Rear Suspension-control Module - Operation Check










NOTE: The vehicle must be parked with its weight on its wheels

1 Check fluid level in reservoir, correct as indicated
2.1 Remove linkage rod or relay linkage (7) from suspension-control module lever (arrows)
2.2 Remove linkage rod for suspension-control module/torsion bar at ball joint

DANGER:
- Risk of accident from vehicle starting off by itself when engine running Risk of injury from contusions and burns if you insert your hands into the engine when it is started or when it is running Start engine and allow to idle
- Secure vehicle to prevent it from moving off by itself
- Wear closed and close-fitting work clothes

4 Press suspension-control module lever to position "fill" (F)

CAUTION: Because the pressures are considerable, keep test as brief as possible

NOTE: The rear of the vehicle should rise

- The suspension-control module's bypass valve limits the supply pressure of the hydraulic pump The bypass valve emits a whistling noise as it opens If the rear of the vehicle fails to rise within approximately 30 seconds

Model Series 140, 202, 203.2, 208
- Disconnect return line (T) from reservoir (2), if fluid emerges Replace rear axle level controller

Model 210
- Checking hydraulic pump If supply rate is within specification, but pressure is too low
- Replace rear axle level controller

Model Series 140, 202, 203.2, 208
- If no fluid emerges from the return line, Check hydraulic pump

5 Set level controller lever to" Empty" position (L)
6 Switch off engine
7.1 Connect linkage rod or relay linkage (7) to suspension-control module lever (arrows)
