Had a this fault show a couple if times since yesterday asp when going over a bump. The GAP tool says it's the circuit open or short to ground front left height sensor height sensor but could it be also the top strut wires? Seems like it's just a momentary break or ground as it clears itself after ignition off. 2012 TDV8 Vogue (L322)

From the Adaptive Damping chapter in the DTC section of the WM:

electrical fault
Disconnect electrical connector to height sensor and inspect
connector pins & terminals for evidence of corrosion or water
ingress. If no corrosion found, disconnect harness at control
module. (A) Check for short circuits between any of the three
terminals and vehicle ground. (B) Check for electrical continuity
between the two connectors for each of the three terminals.
Reconnect electrical connector at control module only. C) Check
voltages at terminals within height sensor connector (sensor not
connected): voltage to sensor ground connection should be ~0V,
voltage to sensor signal connection should be ~0V, voltage to
sensor supply connection should be ~5V. All voltages should be
within ± 0.15V Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"
