Brake Lamp Relay: Description and Operation
Description
DESCRIPTION
Vehicles equipped with an optional Electronic Stability Program (ESP)/Traction Control System (TCS) package have a stop lamp inhibit relay. The stop
lamp inhibit relay is a conventional International Standards Organization (ISO) micro relay. Relays conforming to the ISO specifications have common
physical dimensions, current capacities, terminal patterns, and terminal functions. The relay is contained within a small, rectangular, molded plastic
housing 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 the Junction Block (JB) in the passenger compartment under the driver side end of the instrument panel.
The stop lamp inhibit relay cannot be adjusted or repaired and, if ineffective or damaged, the unit must be replaced.
