The methods described here are mostly explained in the workshop manual

MKI (SC58) Section 17 pages 8 to 10 and the ABS problem code index is on page 11.
MKII (SC64) Section 15 pages 13 to 15 and the ABS problem code index is on page 15

Remove the seats. Locate the ABS Service Check Connector, an oval 3P natural colour socket that can be found below the riders seat in a clear plastic sheath between the main fuse box and the ABS modulator. It is closed off by a dummy connector, depress the tab to remove it and you’ll see three female terminals, the wires are coloured

•   Orange/blue (Diagnostic)
•   Brown/white (Service Check Short)
•   Green/orange (Chassis ground)

With the ignition switched off short the Brown/white and Green/orange wire terminals with a jumper wire or paper clip.
Turn the ignition switch on and watch the ABS indicator lamp it should come on for 2 seconds, off for 4 seconds. Then if there are no stored fault codes the ABS indicator lamp comes on and stays on. If there are any stored fault codes the ABS indicator lamp will flash them.

The ABS indicator lamp has two types of flash, a long 1.3 second flash and short half second flash. One long flash equals ten short flashes. For example, when two long flashes are followed by three short flashes, the problem code is 23 (two long flashes equals 20 plus three short flashes equals 23). When the Engine Control Module (ECM) stores more than one problem code, the ABS indicator lamp will flash them out in the order of the lowest code first, the lamp will keep flashing the codes so let it do two cycles to be sure. When finished turn the ignition switch off and remove the jumper wire.

Clearing stored ABS fault codes

With the ignition switched off short the Brown/white and Green/orange wire terminals of the ABS Service Check Connector with a jumper wire or paperclip.

Turn the ignition switch on while pulling on the front brake lever. the ABS indicator lamp should come on for 2 seconds and then go off. Release the brake lever immediately the ABS indicator lamp goes off.

The ABS indicator should then come on, pull on the brake lever immediately the ABS indicator lamp comes on and the ABS indicator should go off, release the brake lever immediately the ABS indicator lamp is off.
When code erasure is complete, the ABS indicator lamp flashes twice and stays on.

The sequence is

•   ignition + brake on, lamp on, lamp off, release brake
•   lamp on, brake on, lamp off, brake off, lamp x2 flash, lamp on

Job done, turn the ignition switch off, remove the jumper wire and re-fit the dummy connector.

A note on stored ABS fault codes.

TC12 'front wheel speed sensor circuit malfunction' can be caused if you run the engine in gear on the centre stand, for example to oil the drive chain, what happens is the ABS module receives a signal from the rear wheel but not the front wheel.

TC61 'power supply low voltage' is just that and most likely caused by a previous low battery voltage condition.

Just to be perfectly clear the explanations above apply to stored fault codes, if the codes are current codes with the ABS light on then they need to be investigated further.

I remember to have done it once, after a front tire change I got a fault, the ABS ring was slightly bend due the transport (I had the wheel out and take it to the tire fitter). Because the ring was bend the abs-sensor did not read pulses during a section of a wheel revolution. I gave an error.
The ring was easily bend back into shape, problem solved. There's some intellect in the bike  :015:
Thanks for making a dedicated thread  :028: :028: :028:
