Circuit Description

WARNING: This page is about a different car, the 2006 Toyota Tundra and 2005 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

The motor relay (semiconductor relay) is built in the master cylinder solenoid and drives the pump motor based on a signal from the skid control ECU.
