Accessory Relay: Description

WARNING: This page is about a different car, the 2004 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.

The accessory relay is an electromechanical device that switches fused battery current to the accessory powered vehicle circuits when the ignition switch is turned to the Accessory or On positions. The delay feature will maintain power to the accessories for 45 seconds after the ignition is shut off or until a door is opened. This allows sufficient time to close windows and park the windshield wipers. The accessory relay is located in the Integrated Power Module (IPM) in the engine compartment.

The accessory relay is a International Standards Organization (ISO) relay. Relays conforming to the ISO specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions.

The accessory relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced.
