Normal Operation
The DSM communicates with the scan tool through the medium speed controller area network (MS-CAN). Circuits 2180 (WH/BK) (MS-CAN +) and 2181 (BK/YE) (MS-CAN -) provide the network connection to the DSM. The DSM shares the MS-CAN network with the smart junction box (SJB), the audio unit, the electronic automatic temperature control (EATC) module, the digital versatile disc (DVD) player, the satellite radio receiver, and the instrument cluster. Voltage and ground for the DSM module is provided by circuits 566 (DG) and 956 (OG/LG). Circuits 1203 (BK/LB) and 1205 (BK) provide ground.
Possible Causes
- Fuse
- Circuit 566 (DG) open
- Circuit 956 (OG/LG) open
- Circuit 1203 (BK/LB) open
- Circuit 1205 (BK) open
- Circuit 2180 (WH/BK) open (MS-CAN +)
- Circuit 2181 (BK/YE) open (MS-CAN -)

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.
