06 Malibu Maxx ABS/ Traction / Brake Light is still on after replacing wheel bearings. I replaced both Rear wheel bearings, and the code states erratic wheel speed sensor left Rear
Company won't replace wheel bearing because they said wheel speed sensor
is not built into the wheel bearing? I cannot find anything that states this, and
this seems very innaccurate. Would there be any other reason why the light
would be on?
Sometimes when Fixing the Problem is fixed the light will stay on. That means you gotta reset the computer! Some vehicles you can take the Terminals off the battery for about a minute and that will fix your problem by resetting it itself. Good luck!
Wrong the sensor is part of the hub assembly. See pic. There have been some problems with the harness to the sensor so that should be checked also. more techincial would be: The LR wheel speed sensor circuit is as follows: Terminal A, TAN wire, supply voltage from EBCM terminal A5 Terminal B, ORG wire, sensor signal to EBCM terminal A6 1. Take the electrical connector off the left rear wheel bearing/hub assembly and then inspect to make sure there's no problem with the connectors mating (bent pins, pushed in sockets, etc.). 2. The resistance across the wheel speed sensor itself should be virtually nil. 3. Verify a minimum of 8V on the TAN wire from the EBCM with key on. 4. With key off, take the electrical connector off the EBCM (that's the box with two brake lines going in and four out, below the brake master cylinder) and then verify each of the two wires that go to LR for continuity and short to ground, to voltage, or to each other. Hope this gives you some information you need.
