start the car and drive straight off. If I leave the car running for 1 minute the car is fine and doesn't come up with any warning lights (except the permanent red suspension light). Hope someone can give me some advice. Cheers

1st check that you don't have a lamp blown in the rear light clusters.......... a failed brake light causes all sorts of totally unrelated warning lights to come up on the dash 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
2018 Melting Silver Mini Countryman PHEV - soon to be replaced

2nd, check that the module plugs are fully inserted. A loose wire will throw all manner of issues. If someone has tried disconnecting the plug for any reason, they may have pulled on the wires. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
