My ABS light has been a problem ever since my dealer changed the air compressor. Ay first both the ABS and Traction Control Lights were lit. The dealer replaced the control unit and both lights went off. Soon, both lights would go on and off intermittently. For the past three weeks, only the ABS warning light is on. My dealer wants me to pay for another control unit. Are there any sensors, etc. that would throw a PC1602 code, or affect the funtioning of the ABS. Another computer is an expensive proposition.

Thanks,
