Stop Lamp Inhibit Relay - Description
DESCRIPTION
A stop lamp inhibit relay (also known as the brake lamp activation relay or trailer tow damping relay) is part of the Electronic Stability Program
(ESP)/Traction Control System (TCS)/Brake Assist System (BAS)/Trailer Sway Control (TCS) package on this vehicle. The stop lamp inhibit relay is a
conventional International Standards Organization (ISO) relay. Relays conforming to the ISO specifications have common physical dimensions, current
capacities, terminal patterns (2), and terminal functions. The relay is contained within a small, square, molded plastic housing (1) and is connected to all
of the required inputs and outputs through five integral male spade-type terminals that extend from the relay base plate.
The stop lamp inhibit relay is located in a connector on the underside of the left front fender hydroform load beam in the engine compartment.
The stop lamp inhibit relay cannot be adjusted or repaired and, if ineffective or damaged, the unit must be replaced.
