2000 ML430 BAS ESP ABS light comes on when turn wheel to the right
Hello all! i am new and have enjoyed the all info i have read. here is my issue: 2000 ML430 BAS ESP ABS light comes on when turn wheel to the right. I believe there were actually 2 issues but i have managed to repair all but this last one. Initially, i could also feel the ABS activating interrmittently when pressing the brake. below is THE list:
Step 1 - replace brake switch - no change
2. - check tire pressure and size - good
3. - test battery with it started or not with a voltmeter - 12.4v & 13.8v-good
4. - remove battery cable for 3 minutes to reset then recalibrate - no help
5. - check transmission connector & found fluid! Cleaned it. ABS issue fixed!
Some maintenance history: all brakes were replaced about a year ago, tires new about 2 years ago, 210,000km, truck drives only about 12,000km/year.
Test drove & lights went out after cleaning the tranny connector. Turned wheel all the way to the left & no problem. Turned wheel all the way to the right and the lights came on again. If I drive for a bit & shut off vehicle the lights will go out until the infamous sharp right turn. The moment the 3 lights come on the ABS will go off(when press brake).
I suspect wheel sensor or wiring?
