Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
How is the brake fluid level? Does the ABS light only come on when braking? Or does it only come on after you start to drive over 20 mph?
Let me know.
If the light is off until you start to drive that is a indication of a ABS sensor. It will require a scanner to monitor sensors since you have one on each wheel to determine which sensor is turning the light on.
If you have a Engine Speed Signal code in the ABS system, that is a sign of a bad Cam sensor developing. When it comes to electrical parts and sensors, I always recommend you use parts from the dealer. After market electrical parts never work right.
If you have any more questions on this, please feel free to ask.

When it comes to the ABS system, if you had a code for the left front sensor, I would start with replacing that sensor.
There is really no tricks to the ABS system. It requires a scanner to isolate issues so they can be resolved.
You can't always go by the resistance. It could be a toner ring, but not likely. I would recommend you start with a sensor first.
Oh.. well that could indicate it could be a issue with the abs actuator internally. The Actuator is also the ABS control unit. So that could explain some abnormal ABS lights and operation.
the actuator is normally down on the left front of the truck under the hood. Tire sizes if changed to much could cause premature abs issues or false readings.
