RepairPal Expert Overview:
The Hydraulic Electronic Control Unit (HECU) is part of the Anti-Lock braking system. The vehicles being recalled may have been assembled with brake fluid that does not protect the HECU from corrosion. If the module were to corrode, braking effectiveness could be reduced, increasing the risk of a crash. For vehicles manufactured prior to June 01, 2010, dealers will change the brake fluid and inspect the HECU, repairing it as necessary. For vehicles manufactured after June 01, 2010 dealers will flush the HECU assembly and brake system and change the brake fluid.
