The headlamp high beam relay is a conventional International Standards Organization (ISO) micro relay. See Fig 1. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. This 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 headlamp high beam relay is located in the Junction Block (JB). This relay is omitted from vehicles manufactured for sale in Canada, which have a Daytime Running Lamp (DRL) solid state relay installed in the JB that also performs the high beam relay function.

The headlamp high beam relay cannot be adjusted or repaired and, if faulty or damaged, it must be replaced with a new unit.
