Sharing, as it might just help someone now or later.

Since the last 3 months, had the dreaded CHECK REAR LIGHT warning coming up every now and then.
Always during operation of the brake pedal, and always disappearing on the next push.
Also had the ABS warning light sometimes, which always disappeared on the next start up.

Checked my bulbs and the connections several times (which I made clean and tight 2 years ago), but all was working and tight those times.

Then, 2 weeks ago, had the CHECK REAR LIGHT warning permanently, the right rear brake light not lighting up any more.
The ABS light came on shortly after that, and did not disappear, not with a re-start, nor with a hard reset.
Changed the bulb when home, and both messages disappeared, not coming back any more in an other 600 miles.

I checked the old bulb, and suspect the wires to be kind of crossing after one broke, hence the intermittent warnings, and lights still working most of the times.
I have no idea how, but it surely interfered with the ABS module.

So if you have intermittent ABS warnings only, you might check your rear bulbs before cutting into the module.

 

I've had an ABS/Trac message for weeks now & today I got a sporadic "check rear lights" that disappeared on the next crank, hmm.

 

I could not see anything wrong with the bulb until it finally gave the ghost. Replace them to be sure.

 

Yeah I'm in the process of knocking out my checklist on this on this gem. Today in audio shop, tomm it's in paint. I had the ABS codes pulled last week & it's surely in need of the solder fix. My question is can I have it removed & sent off to a rebuild service & still have the car operable.

 

MY abs light comes on when I put the car in reverse. Not necessary for the car to move. It will then reset when I turn the car off. As long as I go forward, the abs light stays off. As soon as I shift into reverse, it comes on. Any tips on what the problem could be/

 

The ABS light will not come on until it has failed 3 times and will not reset until you reach 12.5 MPH

so this dampening effect built in will throw off your observations and not be a direct correlation to a change like a component

 

98 Jag Xk8 ABS light
codes
C1233 Wheel speed front left - signal missing

C1155 Wheel speed front left - circuit failure

C 1145 Wheel speed front right - signal missing

I replaced the wheel sensors and harness and rebuilt the module. ABS light continues to come on.

 

You sure can. Don't need to detach brakelines either. Just bend brake pipes just enough. Lower bolts are slighltly more difficult to get to. Support the solenoids with something when packing unit up.
