Warning: Before starting work, ensure the motorcycle is stabilised and adequately supported. This will help prevent it from falling and causing injury to. the operator or damage to the motorcycle.
1. Complete the brake bleed procedure as for models without ABS brakes (see page 14-23).
2. Connect the Triumph diagnostic tool (See page 14-48).
3. Follow the on screen menu to ABS Diagnostics. From the menu, select BLEED SYSTEM (see the Triumph Diagnostic Tool User Guide).
Note:
- On pressing the Start button, the diagnostic software will send a command to the ABS ECM to open the 2nd circuit solenoid.
- The rear brake pedal travel will increase as ABS modulator solenoids are opened and will then decrease as the solenoids are automatically closed.
- Pressure must be applied to the rear brake pedal before operating the bleed sequence on the diagnostic tool. An assistant will be required to open the bleed nipple while pressure is applied to the brake pedal.
4. Apply pressure to the rear brake pedal, press the Start button to activate the bleed sequence on the diagnostic tool, and with assistance, release the bleed nipple.
5. Slowly depress the brake pedal and, holding the pedal fully down, close the bleed nipple. Repeat until no more air appears in the bleed tube, maintaining the brake fluid level between the upper and lower reservoir levels whilst bleeding is being carried out.
6. The bleed sequence will run for a maximum of 90 seconds. Press the Stop button to end the bleed sequence at any time. Once the bleed sequence has completed the diagnostic tool will display a message 'ABS system bleed complete'.
Caution: The ABS modulator must be allowed to cool between bleeding operations. Always allow the ABS modulator to cool for 5 minutes before starting the bleed procedure again. Failure to follow this instruction may result in damage to the ABS modulator.
7. Repeat the above procedure as necessary until all air is expelled from the system.
8. When all air has been expelled from the system, hold down the brake pedal and close the bleed nipple. Tighten the nipple to 6 Nm.
9. Repeat the brake bleed procedure as for models without ABS brakes (see page 14-23).
