Range Rover (LP) V8-4.0L (1999)
Suspension Warning Indicator: Description and Operation
Air Suspension Indicator
If the Air Suspension ECU (Z165) detects a fault in the system, the ECU will inform the driver by intermittently grounding the Warning Lamp Relay
(K155) for 30 seconds. This causes the Air Suspension Indicator to flash for 30 seconds. After 30 seconds the indicator will remain ON until the repair
is made.
