The problem
The anti lock brake system (abs) pressure/warning switch may exhibit brake fluid seepage which eventually can lead to loss of the brake system hydraulic pump motor. Additionally, the hydraulic pump motor and abs electrical relays may have been exposed to water contamination during vehicle assembly. This condition can cause loss of the hydraulic pump motor and/or loss of the abs function.
The risk
Loss of the hydraulic pump motor would result in a totalloss of rear brakes as well as power assist to the front brakes. The red brakewarning light would illuminate and stay on. If this warning is not heeded, aloss of rear brakes at a time when minimum stopping distance is required couldresult in a vehicle crash. An inoperative abs electrical relay could causeloss of the abs function, but normal power assisted braking would be retained.The amber anti lock warning light would illuminate and stay on.
The fix
The abs and hydraulic pump motor electrical relays and 30 amp fuses will be replaced. In addition, the hydraulic pump motor assembly and pressure/warning switch will be inspected and, if required, replaced.
