The Bosch Solenoid Pack is part of the Bosch 5.3 ESP (Electronic Stability Program) System. It is bolted directly to the hydraulic control unit, and because it contains only solenoids, seldom ever fails. The solenoid pack is hardwired to the hydraulic pump motor and has a 15-pin connector.
The source of most failures is the control module located behind the glove box or under the rear seat. This is the module you’ll need to replace. Unfortunately, we cannot repair it either.Button Text
