I recently had my service ASR / ASR off lights come on simultaneously. I have checked the brake fluid which is OK. I have noticed a clicking noise in the left rear when the brakes are applied. Could this be a bad caliper? and could it trip these 2 codes? I checked the speed sensor on the hub and cleaned off the dirt but still have the lights on. I have not gone deeper to check the hub. Anyone have any hints or insight into this?
