ABS warning lamp

Correct operating sequence

Switch ignition ON. Warning lamp illuminates and then goes out after approximately 2 seconds.

Hydraulic system

Bleeding

System can be bled using normal method.
Bleed in sequence: RH rear, LH rear, RH front, LH front.
If using pressurised bleeding equipment, DO NOT allow pressure to exceed 1 bar.
DO NOT open bleed screws on hydraulic modulator.

NOTE: If air has entered the internal fluid circuits of the hydraulic modulator it may be necessary to use
special equipment that can activate the solenoid valves in order to successfully bleed the system.

Hydraulic modulator solenoid valves

NOTE: Solenoid valves are integral with the hydraulic modulator. They can only be checked using
diagnostic equipment.
