Antilock Braking System / Traction Control / Coupled Braking System.

The ABS system is working perfectly.

I have recently (ie just) replaced the rear sensor with brand new, and replaced the inner casing of the final drive unit, with the bearings, seals etc.

The electronic control unit is in perfect working order, and performs a self diagnostic test - which I demonstrate in the video below. The unit will record faults with the wheel sensors, the modulator sensors and the electric pulse motors as well as with the power and the ECU itself. If there is anything wrong with the ABS system, the diagnostic test will store the last two faults.

In the video below, I have deliberately disconnected the new rear wheel sensor to show the ecu diagnostic test in operation. 6 flashes means there is a fault in the rear wheel sensor. (In this case, it's because it isn't connected).

The ABS system is what makes the ABS version of the Pan worth over £1000 more than the same age standard version. It is worth every penny. The brakes are sharper and the antilock/traction control really does work and inspire confidence. It is electronic and mechanical, and if it packs in, costs a fortune to put right. Sensors, and brake fluid modulators are very expensive, but dead easy to check for. The red ABS light in the centre of the dash should go out when the bike has been ridden for a few yards. Any faults are recorded in the systems computer, and can be recovered as shown in the video below.

The coupled braking system works well if the linkage at the front is properly maintained. This is hidden behind the shrouds on the left hand front mudguard. Some people don't like it, but it works well on the Pan. Look for rusted linkage behind the grey shroud.

Oh - and the new sensor bracket !
