does anyone know what that means when both are on???

*stab in the dark*

ETCBM.. (Electronic Traction Control Brake Module) essentially the ABS brains. .go get a mortgage they wanted $1100 CDN for that part on my car :?

On my 94 SE when that happened it turned out to be my wheel bearing. It ended up costing me about 500.00 when done with a lifetime warrenty on the bearing

EBCM or EBCTM is a remote possibility at best. I've yet to see one fail. Most likely culprit is one or more wheel speed sensors or associated wiring (not the bearing as stated, either, but the sensor is an integral part of the hub assembly), or the PMV (another very expensive part).

Diagnosis is Dealer-only (special serial reader) and usually costs a minimum of 80 bucks. I suggest you inspect the wiring to all 4 wheel speed sensors first.

OOPS! Sorry forgot to also include that when my ABS and Traction Control Lights came on the ABS kept coming on. Id be driving about 10 kph all of a sudden the ABS would come on.

I think the ABS just comes on initially when in motion for self diagnostic purposes.. definitely check the wiring and speed sensor hub/bearings.. I have the exact same issue.. just broken wire going to rear passenger side wheel bearings that'* broken.. and too lazy to fix.

I also have a 97 Transport. The ABS/Traction Control light comes on in rain only. Could that be a loose wire or sensor that gets wet?

since i work at napa the diasnostics is free and i was told front left speed sensor will b fixed with timin chain this weekend

Sure sounds like an open wire and or loose connector. ( That would be my first guess ) since when it rains.. if you're wire is open.. it'* shorting itself somewhere. The other thing I can think is the speed sensor has a leak somewhere allowing water in. Check wires/ connectors first.. they're the easiest and cheapest.

I have the same issue. ABS would engage at any time.. and would eventually disable itself and set the ABT and TC lights to come on. My cousin and I (actually it was all my cousin.. I just watched) diagnosed it to be a sensor.. and just happens to be the same one that the wheel bearings are making noise. Maybe the wheel bearing failure caused the sensor to malfunction as well. Anyway, my question is, what size is the main hub bolt?? We've had reports or 33mm or 36mm.. does anyone know? Thanks
