Lexus Troubleshooting Questions? Ask a Lexus Expert
Hi! Welcome to JustAnswer. I'm Ron Z and I'll be helping you with your question today. Unfortunately, there is no easy, 1-answer, "it's this..." type of answer here. When the ABS and VSC lights are lit, there is a problem with one of the sensors that these systems share. Unfortunately, there are dozens of sensors that are used for both systems. A very common fail item here is a Wheel Speed Sensor. There is one of these for each wheel. The outputs from these sensors are used in both ABS and Vehicle Stability. So, this would be the best place to start. Inspect the electrical connector and wire harness to each sensor for any loose, broken or damaged wires. Inspect the tone-ring that the sensors read and make sure there are no missing teeth or debris that may be blocking the signal to the sensor. If there is nothing visual that stands out, then at this point we'll need the Diagnostic Trouble codes. These codes will more accurately and efficiently point us in the direction of the part or sensor that has the fault and from there the correct repair can be made. SOME local parts stores, like AutoZone, will have the correct scan-tool to read these codes. If you can find one that does, they will do so for Free (except in California). If you cannot find a parts store to read the codes, then unfortunately, a shop will be needed. Again, sorry I could not be more specific, but like I say, too many parts and sensors shared to take a guess and be correct.
