DESCRIPTION
Vehicles equipped with the optional Hybrid Electric Vehicle (HEV) system have a Hybrid Gateway Module (HGM) (1) that is secured with three screws to the stamped steel Transmission Auxiliary Oil Pump (TAOP) control module mounting bracket located on the left hydro form (frame rail) near the back of the left front wheel housing within the engine compartment of the vehicle. Concealed within a hollow in the center of the die cast aluminum HGM housing is the electronic circuitry of the HGM, which includes a microprocessor and an electronic printed circuit board. A stamped metal cover plate (2) is sealed and secured to the HGM housing with four screws to enclose and protect the internal electronic circuitry and components.
Two molded plastic electrical connectors (3), one containing 24 terminal pins and the other containing 12 terminal pins, exit the forward facing side of the HGM cover plate and are pointed downward. These terminal pins connect the HGM to the vehicle electrical system through two dedicated take outs and connectors of the headlamp and dash wire harness. The HGM housing has integral mounting flanges on two sides with three mounting holes in each flange. The mounting flange to the left of the connector receptacles is secured to the TAOP control module mounting bracket with two screws, while the flange on the right side is secured to the bracket with only one screw.
The HGM cannot be repaired or adjusted and, if damaged or ineffective, it must be replaced.
