CHECKING THE DROP SENSOR
With the engine off:
• Remove the front cover, see (REMOVING THE
FRONT COVER).
Check that the sensor (1) is correctly fitted (with the
arrow printed on the rubber element facing upwards).
• Partially remove the fuse block (2).
• Disconnect the two-way connector (3) (white/
gray) and carry out the relevant measurements
(on the sensor-side terminals).
On reassembly, make sure that the electrical
connector (3) is correctly coupled.
• Use a tester (scale x 100 k
Ω
) to measure the
resistance between the terminals of the black and
black/white cables (N - Bi/N).
Standard value: resistance 62 k
Ω Ω Ω Ω Ω ±
15%
• Remove the sensor (1) and rubber element from
its seat and incline it sideways by an angle
greater than 45
°
(simulating a situation where the
vehicle is lying on the ground).
Standard value: 0 - 1
Ω Ω Ω Ω Ω
If the resistance differs from the prescribed value,
the sensor (1) must be replaced.
• Repeat the operation, this time inclining the
sensor from the opposite side.
