equire no adjustment and are non-serviceable items.
Accelerometers


The three accelerometers:
Sense veh
icle body movement.
Gen

erate an analogue voltag
e (maximum +5 volts) proportional to body movement.
Pr
ovide inputs to the adapti
ve damping control module.
The two vertical acce lerometers are mounted on the bulkhead and in the trunk.
The lateral accelerometer is mounted in the ECM housing.
Ada
ptive Damping Control Module (ADCM)

The ADCM
:
Is

mounted on the fascia support bracket.
Controls the four adaptiv

e dampers in re
sponse to analogue and digital inputs.

N: To preserve 'drive line' refine
ment, individual parts, other than fixings, MUST NOT be renewed. In the event
of any balance or driveshaft component related problem, the complete assembly must be renewed. Under no circumstances
may the flexible (Jurid) coupling be remo ved from the driveshaft (or its fixings be loosened). Do not drop or subject the
driveshaft to damage.
1. Disc
onnect the battery ground
lead and raise the vehicle for
access
2. Remove the front exha ust muffler, 30.10.18

3. Re
move the driveshaft from
the transmission flange.
If required, 'match mark'

the transmissi on flang and
coupling
Unscrew the fi xings (3)

4. Relea s
e the parking brake relay
lever mounting bracket fixings
(4) and allow the assembly to hang down

5. Disc onne

5. CAUTION: Under no circumstances must the
flexible coupling (or its fixings) be loosened or removed
from the drive shaft
1. 'Match mark' the FLEX IBLE COUPLING to the
differential DRIVE FLANGE
2. Remove the fixings (3)
6. Re
move the driveshaft
6. CAUTION: Ensure that the driveshaft front and
rear sections do not become disengaged. Secure the front
and rear sections to preven t sliding joint disengagement
during transport
