Is there a relay for DRL and head lights 2002 toyoto corolla?

The 2002 Toyota Corolla does not have a specific relay for daytime running lights (DRL) and headlights. Instead, the DRLs and headlights are controlled by the body control module (BCM) and various sensors. Here's how they work:

DRL Module:

There's a DRL module located in the fuse box under the hood. This module receives signals from the ignition switch, parking brake switch, and headlight switch. Based on these signals, it controls the operation of the daytime running lights.

DRL Circuit:

The DRL circuit includes the DRL module, DRL bulbs, and the necessary wiring. When the parking brake is disengaged and the ignition is turned on, the DRL module powers the DRL bulbs, causing them to illuminate.

Headlight Circuit:

The headlight circuit consists of the headlight switch, headlight relay, headlights, and associated wiring. When the headlight switch is turned on, it sends a signal to the headlight relay. The relay then supplies power to the headlights, allowing them to light up.

In summary, the 2002 Toyota Corolla relies on the BCM, DRL module, headlight relay, and various switches and sensors to control the operation of the DRLs and headlights. There is no separate relay specifically for DRLs and headlights in this model.
