I've got a 97 JGC and the ABS light is always on. I have sufficient fluid levels and life on the pads. Any advice?

Could be a bad sensor. Any codes?
1st I would take the tires off. Unbolt the sensors. Clean them (wipe them off) and see if that helps. It's only one bolt per sensor and shouldn't take too long.

Follow your wires from the sensors at each wheel and make sure the connections are good. If they have been cut and spliced back together anywhere, that's not good. There is also an ABS relay you could try to replace.

Is it still safe driving JGC(1996) even the abs light is on? It turns on intermittently.

I have a Jeep Cherokee KJ (Liberty in the States) and had an ABS warning light come on. Had changed the discs and pads recently so knew it couldn't be them. Checked the fuse etc, all good. It wasn't until I checked for continuity on the ABS wiring connector on the rear axle (leads to the rear wheels sensor) that I found that the connectors were just a bit dirty. Gave them a good prod with my multimeter and found that the light went out. Took a while for the light to go out though. I think the ABS brain has to receive positive readings from the wheel sensor whilst in working action before cancelling out the fault light for good. It went out after depressing the brake repeatedly and driving for about 3 or 4 minutes.

I'm certainly no mechanic and did this with limited knowledge so I urge people to have a go before letting the dealerships take your money. Hope this helps.

I would say that it definitely isn't safe to drive without ABS in the wet. I had the rear wheels locking up even when I was braking gently. Have a go and you'll find it's easier to fix than you think.

ABS Cable:
I own a '95 KJ Renegade fitted with factory alloy rims. Recently the ABS warning light stayed on and at about the same time the radio picked up static noise when the vehicle was moving. the static increased in frequency when the speed increased. I also had a situation in a carpark when on full lock the vehicle brakes appeared to engage until I turned the wheels straigt ahead. This was all very baffling until I checked the braking system to find that the ABS sensor cable and the two sensor wires in the cable had worn through on the front left hand wheel rim. this accounted for the warning light and the radio static(bare sensor wires rubbing on the metal rim)I soldered the wires together and double insulated them with heatshrink. I also tied the cables back and away from the rims on both front wheels with cable ties. The right hand cable also showed signs of rubbing. I consider this to be a potentally dangerous design fault. It rendered the ABS ineffective and also applied the brakes at times when not required when the bare wire ends shorted on the wheel rim.
Is this a common problem? Have sensors been replaced wrongly when it was the cable at fault.
I would be interested to hear of any other person who has had the same problem.

ive been a mechanic for over 12 yrs now and first thing i check when an ABS light is on is the wheel speed sensors and connectors...most people think since it has brake in the name that there fluid is low or there brakes need replaced this is not true and in no way is gonna set an ABS light...check the speed sensors, connectors and wiring, and finally the module-or go to advance auto and the can scan the vehicle and tell you if a sensor is bad and what one...for free

Sounded and felt like something fell off of my car but I thought it might have been a chunk of ice but it was dark and I couldn't see. When I took a few left turns it felt strange. Next morning these lights were on. The snow plows came over night and I don't know if I can see what I ran over. Any suggestions?

No you dont have to have it reset, when you do hubs, the abs module "depending on if ur abs module is working" will collect information from the teeth on the axel or the wheele bearing. nothing you need to do after you install them.....would be a good idea to dissconnect the battery before you replace them to reset the computer in the car while your working on the sensors.......when the battery is reconnected and the new parts are installed....the computer wont even know they are replacement parts or that there was ever a bad sensor
