Peugeot Satelis - Service manual > Reminder

The ABS/MBS features 3 distinctive functions:

1. Combined front and rear braking system controlled by the LH brake lever.

2. Braking assistance system provided on the front wheel.

3. Anti-locking system provided on the front wheel.

Before servicing the system, carry out a diagnosis using the diagnostic tool and print out a parameter report.

If fault codes appear, repair as required.

The diagnostic light of the system only goes off when the machine reaches 5 km/h.

The rider brakes with the left lever (integral braking), and the right lever (braking on the front wheel only) becomes an emergency brake.

For diagnosing the ABS/MBS system, see document: ABS/MBS braking system functioning principle. Reference: 759568.
