ABS circuit issues.
 

I have an intermittent problem – my favorite type.

Often within a couple of minutes when cold and randomly otherwise I get the brake and interlock lights on with the buzzer and master alarm. After canceling the buzzer the two warning lights stay on until the car is stopped. They do not then immediately reappear at startup….. I understand this combination of lights indicates an ABS issue. A quick Hammer shows a code associated with the right left ABS sensor. The relay has recently been replaced and the sensor contacts appear clean.

Does anyone know of a weak spot, either the sensor itself, some point in the wiring loom or elsewhere???

Thanks

From other posts, IIRC, if it is not the sensor, it might the the ABS control unit. You really need to get it on a Bosch Hammer to know for sure.
