C1144

Under normal driving conditions, i began to notice my abs light would intermittently illuminate. I took my vehicle to my local authorized Ford dealership and i was told my abs module was faulty along with the left front wheel speed sensor. I was given the following results, C1155 - lf speed input fail C1185 - power relay circuit fail other codes below are caused by C1185 and C1155 C1144 - wheel speed sensor rr tone ring tooth missing fault C1198 - abs inlet valve coil lf circuit failure C1210 - abs outlet valve coil rf circuit failure C1214 - abs inlet valve coil rf circuit failure C1233 - speed wheel lf input signal missing C1242 - abs outlet valve coil lr circuit failure C1250 - abs inlet valve coil lr circuit failure recommend replacing abs ecu module and l/f speed sensor. The failure was intermittent over the past year but over the past month the abs indicator lamp is always on. The issue has not yet been corrected as i wanted to look into the issue more. Some quick searching on google quickly brought up that i am not an isolated incident but one of many. I had found on many websites that C1185 is related to the expanding and contracting of the heatsink on which the abs ecu is mounted. The result is the abs ecu fails to power on correctly due to the stress placed on the sensitive electronic board. I am assuming that the l/f wheel sensor is a separate issue but with a bad abs ecu, it could possibly be related.
