The Security Gateway Module (SGW) is in the audio and telematics Controller Area Network (CAN) systems to provide security against certain types of attacks and threats from the scan tool, telematics and entertainment buses, which can put the rest of the vehicle's buses at risk of intrusion. The SGW lies electrically between the vehicle on one side, and the Data Link Connector (DLC), telematics and entertainment systems on the other side. The main function is to gate messages from one bus to another. The SGW monitors the B+ Feed, switched ignition feed, CAN circuits, software and hardware for any concerns.
On vehicles equipped with an amplifier, the radios use a different strategy for the four channel output. The left front channel is used for Voice Recognition (VR) and navigation turn-by-turn direction audio, the right front channel is used for cell phone audio. The rear channels are used for stereo, right and left channel, output to the amplifier. The signal data from the antenna, USB or AUX inputs on the rear channels is split logically so that it appears to the occupant to be surround sound. With this channel strategy, there is the possibility of additional symptoms of "no audio" from either the navigation system or the cell phone that will not set a Diagnostic Trouble Code (DTC).
The radio is responsible for sending video streams to the Instrument Panel Cluster (IPC) for music album art, phone contacts, and navigation map if equipped over the Automotive Ethernet network.
Hardwired circuitry connects the radio to the electrical system of the vehicle. These hardwired circuits are integral to several wire harnesses, which routes throughout the vehicle and retained by many different methods. These circuits may be connected to each other and to the vehicle electrical system through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds. For proper wire repair, and connector repair procedures. Refer to WIRE SPLICING , CONNECTOR TERMINAL REMOVAL and CONNECTOR TERMINAL INSTALLATION .
The radio cannot be adjusted or repaired. If the radio is damaged or ineffective, it must be replaced.
OPERATION
The SGW is the CAN gateway between the radio, telematics modules, DLC and the other vehicle CAN modules. An SGW failure could prevent the radio from powering up, telematics module from communicating or a scan tool from communicating with the vehicle. For additional information on the SGW, Refer to MODULE, SECURITY GATEWAY (SGW), DESCRIPTION AND OPERATION .

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
