What a time I had with mine ( 2007 VVT)
Clearly you have to ensure the rings are intact and not damaged as noted above
ALSO the magnetic tips are not covered in crap ( light wire brush)
wheel bearings can through the sensors out too.
# eventually took the calipers off and cleaned the ring, very rusty and muddy
I used a little dremel and file but only lightly to show a bit of shinny metal peak and trough of the teeth.
I also worried about air gap but never got a definitive on that one, I have a gap of about 1-1.5 mm on one side and 1mm on the other, I did put an any corrosion spray on the ring which actually washed off after about 6 months in off road/road use but all worked again
If the ECU is carrying old bad codes, tack the negative battery terminal off the battery for 10 mins and reconnect, seams to get rid of old codes ( i think)
Was worried about the plastic sleeves which isolate the sensors from the carrier
( always break but squeezed them in on two half's per side).
Anyway, that worked for about a year and recently same flashing ABS so
repeated the above process but to no avail.
I pulled them right off the car and found a crush to one cable
they are a bit sensitive and can be troublesome after a while
The sensors are a two sided loom and £200 from Sims on Ebay
HOWEVER I purchased an after market set from stock here in the UK for +/-£20 2-3 weeks ago
They are perfect, ready to clip in ( SKV a reputable aftermarket manufacture from Poland)
as follows:-
ABS sensor front left or right; SUZUKI Jimny 1998 - 2000 ; 5620081A40

[they are exactly the same as the ones I took off on my 2007] and come with the little plastic sleeve insulator already on the sensors.

The above work is not too taxing for entry DIY, getting the 6mm bolt that holds the sensor in the carrier is the worst bit , so take your time with them !

Hi
I’ve removed both front wheels and discs to find both reluctor rings in good order, no missing teeth or cracks just slight surface rust which I removed with an old toothbrush. The ends of the sensors had a few rusty crumbs which again i brushed off thinking this would solve the problem however now the light is on from start up and I never touched any of the abs wiring! Will try the flash test as suggested tomorrow.

Did you clear the codes from when you 1st unplugged the sensors to check for voltage?
Might be worth clearing the code in the way larnach suggests, then trying again.
If you unplugged each sensor to check the voltage with the ignition on, you potentially have 4 fault codes!

Hi
I’ve read the code this morning which is 61, abs pump motor circuit (going to recheck tonight in case it’s 16, but 99% sure it’s 61).

I didn’t have the ignition on when the abs plugs were disconnected.
The code wouldn’t clear this morning, presuming that’s because it’s a permanent fault?

Is the motor replaceable separate to the pump ?
Thanks everyone

If the fault wont clear it means it exists when you are checking it. Which would suggest the fault is more to do with something electrical than mechanical.

I know loads of people are going to tell tales of faulty ABS pumps etc. but before you do anything check the fuses, all the fuses and (with the ign off) unplug the ABS control unit and have a close look at the terminals in the unit and the plug.

I dont have access to the correct manual at the moment but from memory Suzuki manuals are good at telling people to swap or replace control units. Users of the manual always seem to skim past the start of the manual that states it is for guidance only.

I know the pump and control unit are available seperately for some cars but if I were you and I was 100% the pump or motor was dead I'd probably stick a 2nd hand complete unit on rather than source one or the other.
